Environment
PM8000 LED indicators
Resolution
There are multiple LEDs on PM8000 meters as shown below:
See below for more information about each LED:
Alarm LED
Status/operation LED:
(Infrared) Energy pulsing LED:
Energy pulsing is used to help verify the energy measurement accuracy of the meter for revenue purposes.
The visible and infrared LEDs are configured by default to pulse based on energy measured by the meter.
The pulse weight (pulses per kWh) and the energy source can be configured, except in the case of the PM82401 which requires a specific pulse weight for MID compliance.
Revenue lock LED:
The revenue lock LED indicates the lock status of the meter
Remote display connection LED:
There are two LEDs in the remote display connector that indicate the state of communications between the meter and remote display.
Expansion I/O LED:
NOTE: for more information on the PM8000, refer to the PM8000 FAQ.
