GENERAL INFORMATION
The Fiber Optic Test Set is a measurement system containing an optical source and a digital
radiometer in one self-contained unit. The optical source is a solid state Light Emitting
Diode (LED) that operates in the visible red region of the electromagnetic spectrum. The
radiometer uses a silicon photodetector sensitive to visible and near-infrared light. The two
components can be operated together or independently, permitting great measurement
fl exibility.
The LED and the photodetector are contained inside industry-standard “ST ® ” style fi ber
optic connectors which are accessed through the front panel. The test set is battery-
operated, allowing portable use in the fi eld and lab.

Controls
On/Off Switch
The “ON/OFF SWITCH” is a
“push on - push off” switch that
applies power to the test set.
Pressing the switch will activate
the LCD Display, and energize the
LED source for approximately one
second. Pushing the switch again
will remove battery power from
the internal test set circuitry.
Display Selector Switch
The “DISPLAY SELECTOR
SWITCH” is used to select
the full scale sensitivity of the
test set’s radiometer which is
indicated on the LCD Display.
Four power ranges are provided:
20 microwatts (µW), 200 µW, 2
milliwatts (mW), and 20 mW.
