To begin the calibration process, you must first put the LCR.iQ into the calibration mode by
removing any existing seal wire and loosening the calibration bolt on the side of the register
housing approximately 5-6 turns. If a ticket printer is connected to the LCR.iQ, make sure a
ticket is in place and the printer is ready. If connected, the register will print a calibration ticket
showing the current calibration information of the register. If no ticket printer is connected or
the calibration ticket is not desired, press the
Abort
key to skip the print process.
Once in the calibration mode, select the calibration option from the main menu to access the
calibration screens. If this is the first calibration for the register or if the calibration factor
(Pulse/Unit) has not been set for the meter that the register is connected to, it is recommend
to set a starting factor. This will save time and additional calibration runs as the register
adjusts the meters accuracy closer to zero error. See the recommended starting calibration
factor chart in the appendix of this manual for typical starting calibration factors and enter this
value in the Pulse/Unit field.
NOTE:
Unit label will vary depending on the unit of measure that has
been set up in the LCR.iQ.
In the calibration screens you will notice that there is a yellow key labeled
Run
Calibration
.
Pressing this key will begin the actual calibration process by performing the meter screen test
and resetting the delivery volume to 000.000. At the same time, the LCR.iQ will provide the
permissive signal to the valve output to allow flow through the meter.
NOTE:
All deliveries in the calibration mode have a resolution to the
thousandths decimal place allowing for very precise calibration.
Flow product into or through the proving device at the normal (nominal) operating flow rate for
the meter until the desired calibration volume is reached. When calibrating the flow meter, it is
recommended that the calibration volume be greater than or equal to the high end flow rate
rating of the metering device (100 GPM = Minimum 100 Gallon prover).
Once the desired calibration volume is reached, pressing the
End
button will return the LCR.iQ
back to the calibration menu screens. Navigate the selection bar to the
Prover
quantity field,
and press
OK
. Enter the exact volume to the greatest detail that was registered on the proving
