3.3.3. Adding a Calibration Point (continued)
Use the following procedure to add a calibration point to the DMC.
1. Navigate to the sub-menu for the calibration point to be added. Use menu address 2.1
for ‘CUTCAL1’, menu address 2.2 for ‘CUTCAL2’ or menu address 2.3 for ‘MLTICAL’
and enter the sub-menu.
a. NOTE: the ‘X’ in the following menu address would be determined based on the
calibration point being calibrated.
2. Store the required calibration data into the DCM by selecting the “STORE” function
at menu item 2.X.1 and change the value from ‘NO’ to ‘YES’ and accept the change by
pressing ‘ENTER’.
a. This stores all the required calibration information into the DCM.
3. Retrieve a sample of the oil being processed and perform a ‘Water Content Test’ to
determine the true percentage of water in the process flow.
a. The sample should be collected at the same time that step 2 was completed.
This ensures the stored calibration data is representative of the collected sample.
b. Either a centripetal or titration testing methods can be used. Which method to
use is generally indicated by the site managing contractor.
4. Once the true water content of the collected sample is determined, store the actual
water percent into the DCM by selecting the “ACT CAL” function at menu item 2.X.2.
Enter the actual water percent of the sample and accept the change by pressing ‘ENTER’.
a. This completes the calibration process.
5. Press and hold the ‘BACK’ button for 5 seconds to return to the meter display.
a. The H2O cut should read the entered water cut percentage.

3.3.4. Clearing a Calibration Point
User calibration data can be cleared and reset to default values for either calibration
points 1 and 2 as well as all multi point calibration data. This data is independently reset
through a dedicated menu in each of the ‘CUTCAL1’ (menu address 2.1), ‘CUTCAL2’
(menu address 2.2), or ‘MLTCAL’ (menu address 2.3) menus.
To clear the user calibration data, complete the following procedure.
1. Navigate to the sub-menu for the calibration data to be cleared. Use menu address
2.1 for ‘CUTCAL1’, menu address 2.2 for ‘CUTCAL2’ or menu address 2.3 for ‘MLTCAL’
and enter the sub-menu.
a. NOTE: the ‘X’ in the following menu address would be determined based on the
calibration data to be cleared.
2. Clear the calibration data in the DCM by selecting the “CLEAR” function at menu
item ‘2.X.3’ and change the value from ‘NO’ to ‘YES’ and accept the change by pressing
‘ENTER’.
a. This clears the calibration information in the DCM.
3. Press and hold the ‘BACK’ button for 5 seconds to return to the meter display.
