Remarks:
1) Wavelength range: the calibrated operating wavelength range from
800nm to 1700nm, in which the optical power meter can work under
specified index.
2) Measurement range: the range in which the maximum power can be
measured according to the specified index.
3) Uncertainty: the error between the measurement results of a given
optical power and a standard optical power.
4) The measurable optical fiber length is for reference.
5. Operating Instructions
5.1 Measurement of Absolute and Relative Power
5.1.1 Absolute Power Measurement
Set the test wavelength and access the test optical signal. Then the screen
will display the measured linear value (in mw, nw, uw) and nonlinear value
(in dBm) of the absolute optical power.
5.1.2 Relative Power (Loss) Measurement
Relative power measurement is mainly used to measure insertion loss or
fiber link loss.
a) Use a standard test jumper to connect the output port of a light source
to the optical power interface of the optical multimeter.
b) Set the test wavelength and access the test optical signal. Then the
screen will display the measured linear value (in mw, nw, uw) and
nonlinear value (in dBm) of the absolute optical power.
c) Press and the measured absolute optical power will be saved
the reference power value and displayed as xx.xx dBm on the second
as
line of the screen.
d) Connect the optical fiber under test to the light source and the optical
multimeter. The difference between the current optical power value
and the reference power value will be calculated and displayed as
y.yy dB on the third line of the screen, which is approximately the
insertion loss of the optical fiber under test.

Note:
①
P (Reference power value) (dBm) = p (Light source output power)
(dBm) – L (Insertion loss of the standard test jumper) (dB)
②
L (Insertion loss of the optical fiber under test) (dB) = [P (reference
power value) (dBm) – p (current power value) (dBm)] – L (Insertion
loss of the standard test jumper) (dB)
The optical multimeter can automatically identify the frequency of 0Hz,
270Hz, 1000Hz and 2000Hz emitted by the light source.
5.2 Visual Fault Locator Function Test
1) Open the left dust cap and insert the optical fiber under test into the
visual fault locator interface.
2) Press in the power on state, and select the continuous red light
or pulse mode to test.
3) After the test, pull out the optical fiber, cover the dust cap, and then turn
off the optical multimeter.
5.3 LAN Cable Sequence Test
1) Remove the slave device from the buckle of the master device.
2) Connect one end of the LAN cable under test to the RJ45 interface of
the master device and the other end to that of the slave device.
3) Power on the optical multimeter, long press for 2s to turn the LAN
cable sequence test mode on and “RJ45” will be displayed on the LCD.
If the corresponding line sequence indicators (1~G) on the master and
slave devices are lit in turn, the line sequence of the measured LAN
cable is correct. Otherwise, the line sequence is incorrect. The status
(open circuit, short circuit, cross circuit, etc.) of the LAN cable can be
judged by the line sequence indicators.
Please keep the end face of the sensor clean, free from grease and
contamination. Do not use unclean or non-standard adapter connectors.
Do not insert the end face with poor polishing.
Please stick to a kind of adapter as far as possible.
Once the equipment is not in use, please cover the dust caps immediately.
Please insert and remove the optical adapter connector carefully to
avoid scratches on the port.
Please wipe the sensor surface gently and regularly with a special
cleaning swab in the circumferential direction.
