Frequently Asked Questions - CC 1 BENNING

How to use the BENNING CC 1 to measure alternating current?

Set your multimeter to AC voltage (V AC) function. Connect the black connector to the COM terminal and the red one to the V terminal of the multimeter. Open the clamp using the lever, grab a single conductor carrying current, then read the displayed voltage. Multiply by the factor 1 mV = 1 A to get the current in amperes.

What is the maximum permissible voltage relative to ground?

The maximum voltage between CC 1 outputs and ground is 600 V AC (category II) or 300 V AC (category III). Never exceed this value under risk of electric shock.

Does the BENNING CC 1 require a battery?

No, the CC 1 is a passive adapter without battery or fuse. It converts current into voltage via a Hall effect transformer (induction coil). No internal power source is required.

Which multimeters are compatible with the CC 1?

All analog or digital multimeters capable of measuring AC voltage from 1 mV to 400 mV are suitable. Ensure the input terminals accept 4 mm safety connectors.

How to interpret the displayed voltage value?

The conversion factor is 1 mV AC = 1 A AC. For example, 350 mV corresponds to 350 A. Use the 400 mV range of your multimeter for better accuracy.

Can I measure direct current (DC) with this adapter?

No, the BENNING CC 1 is designed exclusively for alternating current (AC). It cannot measure direct current.

What safety precautions should be taken?

Before each use, check the condition of the cables and clamp. Never grab a live conductor while the CC 1 is not connected to the multimeter. Avoid sources of interference. Do not open the device while live. Respect overvoltage categories.

How to clean and maintain the CC 1?

Clean the exterior with a clean, dry cloth. Do not use solvents or abrasive products. If visible damage occurs, stop use immediately and have the device serviced by a professional.

What is the measurement accuracy of the CC 1?

For frequencies 50-60 Hz: ±(1.9% + 0.5 A) from 3 A to 30 A, and ±(3.2% + 1 A) from 30 A to 400 A. Accuracy is specified at 23 °C ± 5 °C and humidity < 75%.

What to do in case of malfunction or visible damage?

Immediately put the device out of service and protect it against unintentional use. Contact a qualified electrician for inspection. Do not attempt to repair yourself unless you are competent and follow safety instructions.

• trained electrical personnel.

The BENNING CC 1 is intended for making measurements in dry environment. It must not be used for making measurements in electric circuits with a nominal voltage greater than 600 V DC/AC (for further details, see Section 6. "Environmental conditions").

The following symbols are used in these operating instructions and on the BENNING CC 1:

Application around and removal from HAZARDOUS LIVE conductors is permitted.

Warning of electrical danger! Indicates instructions which must be followed to avoid danger to persons.

Important, comply with the documentation! The symbol indicates that the information provided in the operating instructions must be complied with in order to avoid risks.

This symbol on the BENNING CC 1 means that the BENNING CC 1 is totally insulated (protection class II).

(AC) Alternating current.

2. Safety note

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 specified 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.

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 ③ Operate and use meas. pliers to ① 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 field 4)

Example:

Voltage 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:

• 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.

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.
