How do I set the temperature scale to Celsius/Fahrenheit?
- Open the battery door and remove the batteries. Once you have removed the batteries, you will be able to access the C/F switch.
- Slide the switch to C or F using a pen or pointed object.
- Place the batteries back into the thermometer, snap the battery door back on, ensuring that it is in the original latched position.
- You will see your chosen temperature scale symbol - Celsius or Fahrenheit - on the display.
My thermometer displays the wrong temperature scale, but I did not change it.
If you have ever changed the batteries, it is possible that the C/F switch may have accidentally been bumped. Alternatively, if you have not changed the batteries and the temperature scale is wrong, it is still possible that the switch has somehow been adjusted. Simply follow the steps outlined above. If this still does not fix the issue, contact us for further assistance.
