9.2.23 SERCNT (Serial Count)
Serial count is used to program the number of readings the meter must take (programmable from “00001” to
“59,999”) between transmissions of data via the optional RS-232 or RS-485 serial communications board.
Once you are done with the changes, press the ‘MENU’ button to display the normal operating display. The meter
advances to run mode showing the currently measured values. Pressing the ‘RESET’ button two times allows you
to return to the run mode.
