Troubleshooting Tips
This meter is a highly sophisticated instrument with an extensive list of features and capabilities. If the programming
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 programming buttons and it is not working as intended, try re-programming
the meter using MeterView Pro software.
Symptom
Check/Action
No display at all
Check power at power connector
Not able to change setup or programming,
Locd
is displayed
Meter is password-protected; enter correct six-digit password to
unlock or Master Password of 508655
Meter does not respond to input change
If a
Low-Flow 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-flow
cutoff value.
To prevent the display from showing a negative value, set the
low-flow cutoff to a value greater than zero.
