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