Instructions

Magnification adjustment:

R7 and R5 are the magnification setting resistance (the default magnification is about 5 times for delivery, and the magnification can be changed according to your own needs. The resistance can be selected from 5k-47k. The greater the resistance, the higher the magnification. If the plug-in resistance is used, the original patch resistance can be removed and the plug-in resistance can be welded on the reserved pads at both ends of the patch position)
