4. Button: press to Turn On / Turn Off the Meter.
5. Pen Clip: to fasten the tool while inside your pocket.
6. Battery Lid: open to change batteries.
7. Linchpin: locks the battery lid.
1. The Fiber Meter is powered by two 1.5v AAA batteries.
2. INITIAL CALIBRATION: Keep the Dust Cap closed and then turn on
the Fiber Meter by pressing the Button. The LED will show “CA”
which means the Initial Calibration is proceeding. After 3 seconds
the LED display will show “Lo” which means the Fiber Meter has
completed the Initial Calibration successfully and can now be
operated.
3. Lift the front Dust Cap up and insert one end of the fiber cable into the
universal connector or directly insert it into an output connector of a
fiber device or Power Source.
4. Switch the slide switch to 850 nm / 1300 nm position (for measuring
Multimode fiber) or to 1310 nm / 1490 nm / 1550 nm position (for
measuring Singlemode fiber). The LED figure shows the actual
receiving input power values.
5. “Lo” will be displayed when the actual power received is under
measuring range. When the input power is higher than the measuring
range, “Hi” is displayed on the LED indicator.
6. To measure the power loss of a fiber cable, you need a steady power
source. For example, the light source output power is -20 dBm after
a fiber cable transmission and the -10 dBm is read directly from the
LD power source. This means there is at least a 10 dB power loss after
the fiber transmission.
7. When the LED shows “Cb“(Check Battery), it means that the batteries
are almost drained and in a low voltage state. You need to replace the
