6. Maintenance and calibration
6.1 Calibration
Like any other test instrument, the UNIMET
®
300ST requires a regular measured values check. The
calibration interval is 36 months. The test system can only be calibrated and adjusted by Bender or
a centre approved by Bender.
6.2 Changing the battery
The UNIMET
®
300ST clock is powered by a battery with a battery life of approximately four years (see
also chapter "4.5.5 Time/date"). If the battery voltage is too low, the following message appears after
switching on the test system:
The test system battery can only be changed by Bender or a centre approved by Bender.
The battery is always replaced by Bender as part of the calibration procedure.
6.3 Error messages
The UNIMET
®
300ST continuously monitors its device functions. In the unlikely event on an error
occurring, a message will appear on the display:
xxxxxx stands for the type of error given out. There are the following different types of errors:
Type of fault
Meaning
I2C bus (Code 002)

Errors in memory for the calibration values. In certain cases,
can be eliminated by correcting the calibration values in the
UNIMET® 300ST database
