4.4.2. Calibration and Configuration Counters
Within the instrument there are a number of trade critical registers that can affect
the calibration and/or legal for trade performance of the instrument. If any of these
registers are altered, the trade certification of the scale will be voided.
The instrument provides built-in calibration counters to monitor the number of times
the critical registers are altered. The value of the counter is stored within the unit
and can only be reset at the factory. Each time a critical register is altered, the
counter will increase. Whenever the instrument is powered up, or setup mode is
entered/exited, the current value in the counter is displayed briefly (eg. C00010).
Note: When the Scale Use is set to NTEP two counters will display. The table
below describes when the counter(s) will increment for Industrial, OIML or NTEP
modes.

The Calibration Counter
increments when trade critical
settings in the Calibration (CAL)
menu, marked with ⊗
⊗⊗
⊗, are changed.
An example of the counter is
C.00010.
The Configuration Counter
increments when other trade critical
settings (ie. not in the CAL menu),
marked with ⊗
⊗⊗
⊗, are changed. An
example of the counter is F.00009.
Internally, the instrument operates with two counters - the Calibration Counter
(REG_CAL_COUNT_NTEP) and the Configuration Counter
(REG_CFG_COUNT_NTEP). These correspond directly to the NTEP counters.
The Industrial/OIML Calibration Counter (REG_CAL_COUNT_OIML) is the sum of
these NTEP counters. Each register has a bit in the Permission property to indicate
if a counter will be incremented when the register’s value is modified. This counter
is incremented even if the values are not saved to EEPROM.
The Calibration counter is incremented for trade critical registers that affect
calibration parameters. The Configuration counter is incremented for trade critical
registers that affect configuration parameters.
The value(s) of the counter(s) 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 a legal for trade
critical settings.
