Solution to inaccurate testing of optical power meter

Used to measure absolute optical power or relative loss of optical power through a section of optical fiber. In fiber optic systems, measuring optical power is the most fundamental, much like a multimeter in electronics. In fiber optic measurement, optical power meter is a commonly used heavy load meter. By measuring the absolute power of the transmitter or optical network, an optical power meter can evaluate the performance of optical devices. By combining an optical power meter with a stable light source, it is possible to measure connection losses, verify continuity, and help evaluate the transmission quality of fiber optic links.
The practical performance of optical power meters makes them important in fiber optic testing. What should we do if your optical power meter fails to accurately test a fiber optic line, which will greatly affect your judgment? How to maintain it during regular use?
The correct posture for normal use of optical power meter:
1. When using an optical power meter, first insert the handle directly and do not shake it, as this will greatly extend the lifespan of the optical power meter
2. Don't find it troublesome, make the adapter before using it
3. Before use, make sure the adapter is clean. If it is difficult to confirm, you can poke it on an alcohol swab dipped in alcohol
4. After use, press the dust cap securely
5. Although machines are designed with encapsulation, optical power belongs to precision instruments and should be avoided from collision
The above are some small issues that should be paid attention to when using it in daily life. Now we should talk about what to do if it cannot be changed after testing for a period of time.
1. Use a pointed cotton swab dipped in alcohol to wrap around the bald head and clean up any dirt inside.
2. Use a pointed toothpick to point the center of the bald head.
3. Currently, all optical power meters on the market come with manual calibration function
