APPLICATION
The blotter spot test dates back to the early 1950s. It is one of the oldest techniques used to identify
excessive engine soot, evaluate a lubricant’s dispersancy and detect the presence of glycol, fuel and other
contaminants in engine crankcase lubricants.
For large fleet operators, oil conditioning monitoring laboratories, this simple, yet powerful technique can
provide valuable information when used as a screening tool.
Though this method has proven effective, individual subjectivity in readings oil spots affects the reliability
of results.
To help oil analysts taking most advantage of this valuable traditional technique the company AD systems
in cooperation with a lab dedicated in Oil Conditioning Monitoring (OCM) has developed a modern
automatic instrument offering significant increase in accuracy and repeatability of measurements.
The DT100 is the only instrument that automatically and simultaneously measures the dispersancy and
the soot contamination of the lubricating oil.
This new technique removes all the arbitrary aspect of the manual method.
The oil spot is illuminated with a stable and consistent light source. A CCD camera takes a picture of the
oil spot in monochrome mode and with backlighting. In couple of seconds the sophisticated software
scans and analyses all the different areas of the oil spot calculating valuable in-use oil quality parameters.
- The dispersancy (MD) is key indication about the detergent capacity of the oil to disperse and melt
particles. MD is expressed by an index from 100 (ideal) to 0 (no dispersancy)
- The contamination index (IC) representing the percentage of insoluble matters in the oil (measurement
limits: 0.1 to 4.8%).
- The Weighted Demerit (DP) which is a mathematical combination of the two above mentioned
parameters DP = (100 –MD) * IC. The DP is essential parameter for trend monitoring.
Optional version of DT100
The DT100 DL (Dual Light) version of the instrument is equipped with color camera and additional direct
light source. Then calculations are done, the DT100 DL switchs the camera in color mode, turn off the
backlight illumination and flash the spot with front light in order to record color image of the spot in
direct lighting as it is seen by human eyes.
Both spot images : monochrome picture and with backlighting and color picture in direct lighting are
stored on USB device or sent to local network.
In addition, the DT100DL offers sample ID “tagging” by stamping the sample ID into the spot bitmap
image.
The DT100DL offers full test traceability. The spot image is easily identified along with reported results
making it ideal for quality process documentation, reporting and electronic archiving.

HOW TO PREPARE THE OIL SPOT
The spot method (or blotter test) is a simple but valuable test that provides unique information on oil
dispersancy for laboratory oil conditioning analysis program.
A drop of oil is poured on a filter paper
The drop spreads on the paper
The oil with contained particles penetrates into the filter paper. Due to the lamination phenomenon of
the oil film, the particles of same size depose on the paper on the same concentric zone. The distribution
of the different zones will reflect the status of the used oil.
Caution!
Quality of the oil spot and, as consequence, the quality of measurement depends on the filter paper
grade.
When the instrument is used in Oil Conditioning Monitoring program, the proper oil trend monitoring is
of importance. To obtain repeatable and reproducible oil dispersancy results, it is essential to use high
quality filter paper of the same grade.
We strictly recommend using the filter paper Durieux type 122 (Ordering Part Number: AC110-001).
Please contact AD systems for information.
Important!
Besides the proper grade of the filter paper, other factors can influence the oil spot.
In order to obtain precise and reproducible test results, the following requirements need to be carefully
respected:
- Use the recommended filter paper grade (as mentioned above)
- Drop the oil sample in the centre of the hole in the holder (use Drop Guide for micropipette available
from AD Systems – refer to the section “Spare Parts” of this manual)
- Respect the oil volume of 20 L. Use the dosing pipette. Higher or lower sample volume will result in
different size of the oil spot after drying. This will affect the measurement of MD and DP parameters.
- Always use the paper holder during drying to prevent the filter paper of creasing or warping
- During drying phase, keep the paper holder in horizontal position. Inclination of the holder during
drying can result in developing non-circular shape of the oil spot. This can affect the precision of the
measurement.
- The filter paper with oil drop should be free from touching any surface or object during spot
development.
- Before the measurement remove the paper sheet out of its holder.
9 Doc : AM110-001E Release: 1.2.4.4 updated : Aug2010
Procedure of oil spot preparation:
1. Take a filter paper sheet and position it in the filter paper holder
2. Shake the container with the oil sample to be analyzed.
3. With a micro pipette able to precisely dose 20 l of oil, take 20l sample of oil.
4. Wipe the outer surface of the pipette tip from the excess of the oil and pour the sample in the center
of the hole provided in the holder. We recommend to use the Drop Guide for micropipette available
from AD Systems (refer to the section “Spare Parts” of this manual)
The guide (P/N AK110-004) is placed on the hole in the filter holder and assures vertical position of the
micro-pipette tip in the center of the hole and always on the same distance to the filter paper. The
technician needs just to push the piston to get perfect drop.
AK110-004 AK110-005 / AK110-006
For labs running many tests a day, can use a guide assembly of 4 places (P/N AK110-005 and AK110-006)
which helps to improve test precision and save time on spot preparation.
The AK110-005 is designed for a row of 4 holes of 50mm with step of 52mm.
The AK110-006 is designed for a row of 4 holes of 50mm with step of 65mm.
Note: 16 oil spots can be prepared on one single sheet of 260x260mm. However, in general, only 15 oil
spots are prepared and the sample batch number is written on the upper corner of the paper sheet.
If you follow this notice, please write the batch number first, before sampling; in order to not disturb oil
spots development afterwards.
5. The paper holder with the paper sheet is then placed in horizontal position for 60 minutes in
laboratory drying oven adjusted at 80°C.
6. After 60 minutes, remove the paper holder from the oven.
10 Doc : AM110-001E Release: 1.2.4.4 updated : Aug2010Caution!
The holder metal surface will at 80°C, use protecting gloves to take out the holder from the oven
7. The paper filter is extracted from the holder and oil spots can be analyzed with the DT 100.
Important!
After the 60 minutes drying phase @80°C, the oil spot may continue
its expansion.
In order to obtain precise results, the oil spot must
be analyzed within 15 minutes after the extraction of
the filter paper from the oven.

After calibration the DT 100 is ready for oil spot measurement.
To perform a measurement, test sequence identification has to be entered first. Under the term “test
sequence” we understand a sheet of filter paper with number of spots to be tested.
SET Sequence menu – is to define mode of testing, the sample ID, number of spots and the correlation
type to be used for series of spots.
Press “SET sequence” button. The following menu will appear:
In the SET Sequence menu there are a few options allowing flexibility in programming.
Spot Name mode
Sequence ID is mandatory for start testing.
The name of the test sequence will be used as a filename to store result data on USB
On your choice, three modes for spot identification are available:
Incremental Sequence ID. If this box is checked, the Sequence ID should be a number.
Touch the red area to enter the value. The maximum number of characters for sequence ID is 6 numbers.
Each next spot will have automatically incremental number starting from to the number of first spot.
For example, you have to test 20 spots on the filter sheet :
Sequence ID: 48501
Spot Qty: 15
The first spot will get the ID: “48501”, the next – “48502”, “48503”, 48504”… till “48515”
Sequence ID extension. If this box is checked, it is possible to give a sequence name with alpha-numerical
characters. Touch the red area to enter the value. The maximum number of characters for sequence ID is
6 alpha-numerical characters.
19 Doc : AM110-001E Release: 1.2.4.4 updated : Aug2010Each spot will keep the sequence ID and add an order number for every spot separated with a dash.
For example (as shown on the picture below), you have to test 20 spots on the filter sheet :
Sequence ID: SPOT
Spot Qty: 20
First spot will get ID: “SPOT-1”, the next – “SPOT-2”, “SPOT-3”, etc… till “SPOT-20”
Typing name for each spot. If this box is checked, the systems will ask individual spot name for every
spot in the sequence. The entry will be possible with virtual alpha-numerical keypad from the main screen
each time after pressing “TEST” button. In this mode there is no global sequence name.
Sequence settings
Sequence ID - test sequence name.
Spot Qty – number of spots in the sequence. Maximum number is 99.
In order to make an entry for Sequence ID and Spot Qty , touch the area highlighted in red. The virtual
keypad will appear allowing you to enter the required information.
Proceed in the same way to call the virtual keypad in other cases.
20 Doc : AM110-001E Release: 1.2.4.4 updated : Aug2010Measurement validation. Every spot measurement in the test sequence is performed by pressing “TEST” button. In general operation mode, at the completion of a measurement the test results and spot image is displayed and remains “frozen” on the screen allowing visual check the results and the spot. The operator should press “Next>” button to validate current results and go to the next spot in the sequence. To accelerate testing there is a mode ‘Without Validation”. If the box “Without Validation” was checked at programming the test sequence, the systems will don’t ask validation of every spot measurement by pressing “Next>” button. The data will be processed, stored, transmitted to LAN and printed at single press of “TEST” button. Be careful then using this mode if the DT100 is connected to network with data processing by LIMS system. The button “
Pressing “No” allows repeating the last spot in the sequence.
Press “Yes” to terminate the test sequence.
This is necessary for proper closing the test result file in LAN or USB.
Engine correlation
Select the proper Engine Correlation for oils to be tested. This correlation is used to report Contamination
Index (IC). There are two correlations available: one for Diesel Engine lubricating oil and one for Marine
Engine lubricating oils. Use the proper correlation for the type of lubricants you are testing.
Press “Accept” to validate settings and leave the menu.
Button “Set as default” allows storing the current settings as default values. Use this button when you do
similar settings for majority of your spots. Then next time you will press the SET Sequence button the
system will set default values automatically. If there are no changes, you can just press “Accept”.
It is always possible to enter new Sequence ID and Spot Qty. If default values were set, it will valid for one
sequence only.
In order to change default settings, enter new values or delete all values and press “Set as default”.
22 Doc : AM110-001E Release: 1.2.4.4 updated : Aug2010HOW TO PERFORM A TEST
Enter the Test Sequence settings as explained above.
MEASUREMENT – GENERAL OPERATION
Enter the Test Sequence settings as explained above.
Place the paper sheet on the testing area.
Filter paper sheet can contain any number of spots. The most practical is 16 spots on the filter sheet
dimensions 260x260mm.
Caution !
For proper operation of the image processing algorithm the following requirements should be respected:
- Maximum spot diameter should not exceed 45 mm. It should be entirely in the red circle area.
- The area of minimum 50x50mm around the spot should be free of any marks or neighbor spot.
See picture below.
The instrument DT100 will illuminate the backlight lighting. Place
the first oil spot to be tested under the CCD camera and check its
positioning on the screen.
Position the filter paper to center the first spot in the programmed
sequence within the red circle shown on the display. Yellow cross
helps to align the estimated center of the spot in the center of the
testing area.
Although the DT100 image processing algorithm has no strict
requirement for perfect center alignment, the uniform orientation
of spot under the camera helps improving repeatability of results.
Because oil spots have typically non-round, oval shape it is advised
to keep the same orientation.
A spot is positioned under the camera :
23 Doc : AM110-001E Release: 1.2.4.4 updated : Aug2010When the spot is correctly positioned in the red circle, press the “TEST”
button on the touch screen or press the “Test” button on the front panel to
measure the sample.
Then the button TEST has been pressed, the DT100 instrument will do following
operations :
- Take a spot image in backlight illumination
- Analyze the image to indentify the spot edges
- Check if the spot properly positioned within the red circle.
- Process the spot image to calculate oil quality parameters : IC and MD
- Measurement results will be displayed on the left side of the image area (see section “Results
reported”). The resulting spot image is displayed and remains “frozen” on the screen allowing visual
check the results and the spot.
- Press “Next>” button on the touch screen or push one more time the “Test” button on the front
panel to validate the measurement and go to next spot. In case of doubts in results, it is possible to
redo the spot again. Press “” button signifies validation of current test result.
24 Doc : AM110-001E Release: 1.2.4.4 updated : Aug2010At this moment, depends on the result storage configuration (please refer to the section “SETTINGS” of
the present manual for more details on available storage options), the DT100 instrument will do following
operations:
- Transfer result to LAN via Ethernet link
- Store result to USB storage device
- Print result (if printer is connected and printing was requested)
After the button “Next>” been pressed, the instrument is ready to test next spot. The main screen
will keep results of the previous spot and indicate next spot position to be tested.

Position under the camera the next spot in the sequence and proceed as indicated above for the first one.
When the programmed test sequence had been completed, a blinking
message will appear: “ Sequence Completed”.
Set a new test sequence to measure the next batch of samples.
25 Doc : AM110-001E Release: 1.2.4.4 updated : Aug2010MEASUREMENT – SPECIFIC CASES
CASE 1 : “Spot is out of viewing area” message
- After pressing ‘TEST” button, the DT100 process digital image of the viewing area. If the DT100
detects that the spot is our of the circle, a message will be displayed asking to re-position the spot
and repeat the measurement
Position the spot properly and press “TEST” again.
If this message persists, it can be due to following reasons :
- The spot is not positioned correctly within red circle
- The spot diameter is big – bigger than the red circle area
- Dirt or writing marks near to the spot
Important! The reason of “Spot not detected” message could be due to presence of dirt or writing marks
in the corners of viewing area outside of the red circle. The system is using corners of viewing area to
sample the paper background image. Take care that the filter paper around of spot is clean. If not, the
spot cannot be detected properly.
In case if a spot cannot be properly tested or there is other reason to omit measurement of this spot in
test sequence, there is a possibility to skip its testing by pressing “Skip>” button on touch screen.
When “SKIP>” button was pressed:
- Spot ID number increasing
- No analyze of spot image, no measurements, no analyze if spot is within red circle
- Picture of spot is taken but not sent to LAN and not stored on USB (if programmed)

27 Doc : AM110-001E Release: 1.2.4.4 updated : Aug2010RESULTS REPORTED
Spot ID: spot identification in the sequence
Opacity: average opacity of the oil spot
MD: Dispersancy
It varies in accordance with the homogeneity of the zones and the size of
the oil spot
It is expressed by an index from 100 (ideal) to 0 (no dispersancy)
The instrument report MD value rounded to integer.
IC: Contamination Index
Measurement limits: 0.1% to 4.8 %
It is obtained with a correlation established with IFP 303 method.
DP: Overall Note
Overall Note (DP) is used for trend monitoring and gives global assessment of the oil quality.
DP value is a combination of IC and MD and it is expressed as an index from 0 (ideal) to 200+ (very poor)
The calculation is as follow: DP = (100 –MD) * IC.
Note: For DP calculation the instrument uses MD value not rounded to integer in order to increase
sensitivity of the DP value.
DI: Diameter
Calculated average spot diameter in mm.
PARTICULAR CASES OF REPORTING
Particular Case 1 – Dark spots
When the spot is too dark (opacity is lower than the defined threshold), the system will automatically
change camera exposure mode in order to get contrasted image. In that case the spot picture on the
screen will momentarily change as a fast flash. It is
normal operation of the instrument.
The camera switch allows for a better distinction
of grey levels within very dark spots. This special
mode improves correlation of Contamination
Index (IC) for heavily contaminated oils.
In case of very dark spot, the DT100 software will
display two values for OP: in normal mode and in
high exposure mode. The second value is
displayed in brackets for information only.
28 Doc : AM110-001E Release: 1.2.4.4 updated : Aug2010Particular Case 2 – Dark spot, IC is out of correlation range
If the spot is too dark and measured opacity value is over of valid range
for IC correlation, the instrument will report IC >4,8% for Diesel oil
correlation and IC >5,6% for marine oil correlation. Because the DP value
cannot be calculated in this case, the instrument will report DP = OUT.
Example of reporting for such case for diesel oil correlation is shown on
the right.
The IC value “>4.8” and DP value “OUT” will be printed, saved on USB
key and sent to LAN/LIMS.
Particular Case 3 – Indistinguishable spot
This specific case occurs when the spot opacity is very close to those of
the filter paper. The DT100 detection algorithm cannot distinguish the
spot from the background (paper).
In this specific case the software will take a default spot diameter of 20
mm. In the test report this will be indicated by an apteryx sign, as
shown on the example picture.
Important! If the system is unable to determine the spot edges, it will
take the center of the image area (cross point of yellow lines) as a spot
center. In such case, it is particularly important to properly center the spot in the red circle in order to
get repeatable results of MD and IC.
Particular Case 4 – Skipped spot in the test sequence
Running a test sequence the operator can decide to skip a doubtful spot
by pressing “SKIP>” button. In such case, all report fields will be filled
with “XX” values. These values will be printed, saved on USB key and
sent to LAN/LIMS.
29 Doc : AM110-001E Release: 1.2.4.4 updated : Aug2010Details on the image processing and calculation algorithm
Details on the image processing and calculation algorithm employed in DT100 analyzer.
The automatic measurement of oil spot by the
DT100 instrument is achieved in four steps:
1. Image processing for spot identification:
a. Search spot
b. Determine edges
c. Determine centre of the spot
d. Eliminate filter paper effects
2. The mean opacity (OP) and the mean diameter of the oil spot (DI) are calculated.
Contamination Index (IC) is determined with a correlation table based on opacity measurement.
3. The MD (Dispersancy Merit) calculation.
Dispersion characteristics of the oil are judged by how far
oil drop spreads, how big the central sooty area is and how
homogeneous the opacity of the spot is in comparison
with a theoretical reference diameter of 32mm (blue circle
on the illustration picture). The MD calculation is done in 3
steps :
a) First, homogeneity of soot distribution within the spot
is assessed by « demerit » value (not reported). The oil
spot is divided from its center in 16 concentric zones.
For each zone the average concentric opacity is
calculated. The mean concentric opacity and the opacity of each concentric zone are then
used to calculate the demerit (DB) (varies between 0 and 1).
b) The size and form of sooty area is assessed by « ratio » value (not reported. From the center
of the oil spot and on a length of 16 mm, the software calculates the sum of the light
saturation (opacity) for every pixel and determines the mean opacity. Then the software
determines the distance from the center for which the mean value of opacity is reached. With
this distance, a ratio is calculated that characterize the localization of highest soot
concentration within the spot.
c) Combination of both « demerit » and « ratio » gives the value of Dispersancy Merit (MD)
MD = (1 – DB) * (ratio * 100)
4. The DP (Overall Note) is then calculated as follow: (100 –MD) * IC.

Note : In the above example, the SPOT-4 is the skipped spot in the test sequence; the SPOT-6 is very dark
spot the IC and DP values is out of the range for correlation.
Important note 1 for LIMS data processing!
The DT100 doesn’t know at what moment the LIMS system will process result file “YYYYYY.csv” as there is
no automatic event indicating to LIMS that test sequence was completed. Thus, data processing by LIMS
system should be properly organized. Need to be very careful then using the same file name for DT100
resulting file. For example, if a Sequence ID is by default (Refer to the section “Set test sequence” ).
For example, the sequence ID is set to YYYYYY.
If YYYYYY.csv file was not processed by LIMS before the operator starts a new test sequence with the
same name, there is a risk of data lose. To reduce a risk of such error the DT100 software proceed as
following :
- When test sequence is started the DT100 creates file YYYYYY.tmp and writes test data
- When test sequence was completed (or stopped) the DT100 renames YYYYYY.tmp in YYYYYY.csv
and deletes YYYYYY.tmp
Important note 2 for LIMS data processing!
In the testing mode “Without Validation” , if a spot measurement has been repeated by pressing
“4.8 98 OUT 7 35.0

If this choice is used, the DT100 will automatically create a folder named : “DT100_MM-DD-YYYY” and
store results of the day in this folder. The results include spot images and ASCII file (csv or txt as
requested). Data of each test sequence will be added one after one.
