The instrument is built and tested in accordance with DIN VDE 0411 part 1/ EN 61010-1 DIN VDE 0411 part 2-032/ EN 61010-2-032 DIN VDE 0411 part 031/ EN 61010-031 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. Improper handling and non-observance of the warnings might involve severe injuries or danger to life.

WARNING! Be extremely careful when working with bare con- ductors or main line carrier! Contact with live conductors will cause an electric shock!

The unit may be used only in power circuits within the over voltage category III 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 leads 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 leads 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 leads con- nectors, - insert the measurement leads in the appropriately desig- nated measuring sockets on the multimeter

8. Making measurements with the BENNING CC 3

8.1 Preparations for making measurements

Operate and store the BENNING CC 3 only at the specified storage and operat- ing temperatures. Avoid continuous insulation. - The nominal voltage and current ratings of the safety measuring leads included in the scope of delivery correspond to the ratings of the BENNING CC 3. The safety measuring lead is securely connected to the BENNING CC 3 and cannot be removed. - Check the insulation of the safety measuring leads. Discard the BENNING CC 3 immediately if the insulation is damaged. - Do not clamp the measuring pliers on a live conductor before the BENNING CC 3 has not been connected to a multimeter. - Strong sources of interference in the vicinity of the BENNING CC 3 can lead to unstable readings and measuring errors. - Do not apply any voltage to the output contacts of the BENNING CC 3.

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 3 against ground potential, is 600 V.

8.2 Direct current measurement

Select the measuring range (40 A or 300 A) by means of the sliding switch

- Set the multimeter to the function “direct voltage measurement” (V DC) 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 lead with the COM jack of the multimeter. - Contact the red 4 mm safety connector of the spiral type safety measuring lead with the voltage input jack (V) of the multimeter. - Press and hold the „ZERO“ key (null balance key)

until a measured value of approximately 0 V is displayed on the multimeter. For this purpose, close the measuring clamp

and remove it from the live conductor (external field). - Opening lever

operate and use measuring clamp

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. 40 A measuring range: 10 mV/ A 300 A measuring range: 1 mV/ A (see housing with label field

Example: Measuring range: 300 A Voltage value indicated on multimeter: 0.250 V DC = 250 mV DC, corre- sponds to a measured current value of 250 A DC. See figure 2: AC/ DC current measurement

8.3 Alternating current measurement

Select the measuring range (40 A or 300 A) by means of the sliding switch

- 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 lead with the COM jack of the multimeter. - Contact the red 4 mm safety connector of the spiral type safety measuring lead with the voltage input jack (V) of the multimeter.09/ 2016 BENNING CC 3

operate and use measuring clamp

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. 40 A measuring range: 10 mV/ A 300 A measuring range: 1 mV/ A (see housing with label field

Example: Measuring range: 300 A Voltage value indicated on multimeter: 0.250 V AC = 250 mV AC, corre- sponds to a measured current value of 250 A AC. See figure 2: AC/ DC current measurement

Before opening the BENNING CC 3, make sure that it is discon- nected from all voltages! Electrical danger! Work on the opened BENNING CC 3 under voltage may be carried out only by skilled electricians with special precautions for the prevention of accidents. Make the BENNING CC 3 voltage free as follows before opening the instrument: - First remove the BENNING CC 3 from the measuring object. - Then disconnect the two safety measuring leads from the multimeter. The BENNING CC 3 current clamp adapter is not equipped with a fuse.

9.1 Securing the instrument

Under certain circumstances safe operation of the BENNING CC 3 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 condi- tions. - Recognisable consequences of extraordinary transportation stress. In such cases the BENNING CC 3 must be disconnected from the measuring point immediately and secured to prevent further utilisation.

Clean the outside of the unit with a clean dry cloth. (Exception: any type of special cleaning cloth). Never use solvents or abrasives to clean the testing unit. Ensure that the battery compartment and the battery contacts have not been contaminated by electrolyte leakage. If any electrolyte or white deposits are seen near to the battery or in the battery compartment, remove them with a dry cloth, too.

9.3 Battery replacement

Before opening the BENNING CC 3, ensure that it is not con- nected to a source of voltage! Electrical hazard! The BENNING CC 3 is powered by 9-V block battery. Battery replacement (see figure 3) is required, if the red LED (battery indication)

lights. To replace the battery, proceed as follows: - Remove the BENNING CC 3 from the object to be measured. - Disconnect the safety measuring leads from the multimeter. - Switch the sliding switch

to position „OFF“. - Lay the BENNING CC 3 on its front and loosen the screw from the cover of the battery compartment. - Lift the battery compartment cover (at the recesses in the housing) off the bottom part. - Lift the discharged battery out of the battery compartment and remove the battery leads carefully from the battery. - Connect the new battery with the battery leads and arrange them in such a way that they are not crushed between the two halves of the housing. Then place the battery in the correct position in the battery compartment. - Clip the battery cover onto the bottom part and tighten the screw. See fig. 3: Battery replacement09/ 2016 BENNING CC 3

Remember the environment! Do not dispose of used batteries with domestic waste. Dispose of them at a battery-collection point or as toxic waste. Your local authority will give you the information you need.

Benning guarantees compliance with the technical and accuracy specifications stated in the operating manual for the first 12 months after the delivery date.
