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. You may find test mode
useful if you want to test the meter’s accuracy without
disrupting its billing registers. Test mode can be activated with
a push button on the meter front panel.
