(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.
¡ Display of measured value
At measurement state before a recording, the measured value is
displayed on the LCD at every 1 sec..
