# Menu System
|
|
|
|
In this firmware for these soldering irons, all settings are adjustable on the device itself. This means you do **not** require a computer to change any settings.
|
|
|
|
## Soldering mode
|
|
|
|
In this mode the iron works as you would expect, pressing either button will take you to a temperature change screen.
|
|
Use each button to go up and down in temperature. Pressing both buttons will exit you from the temperature menu (or wait 3 seconds and it will time out).
|
|
Pressing both buttons or holding the button near the USB will exit the soldering mode.
|
|
Holding the button at the front of the iron will enter boost mode (if enabled).
|
|
|
|
## Settings Menu
|
|
|
|
This menu allows you to cycle through all the options and set their values.
|
|
The button near the USB cycles through the options, and the one near the tip changes the selected option.
|
|
Note that settings are not saved until you exit the menu.
|
|
If you leave the unit alone (ie don't press any buttons) on a setting, after 3 seconds the screen will scroll a rough description of the setting.
|
|
|
|
The menu is arranged so that the most often used settings are first.
|
|
With submenu's being selected to enter using the front button (as if you were going to change the setting).
|
|
Scrolling through the submenu will return you back to its entry location after you scroll through all of the options.
|
|
|
|
### Calibrating input voltage
|
|
|
|
Due to the tolerance on the resistors used for the input voltage divider, some irons can be up to 0.6V out on the voltage measurement.
|
|
Please calibrate your iron if you have any issues with the cutoff voltage.
|
|
Note that cutoff messages can also be triggered by using a power supply that is too weak and fails under the load of the iron.
|
|
|
|
To calibrate your iron:
|
|
|
|
1. Measure the input voltage with a multimeter and note it down.
|
|
2. Connect the input to your iron.
|
|
3. Enter the settings menu
|
|
4. Under the advanced submenu
|
|
5. Select the calibrate voltage option
|
|
6. Use the front and back buttons to adjust the displayed voltage to minimize the error to your original measurement
|
|
7. Hold both buttons to save and exit to the menu
|
|
|
|
### Calibrating tip offset (Set tip model)
|
|
|
|
Some tips will have an offset on their readings, to calibrate this out perform the following steps:
|
|
|
|
1. Connect power to your iron
|
|
2. Make sure the tip is at room temperature (ie. wait for a fair while after using the iron before calibration)
|
|
3. Enter the settings menu
|
|
4. Scroll down to the advanced menu, and then the temperature calibration
|
|
5. Press the button to change the option (tip button)
|
|
6. The display will start to scroll a warning message to check that the tip is at ambient temperature!
|
|
7. Press the button near the tip of the iron to confirm
|
|
8. The display will go to "...." for a short period of time as the unit measures the tip temperature and the handle temperature and compares them
|
|
9. The display will then go back to *TMP CAL* and it will display a number, this is your offset number. You generally dont need it unless debugging issues
|
|
10. Calibration is done, just exit the settings menu as normal
|
|
11. You're done, enjoy your iron!
|
|
|
|
### Boost mode
|
|
|
|
This allows you to change the front key (one near the tip) to become a boost button when you hold it for > 2 seconds. This allows you to set this button to change the soldering temperature for short periods. For example when soldering a big joint and you want to boost the temperature a bit.
|
|
|
|
The boost temperature is set in the settings menu.
