Description
The functionality of a current clamp and a power and harmonics meter in a single handheld instrument.
The LH1050/1060 Power Clamp Meters are essential tools for power measurement and diagnostics on switching loads such as drives and high efficiency lighting. They combine the functionality of a current clamp and a power and harmonics meter in a single handheld instrument that has been designed for safety and ease of use.
True RMS for reliable measurement
Modern multimeters basically use 3 types of measuring methods: Mean value, peak value and true RMS measuring. When measuring pure DC or sinusoidal AC, clamp-on multimeters using the different methods show equivilent results. However in the case of ripple currents or even complex distorted currents typically found in power converters, PWM frequency inverters and mains supply circuits, the mean and peak value techniques ca result in substantial errors. In these common applications only the true RMS measurement technique employed in most LEM clamp-on instruments provide reliable readings. When measuring AC according to the peak value measuring method the peak value is measured and multiplied by a 0.707 correction factor while the mean value is multiplied by a 1.111 form factor. Neither give accurate results for non-sinusoidal waveforms.
Software
WinLog is an easy to use PC software and interface package for data logging applications with the LEM Power Clamps and HEME ISO Series insulation testers. The software can be used to continually log the electrical measurement displayed on the instrument or to download stored data from the Analyst and ISO2000 to a PC for further analysis.
Additional Features
- Check inrush characteristics with measurement of Peak voltage and current values
- Harmonic trouble shooting with measurement of Total Harmonic Distortion (THD), Distortion Factor (DF) and Crest Factor (CF)
- Monitor the effects of loads with dc Ripple measurement
