Wiring instructions video: https://youtu.be/Hjj9fkyuNp0
(1). Self-powered wiring method
If the voltage range of the tested battery is between 10-120V during
normal operation,self-powered wiring can be used. First, turn the power supply
selection interface switch to "2W", and then connect the positive terminal of the
battery to the power supply interface "Vsns" , This line does not need to be
particularly thick,13-16AWG wire is fine. Pay attention to the positive and
negative poles of the battery, do not connect the wrong or reverse connection.
The negative pole of the battery is connected to the screw with the battery
“BATT-” on the sampler, and the negative pole of the charger and the negative
pole of the load are connected to another screw of the sampler. It is better to
use a copper nose to connect it firmly. When charging, the current direction
symbol color is red, and the remaining capacity value increases. When
discharging, the color of the current direction symbol is sky blue, and the
remaining capacity value decreases.

3.Communication protocol control
We only provide communication protocol, customers can carry out
secondary development according to communication protocol.
1.Overview
The command line is used as the control command, and the
communication rate is 115200. The PC sends out the command, the meter
22
Page 27
Hangzhou Junce Instruments Co., Ltd.
parses and executes it, and then returns the result to the PC. The different
commands are described below.
The sending data format is as follows：
Start bit Function code Function No. Connector Address symbol Spacer
： W,R 00~99 = 1-99 ,
Checksums Spacer Data field Spacer Terminator
1-255 , See instructions , <CR><LF>
Explain:
(1) Function code: "W" is the write instruction used to set various parameters,
and "R" is the parameter used by the read instruction to return to the machine.
(2) Function No.: different values represent different parameter settings.
(3) Address symbol: address range is 1-99, 0 is broadcast address.
(4) Checksum: the value of the sum is obtained by adding 1 to the remainder of
255 after the sum of all the numbers after the check sum. If the sum of the
check is taken as 0, it means that it is not verified.
(5) Data field: the data field is equivalent to the number of operations of the
command. For example: W20=12162000, the instruction operands are 2000,
which means that the over voltage protection is set to 20.00V.
(6) Terminator: Each instruction ends with a carriage return + line feed, and
<CR> represents the carriage return in the ASCII character table (hexadecimal
representation is 0x0d). <LF> is the newline character in the ASCII character
table (in hexadecimal notation is 0x0a). The above two methods indicate
carriage return and line feed.

Description of full power voltage, power deficit voltage, full power current, and
detection time:
For example, for a 12V400Ah lead-acid battery, set the full voltage to 14.4V
and the full current to 2%, which means that the full current is 400*0.02=8A,
and the detection time is set to 2 minutes, which means that during the
charging process, when the voltage is higher than 14.4 V. After the charging
current is lower than 8A and the duration exceeds 2 minutes, the percentage of
remaining capacity will be automatically adjusted to 100%;
Set the power-loss voltage to 10.5V and the detection time to 2 minutes, which
means that when the voltage is lower than 10.5V during the discharge process
and the duration exceeds 2 minutes, the percentage of remaining capacity will
be automatically adjusted to 0% (if you feel that the power-loss voltage is this If
the function is not very practical, you can set the full voltage, full current, and
detection time without setting the voltage deficit);
