The FOT measures optical power (FOT-10A, FOT-20A, and FOT-30A) and loss
(FOT-20A and FOT-30A) at 5 precalibrated wavelengths in multimode and
singlemode fibers. A 2 kHz signal detection feature is also included for fiber
identification. The FOT-30A can be configured with a single- or dual-wavelength LED
or laser source.
The FOT is powered by the 9 V alkaline battery or the AC adapter/charger.

PERATION PERATION 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, Power off the FOT. - Page 4 The reference value just stored applies only to measurements taken at the current wavelength. If you are using a dual-wavelength source, select the second wavelength and repeat steps 4 to 7. FOT-10A, FOT-20A, & FOT-30A...
