Calibration and Adjustment

Purpose
To check the accuracy of the weighing
instrument and perform any adjustment
required.
Calibration determines the difference
between the value displayed and the
actual weight on the platform.
Calibration does not entail making
any changes within the weighing
instrument.
The adjustment procedure actually
eliminates the difference between the
readout and the actual weight,
or reduces it to a level within the
permissible tolerance limits.
Example
External calibration and manual adjustment with default weights
Settings in the Setup menu:
1.9.1; 1.10.2

Features
Which of the following features are
available depends on the weighing
platform:
– External calibration/adjustment with
the default weight value or standard
weight (1.9.1) (not available on verified
scales)
– External calibration/adjustment with
a user-defined weight (1.9.3) (not
available on verified scales)
– Block the J key to prevent use of the
two functions described above (1.9.10)
– Calibrate first; then adjust automatically
(1.10.1) (not available on verified
instruments)
– Calibrate, then prompt for manual
input of adjustment command (1.10.2)
– Display of calibration prompt: flashing
W symbol (1.15.2).
– Block external calibration/adjustment
(1.16.2)
Unload and zero the scale
Start calibration; e.g., when calibration prompt (W) is flashing
The "Calibration: External, default weights" menu item is displayed for 2 seconds...
...after which you are prompted to place the required weight on the platform (e.g., 10 kg)
– Display altitude and geographical
latitude or acceleration of gravity after
CAL is shown at the beginning of the
calibration procedure (menu item
8.12.2). These values are shown only
if they have been entered in the service
menu and activated.
For each of these parameters, the term
is displayed first ("Altitud," "Latitud" or
"Gravity") for 1 second, and then the
corresponding value is displayed con-
tinuously until you press ).
Note
On verified weighing instruments,
the external calibration/adjustment
function is available only when the
menu access switch is in the "open"
position, which entails breaking the
verification seal. The equipment must
be re-verified after the seal has been
broken.
