The instrument is built and tested in accordance with DIN VDE 0411 part 1/ EN 61010-1 and has left the factory in perfectly safe technical state. To maintain this state and ensure safe operation of the appliance tester, the user must observe the notes and warnings given in these instructions at all times.

The unit may be used only in power circuits within the over voltage category III with a conductor for 300 V max. to earth or over voltage category II with a conductor for 600 V max. to earth. Remember that work on electrical components of all kinds is dangerous. Even low voltages of 30 V AC and 60 V DC may be dangerous to human life.

Before starting the appliance tester up, always check it as well as all cables and wires for signs of damage. Should it appear that safe operation of the appliance tester is no longer possible, it should be shut down immediately and secured to prevent it being switched on accidentally. It may be assumed that safe operation is no longer possible:

if the instrument or the measuring cables show visible signs of damage, or - if the appliance tester no longer functions, or - after long periods of storage under unfavourable conditions, or - after being subjected to rough transport.

In order to avoid danger, - do not touch the bare prod tips of the measuring cables connectors, - insert the measurement lines in the appropriately designated measuring sockets on the multimeter

8. Making measurements with the BENNING CC 1

8.1 Preparations for making measurements

Operate and store the BENNING CC 1 only at the specied storage and operating temperatures. Avoid continuous insulation. - The nominal voltage and current ratings of the safety measuring cables included in the scope of delivery correspond to the ratings of the BENNING CC 1. - The safety measuring cable is securely connected to the BENNING CC 1 and cannot be removed. - Check the insulation of the safety measuring cables. Discard the BENNING CC 1 immediately if the insulation is damaged. - Do not clamp the measuring pliers on a live conductor before the BENNING CC 1 has not been connected to a multimeter. Strong sources of interference in the vicinity of the BENNING CC 1 can lead to unstable readings and measuring errors. - Do not apply any voltage to the output contacts of the BENNING CC 1.

Do not exceed the maximum permitted voltage with respect to earth potential! Electrical danger! The highest voltage, that may be applied to the BENNING CC 1 against ground potential, is 600 V. 12/ 2005

8.2 Alternating current measurement

- Set 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. - Contact the 4 mm safety connector of the spiral type safety measuring cable with the COM jack of the multimeter. - Contact the red 4 mm safety connector of the spiral type safety measuring cable with the voltage input jack (V) of the multimeter. - Opening lever

Operate and use meas. pliers to

clamp the single wire live conductor. - Read 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 eld

Example: Voltage value indicated on multimeter: 0.350 V AC = 350 mV AC, corresponds to a measured current value of 350 A AC.

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: - 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 1 must be disconnected from the measuring point immediately and secured to prevent further utilisation.

Clean the casing externally with a clean dry cloth (exception: special cleaning wipers). Avoid using solvents and/or scouring agents for cleaning the instrument.
