TEST mode LED energy pulsing

Above the display screen are two pairs of energy pulsing LEDs and infrared outputs. The LEDs and IR outputs are factory-configured to pulse while the meter is in TEST mode.

A	WATT infrared output
B	WATT LED
C	The Kt label indicates the default pulsing rate
D	VAR infrared output
E	VAR LED

The energy pulsing LEDs provide an interface for accuracy checking instruments. The Kt label indicates the factory-configured pulsing rate. (You can change the energy pulsing frequency with Power Monitoring Expert or ION Setup.) See Configuring energy pulsing for more information on configuring the LED settings.
