A multimeter user manual that introduces the measurement methods and precautions of multimeters.
The guide introduces the symbols on the dial, the function of knobs and selector switches, and how to set the appropriate range for the quantity being measured. It also covers the correct use of input jacks, switching positions, and the importance of not mixing voltage, current, and resistance settings.
Detailed procedures are provided for measuring AC/DC voltage, DC current, and resistance, including probe connection methods, polarity considerations, and reading interpretation. Safety notes emphasize avoiding live switching, selecting proper ranges, and proper storage after use. This manual is written in Chinese.
| DC Voltage Range | 1 V – 500 V |
|---|---|
| Current Range | 50 µA – 500 mA |
Set the switch to the DC current position, choose the appropriate current range, disconnect the circuit, then connect the multimeter in series so current flows from the red probe to the black probe.
Never measure resistance on a live circuit; ensure the multimeter is powered by its internal battery and the circuit is de‑energized before connecting the probes.
