The Totalizer Mode; Totalizer Example - Omega DPF700 User Manual

The totalizer mode registers a precise total count. Use the totalizer mode for cumulative totals
and stopwatch (timer) applications. Meter up-counts (positive scale factor) or down-counts
(negative scale factor).
To use the meter as a totalizer permanently, set the function to
nonvolatile memory (to retain the change if power loss occurs). The meter defaults to the up-
count mode. To count down, use a negative scale factor and a positive offset (display = input x
scale + offset).
In case of power failure, if the S1-10 switch is set to open the meter blanks
the display and stores the latest reading in nonvolatile memory.

5.1 TOTALIZER EXAMPLE

You are totalizing pulses from a flowmeter which generates 25 pulses per gallon. To show the
total value in gallons:
* Set the meter to the totalizer mode.
* Use divide (IN /SC) by 25 as a scale factor
* Store set up information in nonvolatile memory.
Refer to Table 6-1 for summary list of menu configurations.
Note
Follow these steps for the above example:
1. Press the MENU button. The meter shows "
2. Press the £ SET button until the meter flashes "
3. Press the MENU button. The meter shows "
4. Press the £ SET button. The meter shows "
divide by (/) symbol flashing. Press the £ SET button until the meter shows "
Use multiply (.) when scale factor is less than 1, use divide by (/) when scale factor (or
Note
pulses/units) are greater than 1.
