(1) Continuous recording mode ¡ Sampling period and RMS calculation The input signal obtained via the connected sensor is sampled (at 50Hz,approx 0.222mS; at 60Hz, approx. 0.185mS) just for 2-cycle (180 data). Then RMS value is calculated by the sampled 180 data. The instrument goes into stand-by mode till next recording interval comes. ¡ Recording The channels to which each sensor is being connected are switched in sequence at recording interval. Then RMS values are found by sampling the data for 2-cycle at each channel and recorded.
(2) Event 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 ...
