Function Keys

  1. ON/OFF: press ON/OFF to turn it on. And press it for 3 seconds to turn it off. Under power-on
  2. mode, press this key shortly to activate or deactivate the 10-minute auto off function. The default setting is auto-off function ON when start the meter. Operators can press ON/OFF shortly to close the auto-off function.
    dBm/W: press dBm/W to enter absolute measurement mode. Press it repeatly to switch the display power unit between W and dBm
  3. λ:Switch the wavelength from 6 calibrated wavelengths, the current choice of wavelength will appears on the LCD
  4. VFL :press VFL to switch the VFL status, ON Glint or OFF. At the same time, the VFL status will be simultaneously displayed in the upper right corner of the LCD screen.
  5. Backlit is on when turning on the unit. It will turn off one minute later. Operators can press any key to make backlit for another one minute.


Turn on/off

Press ON/OFF shortly to turn on the unit. Press ON/OFF for a few seconds to turn it off and press this key slightly to activate or deactivate the auto-off function.

Absolute power measurement

  • Insert optical signal (Insert the pigtail properly), turn on the meter
  • Choose the wavelength via λ key. If the tested wavelength is not exactly same to the one in the power meter, then choose a close one from the power meter. For example, 1300nm wavelength is near to 1310nm, we can choose 1310nm to substitute 1300nm.
  • After the above steps, the LCD will show the test power value.

User self-calibration function

During the operation, when operators need to calibrate the meter to be accordance with other meters. So our product offers operators self-calibration function, the following steps will tell you how to do:

  • Press power key & dBm key at the same time, the instrument goes into manual calibration mode (at this time the four row units are all displayed).
  • Press λ key to choose the wavelength for calibration.
  • Now connect it with a pigtail which we already know its power and press REF or dBm/W to increase or decrease the power value by 0.05d every time. Until the LCD display the pigtail’s power (Or the difference gap less than 0.3db).
  • Short press power key to save calibration data (backlight will flash once).
  • Repeat above operation for other wavelength.
  • After recalibrate each wavelength, long press power key to exit calibration mode.

Auto off function 

The auto off is on when turning on the meter. Press ON/OFF  to activate or deactivate this function.

Visual Fault Locator function

  • Press VFL key, the VFL indicator is on, the locator output 650nm red laser.
  • Press the VFL key again, the locator and indicator are blinking at the same time, the frequency is about 2Hz, which is convenient to check line faults.
  • Press the VFL key the third time, then the VFL indicator is off, and the locator laser is off.

Replace battery

  • If the battery level is very low, please turn off the unit immediately and replace the batteries
  • Take out the batteries if not in use for a long period of time (like one month)
  • NOTE: do not charge the non-rechargeable battery, dangerous!


  1. Keep all optical connectors and surfaces free from oil, dirt or other contamination to ensure proper operation.
  2. Keep using the same type of connector
  3. Please cover the dust cap when not in use to keep the connector clean.
  4. Carefully plug in or out the adapter
  5. Regularly clean the connector.
  6. Take out the battery when not in use for a period of time.
