BM803A+ True RMS AC/DC Clamp Meter – 1000A, 52mm Jaw, NCV, Frequency
The BM803A+ is a large-jaw true RMS clamp meter that measures both AC and DC current up to 1000A. The 52 mm jaw closes around thick battery and inverter cables, so it suits solar, UPS and industrial panel work where DC current matters.
With the test leads it also covers DC voltage to 1000V, AC voltage to 700V, resistance, capacitance, frequency up to 40MHz, duty cycle and temperature, on an auto-ranging 3999-count backlit display with NCV live-wire detection.
