8.0.1 Fast charge protocol automatic detection
In this mode,The meter tries to trigger various protocols in
turn,Display the test results on the screen,Red is not supported,Green is
support,In the process of testing,Such as measuring PD chargers,It is
normal to restart and continue testing.During the test, it is forbidden to
connect to any equipment at the back end.
It does not respond to any key operation during the test. If you want
to exit during the test, please unplug the meter directly. After the test
is completed, click the middle button to start the test again; click the
BACK button to return to the previous page.
8.0.2 QC2.0 Trigger
In QC2.0 trigger mode, use the left and right keys to select the trigger
voltage, and click BACK to return.

20
8.0.3 QC3.0 Trigger
In QC3.0 trigger mode,Use the left and right keys to decrease/increase
the trigger voltage,Click BACK to return.Press the left/right keys to
quickly decrease/increase the voltage.
8.0.4 Huawei FCP trigger
The operation method is the same as QC2.0 trigger.
8.0.5 Huawei SCP trigger
The operation mode is the same as QC3.0 trigger
8.0.6 Samsung AFC trigger
The operation method is the same as QC2.0 trigger.

21
8.0.7 PD Protocol trigger
Switch the PD communication switch to ON, Enter the PD protocol trigger mode.
After exiting the PD trigger, switch the PD communication switch to OFF.
Take the picture as an example. The picture shows a message sent by a
charger.There are 6 gears in total, of which gears 1, 2, 3, 4, and 5 are fixed
voltage gears.The sixth gear is the adjustable voltage gear (PPS).
When the left dot stays on Gear,The gear can be switched by the left and
right keys. When the gear is switched to PPS gear,Then you can switch the
step voltage by clicking the middle button,After selecting the step voltage,
Through the left and right keys (left minus right plus),Decrease/increase
voltage.
8.0.8 PD Protocol conversion
This function is used for only QC2.0 charger,But want to supply power to PD
appliances.Before use,Switch the PD communication switch to ON,Then enter the PD
protocol conversion mode, after entering,Plug in PD appliances,You can perform
PD fast charge.
In this mode,Click the middle button and use the left and right buttons to
change the maximum power of packets sent by the PD.When changing power，Be
careful not to exceed the charger power to avoid unnecessary damage.After
changing the power, you must click the middle button to confirm.
Set 5V when no device is connected,Avoid high-voltage damage to mobile
phones that do not support high-voltage when plugged in.
QC2.0 only B type charger supports 20V trigger,So when the PD appliance
requests 20V voltage,The tester will detect whether the charger successfully
triggers QC2.0-20V,If it does not reach 20V,The tester will cancel the 20V gear,
And resend the Caps broadcast.
In addition,Some PD appliances will change the D+ and D- voltages
whencharging,Cause QC2.0 to trigger an exception,This type of PD appliances cannot
usethis function to charge.

23
8.0.9 VOOC/WARP Constant voltage trigger
The operation method is the same as QC3.0 trigger.
