2、Overview
The FNB58USB tester is a high-reliability, high-safety USB voltage andcurrent
detection meter and a mobile communication terminal fast chargingtrigger.It has a
2.0-inch full-color ultra-wide viewing angle TFT LCD display, integrated USB-A,
Micro-USB, Type-C interface. Use external 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, and U disks; it can be used to measure the charging
power of mobile phones and the input and output of mobile power supplies; it can be
used to test the fast charging protocol of chargers.
This instruction manual includes relevant safety information,warningtips and
solutions to common abnormal situations. Please read the relevantcontent carefully
and strictly abide by all warnings and precautions.
3、 Safety precautions
● Do not connect the monitoring interface to a power supply exceeding 28V;
● Do not connect the PC connection port to a power source exceeding 16v;
● Only one pair of monitoring interfaces (one input port,one outputport) can work at
the same time. When there is a pair of monitoringinterfaces working, it is forbidden
to connect to the equipment onother monitoring interfaces. (Except the PC
connection port, the PCport 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 cablefunction，please
turn the PD communication switch in the lower rightcorner back to the OFF position;
● Do not charge the phone after the fast charge is triggered, Therefore,the phone is
damaged,the manufacturer is not responsible for any damage to the phone.

can be selected from 1-10 groups. The time, capacity and energy are counted and
displayed in order from top to bottom on the right side of the selected group
number.
3. The battery voltage, the default is 3.7V, this parameter can be selected from 3.0-5.0V,
the actual value please refer to the relevant information.
4. Conversion efficiency is energy conversion efficiency, the default is 90%, this
parameter can be selected from 80%-100%, the actual value should be set according
to the actual conversion efficiency of the battery.
5. The red letter is the calculation result. If you want to get the result in mAh, please
convert it by x1000

Measurement steps
1. Connection method: charger + FNB58 + constant
current load (the current is adjusted to about
0.5-1A), press the middle button to record the
reference value.
2. Connection method: charger + cable + FNB58 +
constant current load (the current should be
adjusted to about 0.5-1A, which should be similar to the current when the reference
value was recorded), the system automatically calculates the internal resistance of the
cable.
FNB58 uses the differential pressure method to measure the internal resistance of
the cable, which needs to be used with a constant current load.
Click the middle button: use the current voltage and current value as the reference
value.

10.0.2 PD Listener
When using PD listener,Need to turn the PD communication switchtoON,And use a
power 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 chargerand PD electrical
appliances from the Type-CIN interface and Type-COUTinterface respectively.When
the connection is normal and the PD protocoltriggered by the PD consumer is
captured,The page is represented asshown below.
Note：
1 Open the settings menu -> trigger -> block PDCRC, you can turnoffthe monitoring of
CRC.
2 For the meaning of various messages in the PD protocol, pleasereferto the relevant
information..
The figure below,The charger is a 65W PD charging head,The currentPD appliance
chooses the second gear,Trigger the target voltage 9V,Maximum current 3A.
When the PD charger cannot be powered,Because
the C-C cablehas only one-sided CC,And the 2 CCs
are not connected,So you can flipone of the C-C
cable connectors,Solve the problem.

●This function is used for only QC2.0 charger, But want to supply power to
PDappliances.
●Before use, Switch the PD communication switch to ON, Then enter the PDprotocol
conversion mode,after entering,Plug in PD appliances, You can performPD fast
charge.
●In this mode,C1ick the middle button and use the left and right buttons tochange the
maximum power of packets sent by the PD.When changing power，Becareful not to
exceed the charger power to avoid unnecessary damage.Afterchanging the power，
you must click the middle button to confirm.
●Set 5v when no device is connected,Avoid high-voltage damage to mobilephones
that do not support high-voltage when plugged in.
●QC2.0 only B type charger supports 20v trigger, So when the PD appliancerequests
20V voltage, The tester will detect whether the charger successfullytriggers
QC2.0-20V,If it does not reach 20V, The tester will cancel the 20V gear,And resend the
Caps broadcast.
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 thePD 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 the USB-C electronic label,Except that the Type-C interface cannot be used
for power supply,PC port，USB-A，Micro-USB interface can all be usedforpowersup-
ply.The PD communication switch needs to be turned ON.

themselves,Do your.
●This function is used without DASH cable.
●The USB-A head of the DASH cable will have one more data pin thantheordinary
USB-A data cable.And one more chip,Used to identify and startVOOC/WARP flash
charge.
After entering this function,From the output
Type-C interface,Plug in thecable,You can
read the message,As shown below:
Click the middle button to
switch to the figure below:
Enter this function,Plug in the DASH cable,You can read the chip-related data,As shown
below:
10.0.5 Read DASH cable
10.0.6 Soft DASH Cable

●If,The phone normally needs to use a USB-A->Type-C DASH cable,Butthere is no such
thread in hand,Only FNB48 tester and a C-C cable,Butwantto trigger VOOC/WARP
flash charge,At this time, the function of simulating DASH cable can be started,And
use the C-C cable to connecttothe phone, You can perform VOOC/WARP flash
charging.
Note: Since this method does not use the original data cable forcharging, The
charging power is largely affected by the C-C line,If theimpedance of the C -C
line is high,Then the charging power will be reduced a lot.
