Utilisation of Hall effect technology ensures a broad flat frequency response resulting in optimum accuracy even when harmonics are present. 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. True RMS measurement By using True RMS measurement techniques the 40-series instruments avoid errors (up to 50%) which can occur when nonsinusoidal waveforms created by today’s complex loads are measured using traditional average-reading techniques. True RMS measurements are available for AC, DC (A, V) and AC+DC (A).
