channel 1 starts counting immediately and the counting continues from the last recorded
counter value.
The function of clearing the counter value to 0 is enabled; the count value of
2
ASRTU-EC16AP1TA's counter channel 1 is cleared to 0 and meanwhile counter channel 1
stops counting immediately.
Note:
Please connect a resistor of 2.2K ohm between the input points and S/S common terminal when the input
frequency exceeds 100 kHz.
