Lap Pad Calibration & Set-Up
• Make sure that the Lap Pad or other dat a entry device is connected to the LCR register as described in the LCR
Installation Manual.
• When proving the LCR system, follow the pre-test and inspection procedures established by Weights & Measures
authorities. The primary indicating and recording element on a vehicle-mounted LCR is the 6-digit liquid cryst al
display.
• Weights & Measures inspectors are responsible for determining if the truck metering and recording element s of the
system are within tolerance. To make this determination, the system should be tested under normal conditions.
• The LCR is pre-programmed with common values for many of the programmable p arameters. These values should
be checked to ensure that they fit the specific requirement s of the given inst allation. Detailed instructions for
checking and changing these values follow later in this publication.
• Changes cannot be made to metrologically significant dat a without first removing the Switchplate and it s associ-
ated Weights & Measures seal. The security level for each of the programming screens is defined in the following
table:
STEP 1: REMOVE THE LCR
SWITCHPLATE
• Remove the lead seal and wire assembly from the
LCR Switchplate (if previously sealed by Weights &
Measures authorities).
• Remove the four screws that secure the Switch Plate
over the red Selector Switch located on the front of
the LCR, and remove the plate.
• Rotate the Selector Switch counter clockwise to the
6 o'clock (CALIBRATION) position to permit access
to all programming fields (except FACTORY).
NOTE
