3.1 Deactivating the Auto-Off Function

Note: At power-up, the FOT automatically performs a self-test before the
measurement mode is displayed.
When the FOT is battery powered, it is automatically in auto-off mode (unit powers
off after 10 minutes of inactivity). To deactivate the auto-off function,
1. Power off the FOT.

3. Press o n / o f f , holding s e l e c t until the unit enters measurement mode.
The auto-off marker should not be displayed.
Note: To reactivate the auto-off function, power on the unit with the AC adapter-
charger plugged in, then unplug the adapter. The auto-off marker should be
displayed.

3.2 Calibration

For optimum performance, the FOT should be calibrated before each test session as
follows:
1. Ensure that the detector port is capped.
2. Power on the FOT.
λ
CAL
3. Press and hold s e l e c t until is displayed. The running lines on the
display indicate the calibration is in progress. After calibration, a dashed line is
displayed.
Note: If Err 1 is displayed, the calibration failed due to incident light on the detector.
Tighten detector cap, press any key to cancel the error message, then repeat
the calibration process.

3.3 Fiber Identification

To identify a fiber carrying a 2 kHz test signal,
1. Install the 2 kHz detection adapter on the detector port.
2. Place the fiber in the groove of the 2 kHz detection adapter and gently push
down the fiber. If the fiber carries a 2 kHz optical signal, the FOT beeps
2 seconds, and 2000 Hz is displayed.

3.4 Measuring Absolute Power

To measure absolute power,
1. If necessary, calibrate the FOT.
2. Install the appropriate connector adapter on the detector port, and connect the
fiber under test.
λ
3. Press s e l e c t to match the FOT and source wavelengths.
