Close-up of a red and black G72 clamp meter with a terminal connector (no visible text or symbols on the device body)

Thank you for purchasing a G72 current clamp. This clamp should only be used only with the C.A 616X machine testers and the C.A 6424 ground tester.

For best service from your current sensor:

■ read these operating instructions carefully,

■ comply with the precautions for use.

WARNING, risk of DANGER! The operator must refer to these instructions whenever this danger symbol appears.

Application or withdrawal authorized on bare conductors carrying dangerous voltages. Type A current sensor as per IEC 61010-2-032.

The arrow indicates the direction of the current.

The product has been declared recyclable after analysis of its life cycle in accordance with the ISO 14040 standard.

Chauvin Arnoux has adopted an Eco-Design approach in designing this appliance. Analysis of the complete lifecycle has enabled us to control and optimize the effects of the product on the environment. In particular, this appliance exceeds regulation requirements with respect to recycling and reuse.

The CE marking guarantees conformity with European directives, in particular LVD and EMC.

The rubbish bin with a line through it indicates that, in the European Union, the product must undergo selective disposal in compliance with Directive WEEE 2002/96/EC. This equipment must not be treated as household waste.

Definition of measurement categories

■ Measurement category IV corresponds to measurements taken at the source of low-voltage installations.
Example: power feeders, counters and protection devices.
■ Measurement category III corresponds to measurements on building installations. Example: distribution panel, circuit-breakers, machines or fixed industrial devices.
■ Measurement category II corresponds to measurements taken on circuits directly connected to low-voltage installations.
Example: power supply to electro-domestic devices and portable tools.

This device is compliant with safety standard IEC 61010-2-032 for voltages up to 300 V in category III.

Failure to observe the safety instructions may result in electric shock, fire, explosion, or destruction of the instrument and of the installations.

■ The operator and/or the responsible authority must carefully read and clearly understand the various precautions to be taken in use. Sound knowledge and a keen awareness of electrical hazards are essential when using this instrument.
If you use this instrument other than as specified, the protection it provides may be compromised, thereby endangering you.
■ The safety of any system in which this device is incorporated is the responsibility of the system integrator.
■ Comply with the environmental conditions of use.
■ Do not use the instrument if its housing is open, deteriorated, or incorrectly reassembled. Before each use, check the integrity of the insulation of the core or of the arms of the clamps, of the housing, and of the lead. Any item of which the insulation is deteriorated (even partially) must be set aside for repair or scrapping.
■ Before using your device, check that it is perfectly dry. If it is wet, it must be thoroughly dried before being connected or being operated in any way.
■ When using the device, keep your fingers behind the physical guard.
■ Do not subject the clamp to sprayed or falling water or other liquids.
- Keep the gap of the clamp absolutely clean. Any dirt, however little, may cause the device to malfunction.
■ Use personal protection equipment systematically.
■ Any repairs must be carried out by accredited skilled personnel.

1.1. CLAMPS G72

Detachable arm. Fixed arm. Special 4-point plug. Guard. 300 V CAT III 50 A~ Arrow identifying the direction of the current. Trigger. G72 CHAUVIN® ARNOUX Shielded cord.

Current clamps are used to measure the current flowing in a cable without opening the circuit. They also insulate the user from dangerous voltages in the circuit.

The G72 clamp can measure AC leakage currents up to 50A, at the usual industrial frequencies.

It is based on the current transformer principle.

Its ergonomic shape and small size make it ideal for measurements in electrical cabinets, distribution frames, and cable assemblies.

1.2. DELIVERY CONDITION

The clamp is supplied in a cardboard box with :

■ a Velcro fastener,
■ a user manual in 5 languages,
■ a verification certificate.

2. USE

■ Connect the clamp to the current input of the tester.
■ Press the trigger on the clamp to open the jaws.

300 V CAT III 20 A - 1 300 V CAT III 20 A - 1 300 V CAT III 20 A - 1

■ Then clamp the cable that is to be measured. Where possible, the cable should be centred in the jaws of the clamp.
The arrow on the housing should point in the expected direction of current flow.
■ Release the trigger and make sure that the jaws have closed correctly.

For details of the measurement configuration and technical characteristics, refer to the user manual of the tester with which you are using the current sensor.
