AC LEAKAGE CLAMP METER
CM4003
(Output and external power supply function)
Identify potential problems and avoid large problems

Key Features • Wireless support. Transfers measurements to your smartphone or tablet. (Optional Wireless Adapter Z3210 is necessary) • Detect minuscule leakage currents with a newly designed sensor. (Core jaw diameter up to φ 40 mm) • Broad measurement range extending from leakage currents to load currents • Solve GFCI and RCD problems quickly • Speed up pass/fail judgments with the built-in comparator function • Output function (waveform/RMS): use with a recorder to record waveforms and fluctuations • External power supply: use an optional AC adapter for continuous, long-term measurement CAT III 300 V |
Model No. : CM4003![]() When Z3210 is installed |
Connect the Z3210 to add wireless communications
Easy visualization of intermittent trip events
Connect the Wireless Adapter Z3210 (sold separately) to add wireless communications. |
Regular inspections of GFCIs and RCDs [Photo drawing function]
Record measurement locations and measured values together. |
Identifying intermittent trip events [Event recording function] The meter records event information (times and current values) in its internal memory. Collect data using a tablet and check for trips! |
Detect minuscule leakage currents with a newly designed sensor IEC/EN 61557-13 compliant
The core and shielding are constructed from high-permeability magnetic materials. |
High-reliability leakage current measurement
1. Uniform measurement sensitivity inside jaws: When affixed around a wire, sensitivity is uniform regardless of the position of the conductor inside the jaws. |
Measurable conductor diameter up to φ40 mm
The jaws have a maximum diameter of φ40 mm and can be used to pinch thick cables or multiple cables at once. |
Long-time continuous measurement with output function and external power supply function
Waveform/RMS output function. Waveforms and fluctuations can be recorded in combination with a recorder. |
