Martindale CM57 AC TRMS Clamp Meter
The CM57 is a new pocket sized high performance AC Clamp meter measuring AC current, AC/DC voltage, resistance with continuity test plus capacitance, frequency and diode test. The compact rugged design enables accurate and reliable current measurement down to 10mA resolution without the need to break into the circuit.
True RMS measurement ensures reliable readings with distorted waveforms often caused by modern lighting and power supplies.
Features include a thumbwheel for single handed operation, auto ranging for ease of use, auto power off and low battery indicator plus a high contrast backlit display with hold function useful for working in low light and hard to reach areas. The Smart function automatically detects and switches between resistance and capacitance measurements.
The CM57 has a CATIII 600V safety rating and includes a non-contact voltage sensor built into the jaw for detecting the presence of AC voltages.
The CM57 TRMS Clamp Meter Comes Supplied With:
- Martindale TL16 Test Leads
- Soft Carry Case
- Alkaline Batteries
- All Martindale clamp meters come with a 2 year warranty.
- TRMS Meter
- Voltage, Resistance, Continuity, Capacitance, Frequency and Diode tests
- Single Handed Operation
