Wiring

Self-supply wiring instructions (red positive, green negative)

Note: if the voltage range of the battery (power supply) under test is between (8-100V), the jumper cap of the power supply selection interface can be adjusted to “2W”first. Connect the positive and negative electrodes of the battery (power supply) tothevoltage measurement port “+Bat-“; If the current direction of the current flowingthrough 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

External power supply wiring instructions (red positive, greennegative)

Note: if the voltage range of the battery (power supply) is not between (8-100V), 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 withthe arrow direction on the Hall sensor, the measured current is positive and negative.

Charges relay wiring instructions (red positive, green negative)

Note: the working power of the relay is provided by external power supply, if therelay is connected, it should provide an external power supply with the same workingvoltage 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.

Discharge relay wiring instructions (red positive, green negative)

Note: the working power of the relay is provided by external power supply, if therelay 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

Wiring

Select the appropriate wiring method according to the range of the measuredv oltage 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.
