14.7 Status LED states
The status LED on the transmitter indicates whether or not alerts are active. If alerts are active, view the alert
list to identify the alerts, then take appropriate action to correct the alert condition.
Your meter has one or two status LEDs:
• A status LED on the display (only if your meter has a display)
• A status LED on the board, beneath the meter housing cover
CAUTION
If your meter is in a hazardous area, do not remove the meter housing cover. Use a different method to
determine meter status.
The status LEDs use colors and flashing to indicate device status.
