Perform the procedure in Figure 2-16 to display the instrument Totalizer status.
The instrument updates the Totalizer display once per second. (See Figure 2-15
for examples.) To clear the Totalizer count, cycle the instrument power. You can
also configure NetDAQ Logger to clear the Totalizer count when it starts logging.
• Maximum Totalizer Count The Totalizer counts switch closures or voltage
transitions with a maximum count of 4,294,967,295.
• Totalizer Status Display The instrument displays the Totalizer status in two
five-digit segments; high (HI) and low (LO). Using the maximum count of
4,294,967,295 as an example, the HI five-digit segment would display 42949
and the LO five-digit segment 67295.
