Operation
Zeroing the Total.
To reset the volume total with an explosion-proof switch, press and hold the switch for at
least 3 seconds, then release it.
Important: When resetting the volume total with the explosion-proof reset switch, do not release the
switch prematurely. Releasing the switch too quickly (before 3 seconds have passed) will
activate the daily log view function and WILL NOT reset the volume to zero.
Viewing Daily Logs
. To view daily logs with the explosion-proof switch, press and release the switch. (Do not
depress the switch for more than 1 second.) The words “Daily Volume Archive” will scroll across the bottom
of the LCD and the day index (Figure A.3) will display “01.” The daily flow total recorded at the last contract
hour will appear at the top of the LCD.
The index number represents the number of days previous to the current date. For example, totals from two
days previous are read by pressing the switch until “02” appears in the Day index field of the display.
Subsequent press-and-release actions increment the daily index, allowing the user to select a specific daily
total.
