Calibration Procedure for Latitude Units
Units must be properly purged before calibration or calibration verification. Incomplete
purging of air can result in inaccurate calibration or errors in calibration verification
testing (normally, subsequent calibration checks will read plus). Always verify any
calibration after setting.
IMPORTANT INFORMATION
The Latitude meters are precalibrated, but calibration must be verified. Depending on the type
of unit, the procedure is slightly different. After calibration, the Weights and Measures
(W&M) switch must be seal-wired to prevent calibration tampering. Ensure that you draw the
seal wire tightly.
Latitude (Liter Unit of Measure)
Temporary pricing must be entered into the unit, as outlined in “Installation Checklists” on
page 8-1 to allow dispensing and calibration.
The currently produced Latitude uni
ts are precalibrated to Liter and programmed to default
programming values.
Note: Perform the calibration verification pr
ocedure after calibration.
