Tutorial: How to use Digital Voltmeter and Ammeter YB4835VA

This digital voltmeter and ammeter is ideal for measuring voltages and currents in high-power circuits. Useful for makers and technicians working with batteries and loads.

What you need

• Digital Voltmeter and Ammeter YB4835VA
• Connection Cable
• 10kΩ Resistor (for protection)
• Circuit to Test

Steps

1. 1. Check the datasheet for the specifications of the circuit to test.
2. 2. Connect the power cable to the voltmeter.
3. 3. Set the mode (voltmeter or ammeter) with the button.
4. 4. Connect the 10kΩ resistor between the voltmeter and the circuit.
5. 5. Connect the circuit to test.
6. 6. Read the voltage or current on the display.
7. 7. Check the datasheet for further settings.
8. 8. Turn off the circuit at the end of the measurements.

Mini project

Build a battery charger balancer using the YB4835VA to monitor the voltage.

Common mistakes

• Connect the voltmeter directly to a potential circuit without a protection resistor.
• Set the wrong mode (voltmeter instead of ammeter or vice versa).
• Omit reading the datasheet for further settings.
• Do not turn off the circuit at the end of the measurements.

Recommended accessories

• Battery Charger Balancer
• Overcurrent Protected Circuit
• 1kΩ Resistor
• Batteries to Test
