Start-Up and Test
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 counterclockwise 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 can utilize the alternate
locking pin hole on the opposing side of the calibration wheel.
4 Repeat the 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.
9850Q and 9850QE Models
1 Check meter registration by delivering product to a reliable, accurate, 50 or 100 gallon prover.
2 Convert the amount of the error to gallons per 100 (which gives a percent figure) or gallons
per thousand (which gives tenths of a percent figure).
3 Read the setting indicated on the adjuster. The amount of the error is added to or subtracted
from this setting. The adjuster is shown in graduated divisions of 1%, 0.1%, 0.02%.
4 Reset the adjuster by loosening the clamp.
• To decrease the amount delivered, turn the thimble IN on the barrel.
• To increase the amount delivered, turn the thimble OUT (unscrew it). After resetting the
adjuster, tighten clamp.
