Xin Zhi Zhao Schematic — Updated Overview and Key Changes
This post summarizes the updated Xin Zhi Zhao schematic, highlights important changes, and explains practical impacts for designers and maintainers working with the new revision.
Step 2 – Signal Chain Calibration
- Short input to ground → adjust offset trimmer to read 0V at ADC input.
- Apply known reference signal (e.g., 1kHz square wave, 1Vpp) → adjust gain potentiometer for expected output.
Dual-Open Intercommunication: This feature allows technicians to open a bitmap and its corresponding schematic simultaneously. Clicking a component in the bitmap automatically highlights it in the schematic, and vice-versa. xin zhi zhao schematic updated
