Quantium 110 & 210 Installation Manual Commissioning
Document Ref 947571-001 Rev 2 Page 6-3
•Test the meters are within the legal requirements:-
- Lift each nozzle and deliver approximately 20 litres into a Tokheim
approved calibrated container until all air and fuel substitute has been expelled
through the nozzle and/or air vent pipes.
Note : Discard this filling since it will contain fuel substitute from the
dispenser pipes and components and air from the supply pipes.
IMPORTANT : DISCARD ALL TEST FILLINGS SAFELY.
•Perform a test filling into the calibrated container until 20 litres have been
dispensed according to the calculator display.
•Read the measurement on the calibrated container.
If the fuel dispensed into the container is above or below the calibration line (i.e.
greater or less than the 20 litres dispensed) then the meter must be adjusted to
ensure Weights & Measures (W&M) compliance.
Note : W&M regulations vary according to different countries.
6.2 Calibration of the Dispenser
If the meter is fitted with an enhanced pulser for electronic calibration (MPE-EC) or
temperature compensation (MPE-TC) then it should not be necessary to perform mechanical
calibration. Refer to section 6.2.2 to perform electronic calibration.
MID CERTIFIED DISPENSERS
MID certified dispensers are calibrated in the factory with the relevant seals stamped so it
can be put into operation immediately upon installation without Weights & Measures
verification. Refer to section 1.7 for the identification of MID dispensers.
A calibration check should be performed as part of the Commissioning procedure. If the
calibration is outwith legal tolerances, the factory MID verification is invalidated. The
meter should be adjusted accordingly then a local National verification will need to be
performed before the dispenser can be used.
6.2.1 MECHANICAL CALIBRATION OF THE METER
•Carefully remove the W&M seal on the bottom of
the meter.
Note : Store the seal in a safe place for re-use.
•Use a small screwdriver to adjust the calibration on
the meter.
Note : each notch on the meter corresponds to
approximately 20ml.
•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.
•Re-test the dispenser until calibration is within acceptable tolerance levels.
•Replace the W&M seals to the bottom of the adjusted meter(s).
