8.2 Alternating current measurement
- S et the multimeter to the function "alternating voltage measurement" (V AC)
and select a measurement range that can display voltages from 1 mV to
400 mV.
- C ontact the 4 mm safety connector of the spiral type safety measuring cable

live conductor.
- R ead off the voltage value on the multimeter and convert to the current
value taking into account the conversion factor.
Conversion factor: 1 mV AC = 1 A AC
(see housing with label field  )
Example:
V oltage value indicated on multimeter: 0.350 V AC = 350 mV AC,
corresponds to a measured current value of 350 A AC.
9. Maintenance

Before opening the BENNING CC 1, make sure that it is
disconnected from all voltages! Electrical danger!
Work on the opened BENNING CC 1 under voltage may be carried out
only by skilled electricians with special precautions for the prevention of
accidents.
Make the BENNING CC 1 voltage free as follows before opening the
instrument:
- First remove the BENNING CC 1 from the measuring object.
- Then disconnect the two safety measuring cables from the multimeter.
The clamp-on adapter BENNING CC 1 has neither a battery nor a fuse so that
as a rule it does not need to be opened.
9.1 Securing the instrument
Under certain circumstances safe operation of the BENNING CC 1 is no longer
ensured, for example in the case of:
- V isible damage of the casing.
- I ncorrect measurement results.
- R ecognisable consequences of prolonged storage under improper
conditions.
- R ecognisable consequences of extraordinary transportation stress.
In such cases the BENNING CC 1 must be disconnected from the measuring
point immediately and secured to prevent further utilisation.
9.2 Cleaning
Clean the casing externally with a clean dry cloth (exception: special cleaning
wipers). Avoid using solvents and/or scouring agents for cleaning the
instrument.
10. E nvironmental notice
