IV. Wiring
(1) Self-supply wiring instructions (red positive, green negative)
Note: if the voltage range of the battery (power supply) under test is between (8-100
V), the jumper cap of the power supply selection interface can be adjusted to "2 W"
first. Connect the positive and negative electrodes of the battery (power supply) to the
voltage measurement port "+Bat-"; If the current direction of the current flowing
through the Hall sensor is the same as the direction of the arrow on the Hall sensor,
the measured current will show positive value, whereas the measured current will
show negative value, otherwise the measured current will show negative value

7
（2）External power supply wiring instructions (red positive, green
negative)
Note: if the voltage range of the battery (power supply) is not between (8-100 V),
the jumper cap of the power supply selection interface can be adjusted to "3 W" first.
Connect the positive and negative poles of the battery (power supply) to the negative
pole of the external power supply. Do not misconnect or reverse the positive and
negative electrodes of the battery (power supply). Connect the positive electrode of
the battery (power supply) to the negative electrode of the load through the Hall
sensor. When the current direction flowing through the Hall sensor is consistent with
the arrow direction on the Hall sensor, the measured current is positive and negative.

8
（3）Charges relay wiring instructions (red positive, green negative)
Note: the working power of the relay is provided by external power supply, if the
relay is connected, it should provide an external power supply with the same working
voltage as the relay. Connect the control port of the relay to the charging controller
interface, if you want to control the charging positive pole, pass the positive pole
through the relay, and if you want to control the charging negative pole, connect the
negative pole to the relay. When the relay is sucked, the “IN”lights are lit and
extinguished as a hint.

9
（4）Discharge relay wiring instructions (red positive, green negative)
Note: the working power of the relay is provided by external power supply, if the
relay is connected, it should provide an external power supply with the same working
voltage as the relay. Connect the control port of the relay to the interface of the
discharge controller. If you want to control the positive electrode of the discharge,
pass the positive wire through the relay, and if you want to control the negative
electrode of the discharge, connect the negative wire to the relay. When the relay is
sucked, the “OUT”lights are lit.

Chapter III Description of use
I. Wiring
Select the appropriate wiring method according to the range of the measured
voltage to ensure that the input voltage is within the range of the instrument. The
external power supply voltage is 8-60V, and the measured voltage exceeds 70V. It is
better to use independent power supply for the display screen to reduce the power
consumption of the motherboard.
Note: Self-supply detection voltage range :8V ~100V;
Test voltage range for external supply :0V ~120V;

III. Display mode switching
The instrument has three display modes: full data mode, simple data mode,
voltage, current and temperature curve display mode. The method of display mode
switching: select the first item of cursor movement function, then click on the upper
key to switch the display mode, and the instrument will remember the set selection
mode.
Description: Green curve is voltage curve, red curve is current curve, The orange
curve is the temperature curve, The corresponding voltage range of the Y axis V,0-500
Current range 0-500A, Temperature range 0-100 degrees Celsius, When the measured
data is too small, For example, the current is only 0.8A so it is not obvious in the
curve, By adjusting the current curve magnification IYD to 50, Amplify the Y axis of
the current curve 50 times, So the current curve is more obvious. voltage curves can
be set UYD to achieve the same effect. Y axis coordinates have 270 points, The
longest refresh time is 90 seconds, By setting a curve to record a battery charge
discharge, Realize intuitive performance judgment.
