7-2 Measuring and recording method
1) Continuous recording mode
Switch the channel to which the sensor is connected every at
recording intervals. After recording, stand-by until next
recording interval comes. Import 180data of input signal by
sampling during 2cycles from the connected sensor, and
calculate true RMS. Measurement result will be displayed at
every 1sec.
2) Event recording mode
Do sampling consistently at 1.6ms intervals, and compare and
judge the peak value of sine wave that is converted into RMS
and current set value. At the same time, calculate RMS every
at 100ms from the sampling value at every 3.3ms. When the
event which exceeding detected current value happens, total
8data(for about 0.8sec.): 3RMS prior to when exceeding the
value and 4data subsequent to it is recorded. In addition, the
peak value and time when detecting the exceeding current will
be recorded.
After recording, current will not be detected until current drops
to 50% or less of set current value as the last detected leakage
current is remaining. On the selected channel, measured max.
values during measurements at every 100ms will be displayed
at every 1sec.
