Optical fiber loss measurement
Step 1- Optical Reference Level
Turn on optical power meter and press the λ key to select the wavelength.
Turn on optical light source and select the wavelength. Wait for 1-2 minutes
until it stabilize. Select a piece of patch cords, which is used to connect with
the light source. The patch cords must be the same fiber type as the fiber
under test. Connect the light source with the Power Meter through the
source patch cords. Power Meter will get the power measurement value.
This value should be close to the value of the light source. If it has wide
disparity, please make sure the fiber connection is clean properly else
replace jumpers.
Press the dB key; 0dB will be displayed on the screen. The tested power
values will be set to the reference value.
Step 2-Optical Loss Measurement
Keep the source patch cords connection with the light source.
Connect the Power Meter and light source (emitting source) to the optical
fiber link respectively.

CARE OF
1. Always clean the mating connector tip and ferrule before mating, using
approved materials. Clean the instrument using alcohol or other non solvent
cleaning agents. Acetone or other active solvents may damage the case.
2. When not in use, keep connectors covered and away from dust. Dust and
other particles, however, can range from tenths to hundredths of microns in
diameter. Their comparative size means that they can cover a part of the end
of a fiber core, and as a result will reduce the performance of your system
3. During prolonged storage, remove batteries to eliminate the possibility of acid
leakage. Use only high quality sealed alkaline batteries.
4. Do not touch connector tips with your fingers, since body oils and dirt can
impair connector performance.
5. Do not use damaged or incompatible connectors.
6. Limit the input optical power doesn’t over measuring range.
7. The instrument is resistant to normal dust and moisture, however it is not
waterproof. If moisture does get into the instrument, dry it out carefully before
using it again.
8. This meter is a high-accuracy correct instrument, don't disassembly or
open it by yourself, otherwise the quality is not guaranteed.
9. During storage and transport, keep the instrument in its carry case to protect
against crushing, vibration, dust and moisture.
10. Where possible, keep instrument away from strong sunlight.
YOUR INSTRUMENT
Procedure for Stubborn Dirt
1. Moisten a new cotton swab with alcohol.
2. Clean the interface by rubbing the cotton swab over the surface using a
small circular movement.
3. Take a new, dry soft tissue and remove the alcohol, dissolved sediment and
dust, by rubbing gently over the surface using a small circular movement.
4. Blow away any remaining lint with compressed air.
