[QUOTE="yiwai, post: 451066, member: 29373"] As shown in the attached picture, about the RTC chip,I adopted DS1302, which is directly inserted, and the load capacitance is 6pf, C47 C52 was not welded. [IMG]https://talk.electricianforum.co.uk/uploads/imageproxy/f0414229d0c0af543ca0962e670ab0c7.jpeg.65e432960e0ccfc803c7ad24542e0939.jpeg[/IMG] With 20ppm, the error is 2s/day. And then I tried again with 5ppm, the error had not changed. Is there any better way to improve the accuracy? [/QUOTE]
