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 (-1.2 ounces). See the left column
and find the number closest to -1.2 ounce value which is 1.0.

• 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.
