Instructions

• The file system will be formatted at the first startup, which will take some time.
• Use click in the home screen to enter the burst heating mode.
• In the home screen, use double click to call out the PID menu.
• Press and hold in the home screen to open the menu.
• If there are multiple soldering tip configurations, the configuration selection menu will pop up on the home screen when the replacement of soldering tip is detected.
• When adding a new soldering tip configuration, the default parameter is empty. You need to calibrate the temperature and set the parameters yourself.
• Press and hold in the main menu to return to the previous level.

Function

Compatibility with heating systems

• ShenzhenT12
• Hot Bed (Other branches)
• High Frequency Welding Table (Theoretically)
• Hot Air Gun (Theoretically)

Basic function

• Support Utf 8 Input.
• Nulti stage PID control heating, multi terminal ADC / PID sampling period setting.
• Start up temperature, burst temperature and sleep temperature can be set.
• It can sleep and shutdown regularly, and customize the burst mode time.
• It can save tens of millions of groups of soldering tips configuration (10 groups by default).
• Dual sleep modes support: both vibration trigger and magnetic trigger are supported.
• English support

Advanced features

• PMOS and NMOS (default PMOS, because this option is dangerous, the setting needs to be modified on the source program).
• Shortcut key to quickly adjust PID.
• Two sets of PIDs are allowed for each soldering tip.
• Independent ADC / PID sampling period and Kalman filter parameters can be set through the menu.
• 9-stage soldering tip temperature fitting calibration.
• Temperature self calibration circuit (not implemented).
• Custom display effects: brightness, flip plane, transition animation, display style, list mode.
• Personalized Customization: prompt tone, encoder rotation direction, handle trigger mode, system language (only simplified Chinese is supported temporarily).
• Security settings: Customize startup password, undervoltage alarm, forced shutdown prompt and warning.
• Bluetooth remote command line control.
• Voice control (not implemented).
• Custom boot logo (not implemented).
