Multiple Presets
For applications in which you have an initial preset volume, but the final preset volume has not
been determined, it is best to use the multiple preset option. Multiple preset allows the user to
set a preset amount. However, once the preset is reached, the delivery is paused, not
completed. This allows the user to either add more fuel on top of the preset amount or set
another preset amount for the remaining amount. This process can be repeated over again
until such time that a final amount is determined. Once the final amount is determined, the
user issues the end of delivery command by pressing the
End
/
key terminating the
delivery. At this time, the preset amount is set back to zero and the user must set a new
preset amount, if desired, for the next delivery.
Using the hose reset feature
The hose reset feature is a Weights and Measures requirement that allows the user a one-
time reset of the register back to zero after a delivery is started in order to charge the hose
with system pressure. This assumes that the amount to charge the hose is within the hose
reset features limits. The reason this feature is permitted, is that following a preset delivery,
the meters preset valve (on the outlet of the meter) closes once the preset amount is reached,
yet the fueling nozzle at the end of the hose is still open. This causes a small void in the
packing of the hose because of the loss of system pressure.
To use this feature, start a delivery on the LCR.iQ and engage the pump (apply system
pressure)–while leaving the nozzle closed. If the meter jumps up a few tenth of a unit, this is
because there was a void in the hose that has now been filled by adding the pump pressure. If
the amount is less than 1 gallon (or 4 Liters), the user is able to reset the register back to zero
by pressing the
Stop
key, followed by the
Hose
Reset
key. At this time, the register will be
reading zero again and by pressing the
Resume
key, the user can continue with normal
delivery functions.
Single-point Calibration
Single-point calibration of the LCR.iQ is designed to be quick and easy. Calibration of the
LCR.iQ should be performed by a qualified Weights and Measures authorized or factory
trained technician. Typical calibrations are done using a volumetric prover, master meter or
inline SVP (Small Volume Prover). Ensure that all equipment is properly connected and lines
fully charged (pressurized) between the meter and proving device.
