CM-2056 Overview
CM-2056 clamp meter. available to DC voltage, AC voltage, DC current, AC current, resistance, capacitance, frequency, non-contact voltage, temperature, diode and continuity tests; Designed with unit symbol and backlight display, data hold, clamp lighting, auto ranging switch, auto power off and alarm functions.
4000 counts display
The CM-2056 is a 4000-count True RMS AC/DC clamp meter with a 52mm jaw. It measures AC and DC current to 1000A on 40A/400A/1000A ranges at ±(1.5%+5), DC voltage to 1000V and AC voltage to 750V, and adds capacitance, frequency and temperature for full troubleshooting on heavy installations.
Key features
- DC and AC current 40A/400A/1000A, ±(1.5%+5)
- DC voltage 400mV to 1000V, ±(0.5%+5); AC voltage 4V to 750V, ±(0.8%+5)
- Resistance 400Ω to 40MΩ, ±(0.8%+1); capacitance 4nF to 40mF, ±(2.5%+5)
- Frequency 10Hz to 10MHz, duty cycle; temperature -40℃ to 1000℃, ±(1.0%+5)
- NCV, REL, Max/Min data hold, diode test, clamp light and backlight
- Safety rating CAT.III 600V
Applications
Industrial plants, large commercial switchboards, generator sets, solar and battery DC systems, and motor control centers where one meter has to handle 1000A cables and also check capacitors and frequency.
Choosing within the series
The CM-2056 is the upper model of the 1000A AC/DC pair. Compared with the CM-2046 it has a 4000-count display instead of 2000, current accuracy of ±(1.5%+5) instead of ±(2.0%+5), better AC voltage accuracy at ±(0.8%+5), and adds capacitance, frequency and duty cycle. Jaw size, 1000A current and 1000V DC are the same on both.
