INSTRUCTIONS: 1. PH2.0 terminal products supporting the use of wire, connected to the circuit board face should plug back. 2. External NTC temperature sensor, please put the sensor to measure the temperature of the parts, do not squeeze the sensor( selective assembly). 3. Red line to the positive terminal, black line to the negative terminal. 4. After the instrument is powered on , which shows the percentage of the battery power, the voltage value, and the symbols of the analog battery. 5. Press the button to turn off the instrument. In close mode, you can wake up the instrument by pressing any button. 6. Click the button , you can switch the voltage value and temperature value display. 7. The battery symbols on the display interface, from the right to the left, are 7 display boxes representing the pool power from low to high. 8. The voltage on the display interface is measured in real time, and the voltage value is displayed on 10-100V. 9. The percentage on the display interface is the percentage of the remaining battery power 10. When the battery is connected to the charger or the discharge of the high current load, the display parameters will fluctuate 11. The red lightning flashes the alarm when the battery is low 12. Low voltage buzzer alarm(Selective assembly) 13. If the battery specification is special, you can enter the set mode 3-- and reset the upper and lower limits of the measured battery voltage. Package included: 1x Battery Monitor 1x Cable Notice: Please allow 1-3cm error due to manual measurement and make sure you do not mind before ordering.
