● Detection and RMS value calculation
Sampling the inputs at every 0.55ms only at CH1 and comparing the
Peak value (sampled crest value converted to sine RMS value) and
Detection level. For current, when the Peak value exceeds the level
and for voltage when the Peak value is below the level; detection is
triggered. RMS value is calculated at every 100ms.
● Recording
When the preset current value is exceeded, instantaneous values
with corresponding time information are recorded for 200ms ( 10 or
12 waveforms) including 50ms prior to and subsequent to the cross
over point. In case that events exceeding the Detection level occur
continuously, next detection doesn't start until it drops to 50% or less
of the detected value. (for voltage, 5% or more than the detected
value)
● Display of measured value
Average of RMS value is displayed on the LCD at every 1 sec.
