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.

1. Power meter mode
(1) ：Sequentially switching to the meter internal tested wavelength
(2) ：change among dBm、dB、XW in turn (image5-4)
Image 5-4
(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.
