If you feel that the default magnification is not appropriate, you can change the magnification by yourself as follows:
How to adjust magnification:
R7 and R5 are the magnification setting resistors (the default delivery is about 5 times magnification, you can change the magnification according to your own needs, the resistance can be selected from 5k-47k, the greater the resistance, the higher the magnification, if you use plug-in resistors , You can remove the original chip resistor and solder the plug-in resistor on the pads reserved at both ends of the chip position)
Specification:
