A totalizer input from contact closures increments on the “open” portion of the
switch sequence close-open. To prevent switch contact “bounce” from triggering
false readings, select the Totalizer Debounce feature. A totalizer input from
voltage transitions increments during low-to-high voltage transitions with a
nominal threshold of +1.4 V. The maximum voltage input is +30 V dc, and the
minimum voltage input is -4.0 V dc. The maximum totalizer rate is 5,000
transitions per second without debounce and 500 transitions per second with
debounce.
The instrument reports totalizer status with scan data and can display it at the front
panel. You can initialize the totalizer count by cycling power to the instrument or
using Fluke DAQ software.
