(3) Max. value recording mode
¡ Current detection and RMS calculation
Sampling is performed consistently 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. At the same time, RMS is
calculated at 100ms based on the sampling data at every 3.3ms.
¡ Recording
When the preset current value is exceeded (Point A), the instrument
starts recording and ends either when the value drops to below 50%
of the set value, or after an elapse of 10min. During the recording
period, the instrument records the max value reached every 10secs.
In case the event that exceeds the preset current 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 the selected channel is displayed on the LCD at every 1
sec.. The max. value is displayed on the LCD at every 10 sec. during
a recording.
