ANSI Electric Meter v3.1 User’s Guide 11
Test Mode
Test mode is an optional feature that is only supported by some NES version 3.1 ANSI
meters. While in test mode, the meter will suspend standard energy accumulations,
standard demand calculations, power quality analysis, tariff register calculations,
automated control of the disconnect switch, and automated control of the control relay.
In addition, all standard operation demand calculations that were interrupted by test
mode activation will be considered completed and the values will be calculated as if the
full time of the demand interval has elapsed (the non-elapsed time is considered to have
had an energy accumulation of zero). You may find test mode useful if you want to test
the meter’s accuracy without disrupting its billing registers. The meter display includes
an icon that will be enabled when the meter enters test mode.
