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.

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

Diagram Description: A wiring diagram shows the VAC8610F connected to a charger and a load. Wires are color-coded red for positive and green for negative. The diagram illustrates the connections for self-supply.

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 a positive value, whereas the measured current will show a negative value, otherwise the measured current will show a negative value.

(2) External power supply wiring instructions (red positive, green negative)

Diagram Description: A wiring diagram shows the VAC8610F connected to a charger, an external power supply (Vext), and a load. Wires are color-coded red for positive and green for negative. The diagram illustrates the connections for external power supply.

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.

(3) Charges relay wiring instructions (red positive, green negative)

Diagram Description: A wiring diagram shows the VAC8610F connected to a charger, an external power supply (Vext), a charging relay, and a load. Wires are color-coded red for positive and green for negative. The diagram illustrates the connections for the charging relay.

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.

(4) Discharge relay wiring instructions (red positive, green negative)

Diagram Description: A wiring diagram shows the VAC8610F connected to a charger, an external power supply (Vext), a discharge relay, and a load. Wires are color-coded red for positive and green for negative. The diagram illustrates the connections for the discharge relay.

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.

III. Display mode switching

The instrument has three display modes: full data mode, simple data mode, and voltage, current, and temperature curve display mode. To switch display modes: select the first item of cursor movement function, then click the upper key to switch the display mode. The instrument will remember the set selection mode.

Description: Green curve is voltage curve, red curve is current curve, and the orange curve is the temperature curve. The corresponding voltage range of the Y axis is V, 0-500. Current range is 0-500A. Temperature range is 0-100 degrees Celsius. When the measured data is too small (e.g., current is only 0.8A, making it not obvious in the curve), by adjusting the current curve magnification IYD to 50, the Y axis of the current curve is amplified 50 times, making the current curve more obvious. Voltage curves can be set using UYD for the same effect. Y axis coordinates have 270 points. The longest refresh time is 90 seconds. By setting a curve to record battery charge/discharge, intuitive performance judgment can be realized.
