Calculating the Calibration Factor
Calculating the Calibration Factor
Use the following tables and formulas to calculate the change to the calibration factor.
Example of Calibration Adjustment for Motor Oil (quarts - 368)
Dispense into a clean, calibrated, volumetric measuring flask until the meter display indicates 1 quart of fluid has been dispensed.
For greater accuracy, submerge the nozzle and let the air settle out of the fluid for ten minutes before noting the volume.
•In the following example, the flask shows the volume is less than one quart
•Look for the corresponding number in the right column, which is +12. If the current calibration factor is 368, add 12 to get the new calibration factor of 380.
•Change this factor for a fluid in Tank Setup and for given meter(s) in Meter Setup.

The table on the right lists approximate calibration fac- tors for different fluids. Your calibration number may vary slightly due to temperature or flow rate.
