Greenlee CM-750 Digital Clamp-00 Multimeter
The Greenlee CM-750 Digital Clamp-on Meter is a hand-held testing devices with the following measurement capabilities: AC and DC voltage, AC and DC current, and resistance. It also verifies continuity. The display holds a measurement for later viewing or holds the maximum reading. The CM-750 is a true RMS reading meter.
The jaw can accommodate a conductor up to 35 mm (1.38") in diameter. In addition, the meters feature the following:
- Autoranging
- Zeroing key for DC amps
- Selectable auto power off
- Circuit protection to 600 volts
- 100 mA resolution up to 400 amp
AC measurements are usually displayed as RMS (root mean square) values. The RMS value is equal to the value of a DC waveform, which would deliver the same power if it replaced the time-varying waveform. Two AC measurement methods are average-responding RMS calibrated and true RMS-reading.
The average-responding RMS calibrated method takes the average value of the input signal after full wave rectification, multiplies it by 1.11, and displays the result. This method is accurate if the input signal is a pure sine wave.
The true RMS-reading method uses internal circuitry to read the true RMS value. This method is accurate, within the specified crest factor limitations, whether the input signal is a pure sine wave, square wave, triangle wave, half wave, or signal with harmonics. The ability to read true RMS provides much more measurement versatility. The Greenlee CM-750 is a true RMS meter.
