Calculating the Calibration Factor
Use the following tables and formulas to calculate the change to make to the calibration factor.
Example of Calibration Factor Change
Dispense until the display reads 1 liter (1000 ml) into a clean, calibrated, volumetric measuring flask. For increased
accuracy, submerge the nozzle, and let the air settle out of the fluid for ten minutes before you note the volume. In
this example, reading the flask shows the volume to be 11 ml less than 1000 ml. See the left column of the
Metric
Measurement table below, and find the number closest to –11, which is –9,34. Look for the corresponding number
in the right column, which is –17. Thus, the calibration factor should change by –17. If the current calibration factor
is 6815, subtract 17 to get the new calibration factor of 6798, and change 6815 to 6798. See
Calibrating the
Meter on page 13 for instructions on changing the calibration factor.

Formulas:
If the dispensed amount according to the markings on
the flask is greater than the displayed amount:
New CF = Old CF + (Error in
cm

/ 0,555)
If the dispensed amount according to the markings on
the flask is less than the displayed amount:
New CF = Old CF – (Error in

3
/ 0,555)
where:
CF = calibration factor
0,555 = constant
