CM-2000D 400A True RMS AC Clamp Meter, NCV

The CM-2000D is a 4000-count True RMS AC clamp meter for everyday electrical checks. It measures AC current to 400A on 4A/40A/400A ranges with ±(2.0%+5) accuracy, plus AC and DC voltage to 600V and resistance to 40MΩ. The 28mm jaw, clamp light and backlight make it practical inside crowded distribution boards.

Key features

• AC current 4A/40A/400A, ±(2.0%+5)
• DC voltage 400mV to 600V, ±(0.5%+5); AC voltage 4V to 600V, ±(1.0%+5)
• Resistance 400Ω to 40MΩ, ±(0.8%+3)
• NCV detection, diode test, continuity alarm below about 50Ω, relative (REL) measurement
• Data hold, clamp light and backlight, auto or manual range, 10MΩ input impedance, auto power off after about 15 minutes
• Safety rating CAT.III 600V

Applications

Household and light commercial wiring, socket and lighting circuits, and routine current checks on loads up to 400A. It suits distributors who need a low-cost True RMS clamp with a 4000-count display.

Choosing within the series

The CM-2000D is the core-function model of the 4000-count group in the CM2000 series. The CM-2000E keeps the same ranges and adds capacitance (4nF to 4mF), frequency, duty cycle and temperature. The CM-2007 adds the same extras and raises AC current to 800A with capacitance to 40mF. CM-2000B and CM-2000C have 2000-count displays and 600A AC range. Pick the CM-2000D when voltage, current, resistance and NCV are all the job needs.
