2.6.1 Seal the Indicator
For access to configuration parameters, the setup switch must be pressed.
Allows Service Access
The calibration cover is used for inserting a lead wire seal through both fillister screws and the plastic cover. The
cover allows access to the electronics and electrical contacts, while preventing access into Legal for Trade
configuration parameters.
There is an alternative cover over the A/D to ensure the A/D and load cell connection cannot be changed after the
unit is sealed.
There is also an audit trail counter to track calibration and configuration changes made to legally relevant
parameters.
Place the Calibration Cover on the backplate and secure with the existing fillister head screws and o-rings to seal
the indicator for Legal for Trade approval.

Prevents Service Access

electronics, electrical contacts, and Legal for Trade configuration parameters.
