if you do not press a key within 10 minutes. Press the key for about two
seconds to deactivate the auto-off function and the indicator will disappear on
the LCD. The power meter powers off if the battery capacity is too low to
support operation.
4.3 Setting the Wavelength
Press the key repeatedly until the desired wavelength displays. Select from
six possible wavelengths: 850, 1300, 1310, 1490, 1550, and 1625 nm. The default
wavelength is 1550 nm.
The power meter defaults to the wavelength that you set in the last test.
When used with an optical laser source, the wavelength will shift according to the
laser source’s output wavelenth. Press and hold the key to activate auto-
wavelength recognititon.
