DCM301
AC True RMS clamp to 1000 A with EF detection and DC voltage.
- 1000 A AC
- CAT IV 600 V
- EF detection
The SANWA DCM301 is a True RMS clamp meter for AC current to 1000 A with DC and AC voltage, resistance and capacitance. It shares the DCM401's slim CT shape, EF tip and LED work light but measures AC current only. Bhumika quotes this model for Canada.

Features
- AC current to 1000 A, True RMS
- CAT IV 600 V / CAT III 1000 V
- EF function in the jaw tip detects approx. 90 V AC or more
- LED work light
- Shaped jaw for clamping in crowded cable runs
- Large, easy-to-press HOLD button
- Frequency, capacitance, resistance, continuity
