Readout in TOTAL VOLUME is the new METER CAL number. This number should be within
+/- 3% of the calibration number stamped on the tag of the Flow Meter.

before
retesting).

To verify Flow Meter calibration, fill applicator tank with a predetermined amount
of measured liquid (i.e. 250 gallons). DO NOT RELY ON GRADUATION NUMBERS MOLDED
