Use tips:
1, the kit supply voltage is voltage 5V, try to use a power supply with fewer stray waves and stable output.
2, each before powering , all switches should -, and power about 2 seconds before the display.
3, after the display, before installing the shell, adjust the potentiometer so that the voltage between pin 4 and pin 5 of the LM393 is 3.16V.
4, measure what components are rotated to the corresponding gear.
5, measurement of non-polarized capacitance, inductance does not distinguish between positive and negative, frequency and electrolytic capacitors to distinguish between positive and negative contact to determine good.
6, the tail number of the readings are not rounded and fictitious optimization, all the tail number has jumped is normal.
Whether with a shell: with Case
