be aware that the manual may be updated at any time. Please get the latest information on
the official website.
2.Overview
The FNB48USB tester is a high-reliability, high-safety USB voltage and current detection
meter and a mobile communication terminal fast charging trigger. It has a 1.77-inch
TFTLCD display and integrated USB-A, Micro-USB, Type-C interfaces. Uses a dedicated
16-bit ADC, PD protocol physical chip. It can be used to measure the power supply or power
consumption of products such as USB interfaces, mobile phone chargers, U disks, etc.; it
can be used to measure mobile phone charging power and mobile power input and output
conditions; it can be used for charger fast charging protocol testing.
This instruction manual includes relevant safety information, warning tips and solutions to
common abnormal situations. Please read the relevant content carefully and strictly abide
by all warnings and precautions.
3.Safety Precautions
●Do not connect the monitoring interface to a power supply exceeding 24V.
●Do not connect the PC connection port to a power source exceeding 16V.
●Only one pair of monitoring interfaces (one input port, one output port) can work at the
same time. When there is a pair of monitoring interfaces working, it is forbidden to
connect to the equipment on other monitoring interfaces. (Except the PC connection
port, the PC port can be connected to an external power supply.)
●When using the fast charge trigger module, please do not connect equipment that
cannot withstand high voltage to any monitoring interface.
●After using the PD trigger/monitor/conversion/read E-Marker cable function, please turn
the PD communication switch in the lower right corner back to the OFF position.
●When working at high power,the temperature of the instrument rises.Please be careful to
prevent burns.

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.

SuperVOOC requires a load greater than 500mA on the back end to deceive, And
SuperVOOC only has a voltage of 10.5V.Therefore, you can only press BACK to return
to the page, and there is no other operation.
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

supply not greater than 16V (usually 5V) and a
Micro-USB cable,Connect the PC online port,Provide
external power.
●Use the PD listener function, need 2 C-C cables,
connect the charger and PD electrical appliances
from the Type-CIN interface and Type-COUT interface
respectively. When the connection is normal and the
PD protocol triggered by the PD consumer is
captured, the page is represented as shown. When
the PD charger cannot be powered, because the C-C
cable has only one-sided CC， and the 2 CCs are not
connected, you can flip one of the C-C cable
connectors，to solve the problem.

●E-Marker cable refers to a cable with an E-Marker chip in the Type-C interface,If the
interface does not contain E-Marker chip.The packets from the PD charging head
cannot exceed 3A current,and only use the E-Marker cable to trigger the PD
protocol,the current can exceed 3A.
●When using PD listener,except that the Type-C interface cannot be used for power
supply,PC port, USB-A, Micro-USB interface can all be used for power supply.The PD
communication switch needs to be turned ON.
The two pictures above,the picture shows the parsed data,the second picture is the
original data,Users can consult the relevant information of the PD agreement by
themselves,do your own comparison.
【 10.0.2 】 Read E-Marker cable
●After entering this function, From
any Type-C interface, plug in the
cable. You can read the message,As
shown below.
●Click the middle button to switch

【 10.0.3 】 Read DASH cable
●Enter this function,plug in the DASH cable,you can
read the chip-related data,as shown below.
【 10.0.4 】 Analog DASH cable
This function is used without DASH cable
●The USB-A head of the DASH cable will have one more data pin than the ordinary
USB-A data cable.And one more chip,used to identify and start VOOC/WARP flash
charge.
●If the phone normally needs to use a USB-A->Type-C DASH cable,but there is no such
thread in hand,only FNB48 tester and a C-C cable,but want to trigger VOOC/WARP
flash charge.At this time, the function of simulating DASH cable can be started,and
use the C-C cable to connect to the phone, you can perform VOOC/WARP flash
charging.
※Note:Since this method does not use the original data cable for charging, the
charging power is largely affected by the C-C line.If the impedance of the C-C line is
high,then the charging power will be reduced a lot.
【 10.0.5 】 Apple 2.4A acceleration
When the Apple device detects that the charging head D+ and D- are 2.7V,to charge at
5V-2.4A,this function sets D+ and D- to 2.7V.
