Clamp multimeter Benning CM P2 10 mA–400 A AC/DC TRMS with batteries, test leads and carrying case

Benning CM P2 is a clamp multimeter engineered for accurate AC and DC current measurement across a range of 10 mA to 400 A using true-RMS (TRMS) sensing. Supplied with batteries, insulated test leads and a protective carrying case, the instrument is configured for portable onsite diagnostics and routine electrical maintenance. The compact clamp jaw and clear display enable quick current checks on conductors without disconnecting circuits, while the TRMS function ensures reliable readings on non-sinusoidal and distorted waveforms.

Advantages

The device combines a wide current measurement range with TRMS accuracy to handle both small leakage currents and high load currents. Included accessories—batteries, test leads and a carrying case—allow immediate use and safe transport. The clamp design permits non-invasive measurements and reduces downtime during installation, troubleshooting and service tasks. Its construction focuses on practical field use with straightforward controls and robust handling.

Suitable for

• Troubleshooting electrical circuits and identifying overloads
• Measuring currents in motors, pumps and industrial equipment
• Verifying power distribution and load balancing in electrical panels
• Maintenance checks in building services, HVAC and electrical installations
• Field service work where portable, non-contact current measurement is needed

Key specifications

• Measurement type: AC and DC current with true-RMS sensing
• Current range: 10 mA to 400 A
• Power supply: supplied batteries for immediate operation
• Accessories included: insulated test leads and carrying case
• Form factor: clamp jaw for non-contact conductor measurement

How to use

Insert the supplied batteries and connect the insulated test leads if voltage or continuity functions are required. Open the clamp jaw and position it around a single conductor to measure current; ensure the jaw fully encloses the conductor and avoid clamping multiple conductors together. Read the measured value on the instrument display; use the TRMS mode for accurate results on non-sinusoidal signals. Follow standard safety procedures: de-energize equipment where practical, wear appropriate personal protective equipment and observe safe distances from live parts.

Usage recommendations

For reliable long-term performance, store the meter in the provided carrying case when not in use, replace batteries before low-voltage indications affect measurements, and periodically inspect the test leads and clamp jaw for wear or damage. Use TRMS mode for electronic loads and distorted waveforms and avoid exposing the instrument to prolonged moisture or extreme temperatures.
