The service manual is distinct from the operator’s manual. While the operator’s manual explains how to use the scale for daily tasks (weighing, printing labels, PLU management), the is intended for qualified technicians. Its primary goals are:
| Test Point | Signal | Expected Value | |------------|--------|----------------| | TP1 | VCC_IN | 9–30V DC | | TP2 | 3.3V out | 3.27–3.33V | | TP5 | 1.8V (core) | 1.79–1.81V | | TP8 | SIM_VCC | 3V or 1.8V (depending on SIM) | | TP12 | Module reset | 3.3V idle, 0V reset |
If the scale shows "Out of Zero" or inaccurate weights, you may need a software-based calibration.
