Battery Replacement - Benning CC 3 Instrucciones De Servicio

- 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:
300 A measuring range: 1 mV/ A
(see housing with label field 8 )
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.

9. Maintenance

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.
9.2 Cleaning
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) 6 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.
