Safety

The UNITEST Clamp Meter CHB 5 has been manufactured and tested to comply
with the safety regulations for electronic measuring equipment contained in DIN
VDE 0411 and EN 61010, and left our works in a safe condition.To maintain this con-
dition, the user must observe the safety instructions contained in this Instruction
Manual.
To avoid electric shock, safety measures must be observed when working
with voltages higher than 120 V (60 V) DC or 50 V (25 V) RMS AC. These are
the values of threshold contact voltages given by DIN VDE. The values in brak-
kets apply to medical and agricultural applications.
Before each measurement make sure that the test leads and the instrument
are undamaged.
Only handle test leads and probes on the grips provided. Avoid touching pro-
bes under any circumstances.
The relevant safety regulations for electrical plant and equipment must be ob-
served during all operations.
The instrument must only be used in the specified ranges.
Before opening the instrument, it must be disconnected from all circuits.
Protect the instrument from prolonged exposure to direct sunlight.

The instrument may only be used under those conditions and for those pur-
poses for which it was conceived. For this reason, in particular the safety re-
ferences, the technical data including environmental conditions and the

When modifying or changing the instrument, the operational safety is no lon-
ger ensured.
The instrument may only be opened by an authorised service technician, e.g.
