Calibration Interval - Unitest CHB 3 Bedienungsanleitung

Please consider your environment when you dispose of
your one-way batteries or accumulators. They belong in
a rubbish dump for hazardous waste. In most cases, the
batteries can be returned to their point of sale.
Please, comply with the respective valid regulation re-
garding the return, recycling and disposal of used bat-
teries and accumulators.
If an instrument is not used over an extended time pe-
riod, the accumulators or batteries must be removed.
Should the instrument be contaminated by leaking
battery cells, the instrument has to be returned for
cleaning and inspection to the factory.

The instrument has to be periodically calibrated by our serv-
ice department in order to ensure the specified accuracy of
measurement results. We recommend a calibration interval
of one year.
