1 Complete safety and a reliability that you can count on... Designed with an emphasis on safety 2 types of DMMs for measuring differences in distorted waveforms ■Measures RMS values of commercial mains power frequencies PWM control voltage waveform ■Accurately measures harmonic wave Accurate measurements components are guaranteed for components in the range from 50 to 500 Hz . Makes RMS measurements that exclude harmonic components. ●Crest factor: 3.0 max.
2 Practical functions I want to see fluctuations with respect to the current value... I want to zero adjust the resistance range... Relative function This setting can be used with the V, A and Ω functions. Any value can be set as the reference value and values can be displayed relative to the reference value. H.AUTO / REL Press for at least 1 second I want to keep track of values measured... H.AUTO / REL Memory function (REC.
