if the current over the rated range ,fuse will melt to protect the meter .Pls use the same model when
change the fuse, Pls opens the battery cover to change.
Note: 10A socket without fuse protection, if over the current range.
Wrong using the 10A socket to measure the voltage, will damage the meter.

Optical power meter
Click icon to enter ,with five wavelength 1625nm,1550nm , 1490nm , 1310nm ,1300nm ,
850nm ,linear or nonlinear optical power display, both for optical power testing and Fiber link loss
relative measurement . It is necessary tool for installation and maintenance optical fiber communication,
cable television and CCTV security system.
Note: Please keep the fiber connector and the dust cap be clean, and clean the detector with the
special alcohol.
Data hold
While testing, click “Hold” to data hold, the data will not change. It’s convenient to read. Press
again to quit.
Relative power value (optical link loss) measurement
While testing, set the wavelength for measurement. Click “relative”(difference) to test, the tester Auto
save current fiber power value as the base reference value. Input another optical fiber to be measured,
