The title bar at the top of the screen displays status indicators during certain conditions. These indicator symbols flash to inform you that the meter is
- conducting a repetitive measurement,
- paused (the measurement is not updated),
- displaying a file,
- in need of a charge,
- receiving a charge, or
- in need of service.

Active Channel Plan Name

The active channel plan name is located on the far right in the title bar directly under the battery level indicator.

Battery Level

The battery symbol to the left of the battery level indicator begins to flash when the battery charge condition is extremely low. On the left side of the title bar (just to the left of the mode title), look for the following symbols to appear when you are using the meter:

Heartbeat

A triangular "heartbeat" icon indicates the beginning of each measurement cycle on screens where measurements are repetitive.

Pause

A pause icon (two thick vertical lines) appears when you enable the pause function and the measurement is not updated.

File

A file icon appears whenever a file is viewed.

Hardware Error

An exclamation mark (!) appears when the meter has experienced a hardware error and the measurement data is no longer reliable. Contact you nearest JDSU Technical Assistance Center for further instructions if this occurs.
