DCM400
Low-cost AC clamp to 400 A with DMM functions and bar graph.
- 400 A AC
- CAT III 300 V
- Bar graph
The SANWA DCM400 is a slim, low-cost AC clamp meter with a 4000-count display and a 42-segment analog bar graph. Besides AC current to 400 A it measures voltage, resistance, frequency and continuity. Bhumika quotes this model for Canada.

Features
- AC current to 400 A
- 4000 counts with 42-segment analog bar graph
- Auto power off (30 min.)
- Low battery indication
- Frequency on both current and voltage inputs
