Internal Calibration/Adjustment
The menu code setting
1 9 4
must be
selected in the Setup menu.
Inside the balance housing is a built-in,
motorized calibration weight.
The internal calibration/adjustment
sequence is as follows:
G
Select the calibration function:
Press
q
> The internal calibration weight is
applied automatically
> The balance is calibrated
> If the setting for “Calibration automati-
cally followed by adjustment” (
1 10 1
)
is selected in the Setup menu, the bal-
ance is now automatically adjusted
> The internal calibration weight is
removed
Calibration and Adjustment Sequence
In the Setup menu, you can configure
the balance so that:
– calibration is always followed automati-
cally by adjustment
(
cal. -> auto adjust, 1 10 1
), or
– you have the choice of ending the
sequence or starting adjustment after
calibration
(
cal. -> man. adjust, 1 10 2
).
If no deviation is determined during
calibration, or the deviation is within
the tolerance limits dictated by the
degree of accuracy you require, it is not
necessary to adjust the balance. In this
case, you can end the
calibration/adjustment sequence after
calibration. There are 2 soft keys active
at this point:
–
ext. adjust
or
int. adjust
to start adjustment
–
end
to end the sequence
isoCAL:
Automatic Calibration and Adjustment
Either
1 15 3
or
1 15 5
must be select-
ed in the Setup menu.
The “isoCAL” display automatically
begins flashing if the ambient tempera-
ture has changed in relation to the tem-
perature at the time of the last calibra-
tion/adjustment, or after a defined time
interval has elapsed. The balance is
telling you that it wants to self-cali-
brate and adjust.
This adjustment prompt is activated
when:
– The change in temperature or the
elapsed time interval is greater than
that shown in the table below
– The balance status does not correspond
to Setup configurations
– No number or letter input is active
– The load on the pan has not been
changed within the last 2 minutes
– The balance has not been operated
within the last 2 minutes
– The weight on the pan must be no
more than 2% at the most of the maxi-
mum capacity of the balance
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 balance 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 balance 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 con-
figure the balance so that it displays an
adjustment prompt,
but does not perform the
calibration/functions automatically
(
Only adj. prompt,
1 15 2
)
