¡ Current detection and RMS calculation
Sampling is performed consistently only at Channel 1 at 1.6ms
intervals. Current is detected by comparing the 1/√2 times of the
peak value of sine wave and the preset current value.
¡ Recording
When the preset current detection value is exceeded (Point A),the
instrument records instantaneous values with corresponding time
information for 200ms(10 to 12 waveforms) including 50ms prior to
and subsequent to the cross over point. In case the event that
exceeds the current detection value occurs continuously, current will
not be detected until it drops to 50% or less of preset current value
as the last detected leakage current is remaining.
¡ Display of measured value
At measurement state before a recording, the max. measured
value (RMS) at Channel 1 is displayed on the LCD at every 1 sec..
(* Waveform cannot be displayed on the LCD of the instrument.
Transfer the data to PC by using PC software of accessory, and
check the graphic display.)
