• What does the 'S-E' error code mean on my YiHUA station?

  The 'S-E' error code typically indicates a sensor fault. This may mean the heating element or sensor module is damaged, or the handle is not correctly connected to the main unit.

• How do I calibrate the temperature on my YiHUA soldering station?

  Most digital YiHUA stations allow for digital temperature calibration. This is often done by pressing a specific combination of buttons (such as holding both the temperature increase and decrease buttons) to enter calibration mode, measuring the actual tip temperature with an external thermometer, and inputting that value.

• Why does my soldering station enter Sleep Mode?

  Sleep Mode is a feature designed to extend the life of the soldering tip and heating element. When the iron is idle in its holder for a set time, the temperature drops (usually to 200°C) to prevent oxidation and save energy. It wakes up immediately when the handle is picked up.

• Can I switch between Celsius and Fahrenheit?

  Yes, many YiHUA models feature a Celsius/Fahrenheit toggle. Refer to your specific model's user manual for the button combination or switch location to change the temperature unit display.
