AC/DC Clamp-On Multimeter

Measures Current, Voltage Resistance, Diode Test

Large 55 mm (2.2") Jaws Opening

Auto-Ranging and Auto-Zeroing

Display Hold Button

Analog Output for Current Measurement for Use with Recorders, Data Loggers and Oscilloscopes

CE Approval

The HHM46 clamp-on multimeters provide true RMS AC/DC measurements, even when harmonics are present. The HHM46 Series measures current from 200 to 2000A, voltage and resistance. Continuity and diode testing can also be performed. The unit also conforms to IEC 1010 safety standards and EMC requirements.

With optional leads, an analog output is provided for use with recorders, dataloggers and oscilloscopes. The output, either instantaneous or RMS current measurement, is switch programmable by a slider switch located in the battery compartment.
