MD 9272 is a unique earth leakage clamp meter. It not just has the ability to accurately read the TRMS AC leakage current of a system, it can also detect losses in the system and suggest possible reasons for the loss. The voltage (AC/DC), frequency, power, harmonic, power factor (PF), total harmonic distortion (THD) and crest factor measurements make this instrument suitable for any electrician and engineer.

Properties
Measuring functions
- TRMS AC voltage measurement;
- TRMS AC current measurement;
- Frequency measurement;
- Power parameters measurement.
Key features
- TRMS: accurate measurements on sinusoidal and non-sinusoidal signals.
- Jaw size: 28 mm.
- Shielded Jaw: shielded jaw allows the clamp meter to be used in the noisiest environments.
- Accurate: readings of AC current with an accuracy of 0.8 % and a base resolution of 0.01 mA and voltage with an accuracy of 0.5 % and a base resolution of 0.1 V.
- Power: measures various power parameters (active, reactive, apparent power, THD, PF, phase displacement).
- Intelligent loss analysis: complex algorithms detect loss and allow determining possible reasons for current loss.
- Harmonics: measures current or voltage harmonic components and a percentage value of a harmonic up to the 19th.
- THD and PF: dual display allows readings to be displayed along with Total Harmonic Distortion (THD) or Power Factor (PF).
- Peak value: the peak value of the waveform or crest factor can be displayed.
- MAX/MIN/HOLD mode: displays maximum, minimum or average measured value.
