Use Notice: 1. The power supply voltage of the kit is 5V DC. Try to use a power supply with less noise and stable output. 2. Before each power-on, all switches must be flipped up, and the display will not appear until about 2 seconds after power-on. 3. After displaying, before installing the case, adjust the potentiometer so that the LM393 is between pin 4 and pin 5. The voltage is 3.16V. 4. Rotate to the corresponding gear according to the component being measured. 5. When measuring non-polar capacitance and inductance, there is no distinction between positive and negative poles. Frequency and electrolytic capacitance must distinguish between positive and negative poles. Contact should be determined and good. 6. The mantissas of the readings are not rounded or blurred. It is normal for all mantissas to jitter.
