Additional Features LH635/LH1035
•
•
True RMS measurement of distorted or nonsinusoidal AC waveforms
Max-Hold mode displays highest
measured value
High Accuracy
True RMS measurement
Advanced jaw design means that 30-series accuracy is little
affected by external magnetic fields or off-centre conductor
positioning. Utilisation of Hall effect technology ensures a broad
flat frequency response resulting in optimum accuracy even when
harmonics are present.
By using True RMS measurement techniques the LH635 and
LH1035 gives maximum accuracy for non-sinusoidal waveform
measurements often found with today’s complex loads.
IEC 1010 and EMC Conformance
IEC 1010 safety features including a tactile barrier and special
jaw design provide the user with confidence when making
measurements in hazardous voltage areas.
Conformance to EMC standards ensures high reliability through
reduced susceptibility to electromagnetic interference.
