18.9 Counters
The pump cumulatively records hours of motor operation and volume of fluid
pumped. The figures can be displayed or reset to zero.
In the third screen of the Setup menu select Counters using the UP and
DOWN keys. Press ENTER to confirm your choice.
The pump briefly displays the total volume pumped and hours the motor has
operated since the last time the counters were reset to zero, followed by an
opportunity to reset the counters to zero. An example is shown here.
A two-screen menu is displayed offering Both, None, Run time or
Cumulative qty. Use the UP and DOWN keys to scroll a highlight up and
down the list (if DOWN is pressed while Run Time is highlighted, or UP is
pressed while Both is highlighted, the menu will move to its second screen
with Cumulative qty highlighted). Press ENTER to confirm your decision. The
total volume and hours screen is displayed with its totals reset to zero, or
unchanged. The pump displays the third screen of the Setup menu.
Note: Cumulative volume and Run time are displayed on the Combined display. See
18.3 Display. Cumulative volume is set to zero when factory default is selected. Run
time is not set to zero when factory default is selected.
