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 position (for measuring Multimode fiber) or to
1310 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 batteries right away.
8.
Do not touch the fiber’s interface in order to avoid dirt contaminating the
connector.
9.
Keep the fiber connector capped at all times when the device is not in use.
10.
If you use proper tools to clean the fiber before testing, you will obtain accurate
