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
MeterView Pro
software for all programming activities. A 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.

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 36. In addition, for
best results, we recommend using the free MeterView Pro software for all programming needs.
