Short press
button，the meter top right corner displays”--AU”to indicate
this function is started. Meanwhile, the laser output wavelength in the source module
will be switched automatically according to the change of the same wavelength in the
power meter module.
For example
For example
For example
For example：
：
：
：the meter internal source module has 1310/1490/1550 wavelength，the test
wavelength in the power meter module is 850/1300/1310/1490/1550/1625. If the test
wavelength in the power meter module is switched to 1550nm，the laser output wavelength
in the meter source module will be changed to 1550nm automatically；On the contrary,
when the test wavelength in the power meter module is different from the output wavelength
in the source module, the source module cannot follow automatically to change the
wavelength, and also no optical power output.
