CM-2046 Overview
CM-2046 clamp meter, DC voltage, AC voltage, DC current, AC current, resistance, non-contact voltage (NCV), temperature, true RMS, diode and continuity tests; Designed with unit symbol and backlight display, data hold, clamp lighting, auto ranging switch, auto power off and alarm functions.
2000 counts display
The CM-2046 is a 2000-count True RMS AC/DC clamp meter built for large conductors. Its 52mm jaw takes heavy cables and busbars, and it measures AC and DC current to 1000A on 20A/200A/1000A ranges at ±(2.0%+5). DC voltage goes to 1000V and AC voltage to 750V.
Key features
- DC and AC current 20A/200A/1000A, ±(2.0%+5)
- DC voltage 200mV to 1000V, ±(0.5%+5); AC voltage 2V to 750V, ±(1.0%+5)
- Resistance 200Ω to 20MΩ, ±(0.8%+1)
- Temperature -40℃ to 1000℃ (-40℉ to 1832℉), ±(1.0%+5)
- NCV, REL, Max/Min data hold, diode test, continuity alarm below about 50Ω, clamp light and backlight
- Safety rating CAT.III 600V
Applications
Main feeders, distribution switchboards, generator and welding cables, battery banks and DC bus work, where conductors are too thick for a 28mm or 35mm jaw.
Choosing within the series
The CM-2046 and CM-2056 share the 52mm jaw, 1000A AC/DC current and 1000V DC voltage. The CM-2056 has a 4000-count display, tighter current accuracy of ±(1.5%+5) on 40A/400A/1000A ranges, and adds capacitance (4nF to 40mF), frequency and duty cycle. The CM-2046 has a 2000-count display and covers voltage, current, resistance and temperature. Choose the CM-2046 when you only need high-current and voltage readings.
