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.
- Operating instructions
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.
6. Self-calibration and Factory Reset
