Troubleshooting Tips
This meter is a highly sophisticated instrument with an extensive list of features and capabilities. If the front panel
buttons are used to program the meter, it may be a difficult task to keep everything straight. That is why we strongly
recommend the use of the free
software for all programming activities. A USB cable is provided with
the meter for programming with MeterView Pro software.
If you have programmed the meter with the front panel buttons and it is not working as intended, try
re-programming the meter using MeterView Pro software.

Meter does not respond to input change
If a
Low-Height Cutoff
Value has been programmed, the meter will
display zero below that point, regardless of the input
– which can
appear like the meter is not responding to an input change. Check
to make sure the problem is not being caused by an undesired
low-height cutoff value.
To prevent the display from showing a negative value, set the low-
flow cutoff to a value greater than zero.

Call Technical Support for assistance.
Note: Certain sequences of events can cause unexpected results. To solve these issues, it is best to start fresh from
factory defaults and use the manual as a step by step programming guide, rather than a random approach to
programming. To reset the meter to factory defaults, see Reset Meter to Factory Defaults on page 46. In addition, for
best results, we recommend using the free MeterView Pro software for all programming needs.
