A pocket clamp meter that can use flexible sensors
When connected to an optional flexible current sensor*, the CM3281 can be used to measure the current flowing in pairs of wires or in tangled or complexly routed wires around which it was not possible to apply a clamp-on sensor in the past. ＊AC FLEXIBLE CURRENT SENSOR CT6280 (4200 A AC, Φ130 mm)
Essential for electrical work: A thin card tester that fits in the pocket with all the capabilities of a clamp meter
The CM3281 delivers all the functionality of a clamp meter and card tester in the form factor of the latter. In addition to current measurement, this single instrument delivers voltage measurement, continuity check, and resistance measurement functionality.
