Introduction


Replacing the battery in your ThermoWorks BlueTherm One or TempTest Blue thermometer is an easy process -but it has to be done carefully.



Process


Steps for the "BlueTherm One" Thermometer


Needed Items:

  • (1) Phillips Screwdriver
  • (1) AA Battery -please use a quality lithium battery for best performance and longevity.



Battery Replacement:

  • Remove protective rubber boot if applicable.
  • Unscrew the 4 screws located on the rear of the instrument and remove rear case.
  • This can be difficult especially after a long period, but if done gradually, at each corner, the case will come apart. Be careful not to cut or pinch the rubber seal. Flip the lid upwards once loose.

  • Replace the "AA" battery -noting polarity.


  • Refit rear case and refit screws taking care not trap/pinch the seal. 

  • Tighten the screws evenly but do not over-tighten as this will affect the instrument's water resistance.
  • Ensure the battery status icon in the upper-right corner shows a full battery.


NOTE: Typically, users will remove the stainless steel probe prior to replacing the battery. If "ERR" is shown after replacing the battery, simply re-insert the stainless steel probe back into the thermometer.
