Graphical Display Indicators
The PowerSmart Socket PQM graphical display is used both
for displaying billing and instrumentation data, and for
indication of the present tariff rate, time and important
diagnostic information. See
Status Indicators in Chapter 3 for
information on graphical status indicators.
Energy Pulse LED Indicators
The PowerSmart Socket PQM is provided with two red LED
indicators labeled as “WATT” and “VAR” that flash when a
load is applied to the meter.
The LED pulse rate in NORMAL mode is indicated by the Kh
watthour meter constant on the meter nameplate. The
standard Kh values and LED pulse rates are listed in the
following table. All indicated rates are in secondary units.

TEST Mode
The PowerSmart Socket PQM can run in NORMAL or in TEST
mode. The present operating mode is indicated on the display
status bar at the bottom of the screen.
TEST mode is intended for testing the device energy
measurement accuracy without affecting the billing energy
and demand data. All instrumentation data is still available in
TEST mode.
The front pulse LED indicators flash at a programmable rate
in TEST mode, and the billing data display shows separate
test kWh and kvarh energy readings with an extended 0.001
