[F20] External input
This function is available when the model includes the external input function. The accumulated flow, peak
value and bottom value can be reset remotely.
: When using a model without external input function, this setting is not available and [---] will be displayed.
Accumulated flow external reset:
A function to reset the accumulated flow value when an external input
signal is applied.
In accumulated increment mode, the accumulated flow value will reset
to zero, and then increase from zero.
In accumulated decrement mode, the accumulated flow value will
reset to a set value, and then decrease from the set value.
: Each time the accumulated flow external reset is activated and when the
accumulated flow value is stored, a memory device (EEPROM) is accessed. The
memory device has a limit of 1 million cycles. When using the product, it should be
considered that the total number of external input resets and accumulated values
stored must not exceed 1 million.
Peak/Bottom value reset:
A function to clear the peak value or bottom value when an external input
signal is applied.
OFF:
The external input function will not operate.

Input signal:
The external input line must be connected to GND for a minimum of 30 msec.
When the input signal is ON, the screen will display [ooo] for 1 second.
After turning OFF the input signal, flow accumulation resumes (displays peak value and
bottom value) within 30 msec.
To input successive signals, the [ooo] display must clear before the next signal is input.
