Power-on and power-saving function
settings
The equipment will turn on
after pressing the " " key. Press
this button again for more than
two seconds to shut down.
This instrument has power
saving function, normal there is no
operation for about ten minutes
after booting, The device will
automatically shut down. If you need
a screen Shield this function to keep
the equipment working all the time
Status, just short press "on" when
booting Key, "Auto-off" at the bottom
left of the meter display. Disappearing
means that the power saving function
is cancelled.
Backlight control
In the power-on state, the
backlight will automatically turn off
after a period of time. After turning
off, press any key to activate the
backlight. The backlight is used to
illuminate the instrument display at
night or in dark places.
Wavelength selection
According to the needs of the
project, select the corresponding
wavelength to match the optical power
meter. After the meter is turned on,
press the "output wavelength" key, the
output wavelength and length will be
switched to the corresponding wave-
length in turn, and will be displayed on
the display. The laser light source of this
series can provide 1310nm and 1550nm
dual-wavelength laser output according
to demand.
Carrier output
In the actual project, it is necessary to
load the audio carrier in the optical signal
to identify the optical fiber. The equip-
ment contains three carrier frequencies,
which are 270Hz, 1KHZ, and 2KHz. After
pressing the "modulated carrier" key, the
equipment will load different carriers in
sequence, and the display will be
displayed at the same time. The current
carrier frequency will be displayed on the
screen.
