or 1 to 4 hours (in increments of 1 hour).
Average value resetting:
The above-mentioned output of average
value is started from the initial state by
opening the average value resetting input
terminals after short circuiting for 1.5 sec
or longer.
Output is reset by input voltage and
restarted by opening the terminal circuit.
