Scale menu.
The "isoCAL" display automatically
begins flashing if the ambient
temperature changes 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
adjust itself.
This automatic calibration prompt
is triggered when:
– The change in temperature is
greater than 10 Kelvin
– The scale status does
not correspond to Setup
configurations
– No number or letter input
is active
– The load has not been changed
within the last 2 minutes
– The scale has not been operated
within the last 2 minutes
– The load on the scale does
not exceed 2% of the maximum
capacity
When these requirements are met,
is displayed in the measured
C
value line.
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: Input menu, you can
now enter up to three different times
of day for automatic calibration/
adjustment. The scale will display
the flashing calibration prompt
("isoCAL"). Calibration/adjustment
is not performed if the scale is off
or in the Setup mode at the time set
for calibration.
If the scale is being operated at the
time set for automatic calibration/
adjustment, the calibration/
adjustment sequence is prompted
afterward.
If time settings are selected for
automatic calibration/adjustment,
the time and temperature criteria
for the isoCAL function are switched
off.
Automatic calibration/adjustment is
prompted at fixed times when:
– The user-defined time is reached
– The scale status does not
correspond to Setup configurations
– No alphanumeric input is active
(e.g., equation for calculation)
– The load has not been changed
within the last 2 minutes
– The scale has not been operated
within the last 2 minutes
– The load on the scale does
not exceed 2% of the maximum
capacity
When these requirements are met,
is displayed in the measured
C
value line.
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
or
On
is restarted
On and reset

the app.
Also in Setup, you can configure
the scale so that it displays
a calibration prompt, but does not
perform the calibration/adjustment
functions automatically
