The OWON CM2100 is a compact smart AC/DC clamp meter for current, voltage, resistance, capacitance, frequency, duty cycle, diode, continuity, and NCV checks. It combines a 20000-count true RMS display, 100 A AC/DC current range, 600 V AC/DC voltage range, and VFC mode for measurements with high-frequency interference filtering.
Key features
- Measures AC/DC current up to 100 A and AC/DC voltage up to 600 V
- 20000-count true RMS automatic range clamp meter
- NCV non-contact AC voltage sensing
- VFC mode for voltage and current measurements with high-frequency interference filtering
- Frequency response from 40 Hz to 1000 Hz
- 17 mm jaw capacity in a compact clamp meter body
