“isoCAL” Self-Calibrating Function
A balance of the Master Series can self-calibrate.
The self-calibrating function is activated based on the following parameters:

These parameters are the same for the corresponding balance/scale models
that have been verified or are acceptable for legal metrological verification (models
AC/LC…-0CEMS).
In addition, the self-calibrating function is activated after an hour has passed
since the balance was connected to AC power (power on) and after an hour has
passed since the time was set.
If the balance self-calibrates due to a change in temperature, the timer for the
calibration interval is set back to zero. The timer for the calibration interval is also
active when the balance is in the standby mode. After the balance has been
turned on, a check is run to see if a calibration time was exceeded while the
balance was in the standby mode.
Flashing
W
Symbol
If the “
W
” symbol flashes, the balance wants to self-calibrate. You do not need to
interrupt your weighing series, because the balance will wait until you have
unloaded the weighing pan (at least to approx. 2% of maximum capacity) and
have not used the balance for two minutes. Then the balance will self-calibrate.
The
W
symbol flashes until the balance begins self-calibration or until you activate
the calibration function manually (see also “Calibration” in Part 1).
You can interrupt the calibration process at any time by pressing the
c
key.
If any external disturbance affects self-calibration, the error code “Err 03”
will be displayed, and the procedure will be interrupted by two beep tones.
After two minutes, the self-calibrating function will restart.
