Calibration Interval - Unitest BEHA CHB 5 Bedienungsanleitung

If the symbol for Low-battery appears in the upper left corner of the display, the
battery must be changed.
This is carried out as follows:
1) Separate the Meterman Current Clamp AC50 from any circuit, and remove the test
leads.
2) Switch the instrument off
3) Open the housing by removing the 3 screws on the rear face.
4) Remove the old batteries
5) Fit the new batteries (2 type 1.5 V IEC LR6), taking care that the polarity is correct.
Make sure that no wires are trapped between the 2 halves of the housing, and close
it again.
6) The instrument is now ready for further use.
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 regarding the return, recycling
and disposal of used batteries.
If an instrument is not used over an extended time period, the 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.

Calibration Interval

We suggest a calibration interval of one year. If the instrument is used very often or if it
is used under rough conditions we recommend shorter intervals. If the instrument is used
only a few times a year, the calibration interval can be extended to 3 years.
