7.1.4 Instruction of Status Bar Area on the Main Interface of OTDR
Fig.7-9 Schematic Diagram of Status Bar Information
Status bar of OTDR separately provides status display of 5 categories of function: display
of connection status, display of measurement model status, display of measuring progress
status bar, display of VFL status, display of power status.
Display of connection status: inspect the connection status of optical connector of OTDR.
Before beginning measurement, and after inspecting the communication light, OTDR will
automatically inspect the connector of instrument and the connection condition of the optical
fiber that waiting to be measured. The connection status includes two levels, good and bad. It
will prompt user after inspection, however, it won’t influence the measurement.
Display of measurement model status: measurement model includes average
measurement and real-time measurement. Under the models of average measurement and
real-time measurement, it will provide user functions of measurement starting and stopping,
and will prompt measurement status in the status bar of the measurement model.
Display of measuring progress status bar: when clicking the icon button “measurement”,
OTDR begins measurement, and the measuring progress status bar shows measurement
conducting; when measurement finished or clicking the icon button “stop”, the measuring
progress status bar shows measurement completed.
Display of VFL status: when starting using VFL function, the VFL status bar shows VFL ON;
when closing VFL function, VFL status bar shows VFL OFF.
Display of power status: OTDR instrument needs to display the using conditions of the
current battery on the status bar of the main interface. The status of battery includes charging
status and discharging status. When the battery is in discharging status, the current quantity of
electricity in the battery will be marked by five grades, separately are: full of electricity, greater
quantity of electricity remains, half electricity remains, insufficient electricity, and electricity run
out. When the battery is in charging status, the current quantity of electricity in the battery will be
marked by two grades: separately are: charging, full of electricity.
