8.2 AC current measurement by means of analog and digital multimeters

- Set the multimeter to the function “AC current measurement” (mA AC or A

AC) and select a measurement range that can display currents from 0,5 mA

to 200 mA.

- Contact the 4 mm safety connector of the safety measuring cable with the

COM jack of the multimeter.

- Contact the red 4 mm safety connector of the safety measuring cable with

the current input jack (mA or A) of the multimeter.

- Opening lever



Operate and use meas. pliers to



clamp the single wire

live conductor.

- Read off the AC current value on the multimeter and convert to the current

value taking into account the conversion factor.

Conversion factor: 1 mA AC = 1 A AC

(see housing with label eld



)

Example:

Current value indicated on multimeter: 155 mA AC corresponds to a meas-

ured current value of 155 A AC.

8.3 AC current measurement by means of the BENNING IT 120 installation

tester

- Measurement must be carried out according to the operating manual of

the BENNING IT 120 installation tester (see chapter „TRUE RMS current

(A~)”).

- For this measurement, a conversion factor does not have to be considered.

The displayed value of the BENNING IT 120 installation tester corresponds

to the measured current value. The maximum permissible constant current

of 20 A must not be exceeded.

9. Maintenance



Before opening the BENNING CC 2, make sure that it is

disconnected from all voltages! Electrical danger!

Work on the opened BENNING CC 2 under voltage may be carried out only

by skilled electricians with special precautions for the prevention of

accidents.

Make the BENNING CC 2 voltage free as follows before opening the

instrument:

- First remove the BENNING CC 2 from the measuring object.

- Then disconnect the two safety measuring cables from the multimeter.

The clamp-on adapter BENNING CC 2 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 2 is no longer

ensured, for example in the case of:

- Visible damage of the casing.

- Incorrect measurement results.

- Recognisable consequences of prolonged storage under improper

conditions.

- Recognisable consequences of extraordinary transportation stress.

In such cases the BENNING CC 2 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. Environmental notice

At the end of the product’s useful life, please dispose of it at

appropriate collection points provided in your country.
