Testing and calibration
To ensure reliable results it is advised to check balance accuracy with an object of
precisely known weight before and after each measuring session.
To check a balance with EC verification use a weight standard as stated in
Technical Data table for specific balance type (or of better accuracy) with valid
calibration certificates. In case permissible error is exceeded please contact an
authorised service.

External calibration / calibration options
Calibration with external weight standard in verified balances should be performed
in case balance indications exceed permissible error. To calibrate the balance
a service centre should use calibration weight as stated in Technical Data table (or
of better accuracy) with valid calibration certificate.
External calibration in verified balance should be performed in
authorised PCE services, as it is possible only after removing protective
seals. In this case the validity of the verification is void and the balance
must be re-verified by the nearest Notified Body or at the place of
installation.
In balances with EC verification calibration function is blocked for the user. It is
only possible to print calibration report useful for routine balance check-through.
The report printout example
- internal weight value registered during
factory calibration
,
- internal weight value registered during
last calibration ,
- difference between internal weight
values: factory value–current value
(PCE-ABZ 200C diosis).
