Clamp Meter. To obtain maximum performance from the instrument, please read this
manual first, and keep it handy for future reference.
This instrument is a clamp meter that can perform true RMS measurement of current
simply by clamping it around a circuit. In addition to current, it provides voltage
measurement, frequency measurement, rush current measurement, resistance
measurement, diode measurement, capacitance measurement, temperature
measurement, voltage detection, and DC power measurement.
The CM4372 and CM4374 also provide Bluetooth communications functionality,
allowing measurement data to be monitored and logged from a smartphone or tablet.
