Tutorial: How to use the Digital Multimeter HY128C
The digital multimeter HY128C is an essential tool for makers and electricians who want to measure currents, voltages and resistances accurately. With its large thin colour display, it makes readings clear and intuitive.

What do you need?
– Test Leads (optional)
– Variable Resistors
Steps:
Firstly, consult the multimeter manual to familiarise yourself with its buttons and functions. Select the correct mode on the multimeter based on the measurement you want to perform (DC or AC voltage, current, resistance). Connect the test leads to the multimeter and to the points of the circuit under test. Press the measurement button to start the reading. Check the product datasheet for specific units of measure. If working with Arduino, connect the device pins to the board and use the provided sketch to read values from the multimeter. Remember to disconnect the multimeter before changing configuration or mode. After each use, turn off the multimeter to save battery.
Keep electrodes and connectors clean on the multimeter for accurate measurements.

Mini-project: Create a home current-sensitive alarm system. Connect the multimeter to an electrical socket, using Arduino to monitor any current variations that may indicate a short circuit.

Common Mistakes:
– Not selecting the correct mode before measurement.
– Forgetting to turn off the multimeter after use, wasting batteries unnecessarily.
– Using damaged or dirty electrodes, compromising reading accuracy.
