NOTE: To prevent gross miscalculation, the meter
rejects numbers outside the following calibration
ranges, and displays the previously stored calibration
factor. Pressing TOTAL will zero the display and allow
you to perform the calibration dispense again.
After dispensing, the displayed number is the
new calibration factor. The new calibration
factor must be within 20 percent of the
factory default value [in the range of 294–442
quarts (310–467 liters)], or it will not be
accepted.
The following table lists approximate
calibration factors for different fluids. Your
calibration number may vary slightly due to
temperature or flow rate.
