Differential current measurement method with BENNINGCM9
■automatic selection the correct measuring function for TRUE
RMS voltage/current (AC/DC), resistance, continuity and diode test
■safe and easy operation measuring errors due incorrect
measuring range selection are excluded
■short response time due scanning values per second
■voltage measurement with low input impedance (LoZ) to
suppress capacitively/inductively induced voltages
