Clamp meter Benning CM 10-1 – mains and insulation testing clamp multimeter

Benning CM 10-1 – mains and insulation testing clamp multimeter is a handheld clamp-style test instrument for measuring AC current and performing essential electrical checks. The device combines non-contact current measurement with voltage and resistance testing and includes functions relevant to insulation testing, providing a compact tool for routine diagnostics of electrical circuits and loads. The instrument is intended for electricians and maintenance technicians who need quick, on-site verification of current flow, basic continuity and insulation conditions.

Advantages

The clamp design allows for current measurement without interrupting the circuit, reducing downtime during checks. Integrated voltage and resistance measurement functions enable basic troubleshooting of wiring and components. The unit’s compact form factor and straightforward controls support fast, single-handed operation in confined spaces. Built-in insulation-related functions provide an additional check on insulation integrity as part of routine maintenance and safety inspections.

Suitable for

• Measuring AC current in single conductors and cables without disconnecting them
• Quick on-site voltage checks of mains circuits
• Basic resistance and continuity testing of wiring and components
• Preliminary insulation condition checks during maintenance

Key specifications

• Clamp-type jaws for non-contact AC current measurement
• Functions for alternating voltage and resistance measurement
• Insulation-related testing functions for basic verification of insulation integrity
• Handheld, portable form factor suitable for field use
• User-friendly controls optimized for single-handed operation

How to use

Open the clamp jaws and place them around a single conductor to measure AC current without disconnecting the circuit. Select the appropriate measurement function for current, voltage or resistance on the instrument’s control dial before taking readings. For insulation-related checks, follow the model-specific procedure indicated by the device’s markings and controls; ensure the circuit is isolated and de-energized if required by the test. Read values from the display and interpret them according to applicable electrical standards and the specific needs of your diagnostic task.

Usage recommendations

Use the clamp meter only on circuits within the instrument’s specified measurement ranges and follow local safety regulations. When performing insulation-related checks, verify that any required isolation or de-energizing procedures are carried out prior to testing. Regularly inspect the clamp jaws and test leads for damage and keep the device clean and dry to ensure reliable measurements.
