Option: Totalizing Mode
Meters can be purchased with the Totalizing Mode option. This option adds an
additional mode screen that displays the total flow (normally in the units of the
main flow screen) that has passed through the device since the last time the
totalizer was cleared.
The Totalizing Mode screen is accessed by
pushing the TOTAL button on the MAIN display.
TOTAL/TIMER: Pushing the TOTAL/TIMER
button will cycle the large numbers on the
display between total mass and time elapsed.
Rollover – The customer can also specify at the
time of order what the totalizer is to do when
the maximum count is reached. The following
options may be specified:
No Rollover – When the counter reaches the
maximum count it stops counting until the
counter is cleared.
Rollover – When the counter reaches the maximum count it automatically rolls
over to zero and continues counting until the counter is cleared.
Rollover with Notification – When the counter reaches the maximum count
it automatically rolls over to zero, displays an overflow error, and continues
counting until the counter is cleared.
TOTAL MASS: The counter can have as many as seven digits. At the time of order,
the customer must specify the range. This directly affects the maximum count. For
instance, if a range of 1/100ths of a liter is specified on a meter which is totalizing in
liters, the maximum count would be 99999.99 liters. If the same unit were specified
with a 1 liter range, the maximum count would be 9999999 liters.
ELAPSED TIME: The small numbers below the mass total show the elapsed time
since the last reset in hours, minutes and seconds. The maximum measurable
elapsed time is 9999 hours 59 minutes 59 seconds. The hours count resets when
RESET is pushed, an RS-232 or RS-485 clear is executed or on loss of power. Press
ELAPSED TIME to show this as the primary display.
RESET – The counter can be reset to zero at any time by pushing the RESET
button. To clear the counter via RS-232 or RS-485, establish serial communication
with the meter or controller as described in the RS-232 or RS-485 section of the
manual. To reset the counter, enter the following commands:
