*1 You can select if the data of file type 1,2 and 3 is written to SD memory card with the setting mode.
*2 With using clock correction function, it synchronizes with the measured voltage (50Hz/60Hz) automatic
recognition and corrects the clock. In case of a power failure, it measures time by using the internal clock
and backup battery. In this case the accuracy is applied to the accuracy without clock correction.
You can select if it corrects a clock or not with the setting mode.
*3 The reference frequency for using the time synchronizes is the frequency of measured voltage input to
P1-P0 terminals. It doesn’t correct the time when P1-P0 terminals are not connected. In case of that it
detects an abnormal for the reference frequency; it will shift to the internal clock. When it detects a normal
frequency after that, it synchronizes with the frequency of measured voltage and corrects the time.
*4 When battery power is reduced, ‘BATT’ is blinking. Replace battery according to the procedures.
Battery life will be short if using this under high-temperature.
