11.5. Calibration Counter
Within Setup there are a number of critical steps that can affect the calibration
and/or legal for trade performance of the instrument. If any of these steps are
altered, the trade certification of the scale could be voided.
The instrument
provides built-in calibration counter(s) to monitor the number of
times the critical steps are altered. The value of a counter is stored within the
instrument and can only be reset at the factory. Each time a critical step is altered,
the counter will increase by one. Whenever the instrument is powered up, or setup
mode is entered/exited, the current value in the counter is displayed briefly (eg.
C00010).
The value of the counter is written on the tamperproof trade label on the front of the
indicator for trade-certified applications and functions as an electronic seal. If any
legal for trade settings are changed on the instrument, the current value of the
calibration counter will be different from the recorded value and the seal is broken.
In this manual, items marked with
indicate that the setting is legal for trade critical
settings.
11.6. Passcodes
The instrument has three levels of passcode to provide security for instrument
functions, calibration and general configuration.
Full Setup Passcode
Safe Setup Passcode
Operator Passcode
The Full Setup passcode can also be used to access Safe Setup and Operator
functions.
Instrument settings that are accessed by the communications are protected by the
same passcodes.
