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. See Reset Meter to Factory Defaults on page
40 for details on resetting the meter to factory defaults. In
addition, for best results, we recommend using the free
MeterView XL software for all programming needs.
