Commissioning Quantium 510 Installation Manual
6.2.1 MECHANICAL CALIBRATION OF THE METER
•Carefully remove the W&M seal on the meter.
•Use a TX30 bit to remove the hexalobular screw on
the plastic protective cover on the meter.
•Use a 10mm spanner to calibrate the piston meter by
turning BOTH adjustment screws.
Note : If the error is greater than 0.05% then balance the error by adjusting
both screws equally.
•Adjust in a clockwise direction to reduce the amount of fuel delivered i.e. if the
fuel in the container is greater than the reading on the calculator display.
•Adjust in an anti-clockwise direction to increase the amount of fuel delivered
i.e. if the fuel in the container is less than the reading on the calculator display.
Note : each “click” per adjustment screw corresponds to approximately
0.05% or 10ml.
•Re-test the dispenser until calibration is within acceptable tolerance levels.
•Replace the W&M seals to the adjusted meter.
