isoCAL:
Automatic Calibration and Adjustment
Either 1 15 3 or 1 15 5 must be
selected in the Setup menu.
The "isoCAL" display automatically
begins flashing if the ambient
temperature has changed in relation
to the temperature at the time
of the last calibration/adjustment,
or after a defined time interval
has elapsed. The scale is telling
you that it wants to self-calibrate
and adjust.
This adjustment prompt is activated
when:
– The change in temperature
is greater than 10°C
– The scale status does not
correspond to Setup configurations
– No number or letter input is active
– The load on the load plate has
not been changed within the last
2 minutes
– The scale has not been operated
within the last 2 minutes
– The weight on the load plate may
not exceed 2% of the maximum
scale capacity
When these requirements are met,
the following symbols are displayed:
– C in the measured value line
– isoCAL in the symbol display
– G in the weight unit display
If the scale is not operated and the
load is not changed, internal
calibration and adjustment starts after
15 seconds have elapsed.
In the Setup menu, you can
configure the scale so that after
calibration and adjustment
– the application program
must be restarted
(On + reset app., 1 15 3), or
– the application program
resumes where it left off
(isoCAL on, 1 15 5)
In the Setup menu, you can also
configure the scale so that it displays
an adjustment prompt, but does
not perform the calibration and
adjustment functions automatically
(Only adj. prompt, 1 15 2)
