v、Instructions for Use
When powered by dry battery, the bottom left corner of the instrument screen will
display Auto-off sign after turning on；if no other operations within 10mins, the
instrument will be off automatically, short press “ ” the auto-off will be
cancelled.
When using external USB adapter for power supply ，the instrument will have no
auto-off function.（image 5-1）
Image 5-1
After turning on, the instrument comes into “power meter mode”
automatically（image 5-2）， we can press“ ”button to come to“source
mode”（image 5-3）。
These two measurement modes can be used individually or simultaneously.

(3) ：
①Short press button，start REF function.
When the current tested value is set or changed to reference value, the instrument
comes to relative power measurement, and the top right corner of the screen will
show“Ref”
And the set dBm value。(image 5-5)
The relation of Relative power value, absolute power value and reference value：
Relative power value = absolute power value - reference value.

When the meter needs “System Zero”, the dust cap of the power meter detecting
port must be tightened to ensure no light input. And then long press this button
for about 5 seconds to have the automatic “System Zero” and the previous screen.

图5-11
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：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.
3. Backlight control function
With the instrument on,press“ ”button to open or close the backlight.
4. Battery power display
(1) if the battery icon becomes “empty”， it means the battery is to be exhausted and
reminds the user to replace the battery in time. (image 5-12)
(2) The user can use the attached USB adapter for power supply through Mini USB interface.
(image 5-13)
Image 5-12 Image 5-13
5. Frequency light detection
In the power meter mode, when the power meter detecting port receives the frequency
light input signal and it’s tested under the absolute optical power unit, the top right
corner of the screen will show HZ sign, indicating the current light signal frequency
is ***HZ.（image 5-14）
Image 5-14
Notes：When using the frequency detection function, A type optical power meter only
detects frequency with the power range more than -40dBm；C type power meter detects

frequency with the power range more than -20dBm.
6.Power meter calibration mode
In the power meter mode,press“ ”and“ ”， at the same time, “U-01”will
appear on the screen top right corner, indicating that the meter has come to power value
calibration mode. Press “ ”and “ ” to increase or decrease the absolute
optical power value. When the adjusted value is what you need, you can press “ ”
to save the current calibration value. After “----”appears on the screen, it means
the calibration is ok and then press “ ”to exit.(image 5-15)
Image 5-15
For example：take the 1310 wavelength calibration for an example：
①Select a high-stability 1310nm source, and then connect it to one end of patch
cord. The other end of the patch cord is inserted to the detecting port of the standard
power meter and tightens it. Choose 1310nm wavelength in the standard power meter,
and read the absolute optical power value, for example, we can set it for A.
②Removed from the detecting port of the standard optical power meter, patch cord
is inserted to the detecting port of the calibrated instrument power meter. Then
change the wavelength in the calibrated optical power meter to 1310nm. Press
“ ”and “ ” to increase or decrease the absolute optical power value
displayed on the calibrated instrument screen. When the absolute optical power value
on the calibrated instrument is A, press“”to save the current calibration
value. “----” on the screen indicates that the calibration is done.
③Other wavelength calibration is just like 1310nm wavelength，after calibration,
press“ ” to exit.
Note：All the meters have a rigorous calibration check in the factory. So the users
are better not to use this function to avoid the meter measurement deviation！
