■[F20] External input
This function is available when the model includes the external input function. The accumulated value, 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.
When “Count up display”, the accumulated flow value will reset to
zero, and then increase from zero. When “Count down display”, 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 external 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.
