Calibration
All GASBOY pumps and remote dispensers are adjusted for accurate measure at the factory.
However, it is the responsibility of the installer to check the pump for accuracy, and make any
needed adjustments. Where required, it is the owner’s responsibility to report this device to the
local Weights and Measures officials for their inspection before the unit is put into service.
Each meter is equipped with a mechanism for calibration, located on the side of the meter. To
adjust the volume dispensed:
1. Check meter registration by delivering product to a reliable, accurate, 50 or 100 gallon prover.
2. Remove the seal wire from the locking pin.
3. Remove locking pin and turn wheel to adjust measurement. Turn clockwise to decrease the
amount in the prover to match the display, turn counter-clockwise to increase the amount in
the prover to match the displayed. Moving the wheel one hole position changes the
calibration by 2/3 cubic inch per 5 gallons. To change by half of this amount, you may utilize
the alternate locking pin hole on the opposing side of the calibration wheel.
4. Repeat process until volume in prover and amount recorded are within tolerance.
5. After calibration is complete, reinstall locking pin and secure in place using a seal wire.
POWER RESET EXTERNAL ADJUSTMENT
If the pump or remote dispenser fails to reset or shut off properly, the power reset may need to be
adjusted. To adjust:
1. Loosen the lock nut on adjusting screw and back screw out until it stops.
2. Move reset lever to ON position.
3. Turn adjustment screw in until reset motor starts. Advance adjustment screw an additional
½ to ¾ turn and tighten lock nut.
4. Turn reset lever to OFF, then back to ON to check proper operation. (Reset coupling should
make one revolution and stop).
