Select Display Function
The ER-500 monitor has three display selections— Flow, Grand Total and Test.
Flow
Use the Flow setting for normal operation of the monitor. In this mode, the display shows both the instantaneous flow rate
and current total simultaneously, see Figure 6.

Flow Grand Total
The Flow-GT setting forces the meter to alternate between the instantaneous flow and the grand total with roll-over counts,
see Figure 7.
The grand total is the accumulation of all the fluid that has gone through the meter since the last time the grand total was
cleared. This totalizer is in addition to the current total totalizer on the display and is always enabled.
In addition, the grand total screen displays the number of times the grand total has reached its maximum count (9,999,999)
and rolled over to zero.

Test
The Test setting places the monitor into a special diagnostic mode that shows the current input frequency and the
accumulated input counts. Figure 8 shows the layout for test mode values. The diagnostic mode makes it possible for you to
see precisely the frequency input the monitor is seeing and is very useful in troubleshooting and electrical noise detection.
At the Display prompt, press ENTER to view the current display setting. If the current display setting is correct, press ENTER to
advance to the next parameter. To change the display setting, press UP or RIGHT to scroll through the display options. Press
