How does the HY128B work? The HY128B is an intelligent digital multimeter ideal for accurately checking and measuring various electrical parameters. Useful for beginners and intermediate makers.

What do you need?
– HY128B Digital Multimeter
– Power source (e.g., AA battery)
– Components to measure (e.g., resistor, voltage)
– Test leads

Steps:
1. Turn on the multimeter by pressing the power button.
2. Connect test leads to appropriate positions on the multimeter.
3. Select measurement type (voltage, current, resistance, etc.) using the menu.
4. Connect test leads to the circuit being measured.
5. Read the result from the screen.
6. For voltage measurements, select an appropriate scale.
7. For current measurements, use continuous measurement mode.
8. For resistance measurements, use contact mode.
9. Verify high precision true value readings on the color screen.
10. Turn off the multimeter when not in use.

Mini-project: Build a simple circuit with a variable resistor and measure voltage at its end using the HY128B.
Common mistakes:
– Not selecting the correct scale for measurement.
– Reading values from the screen while test leads are still connected.
– Using test leads as long-term connectors.
– Measuring direct current on an unprotected power source.

Recommended accessories:
– AA batteries
– Test leads
– Variable resistor
– Power supply
