Question 1

Do I need to calibrate the SANITAS SFT 75 thermometer after changing the batteries?

Accepted Answer

No, no calibration is necessary after changing the batteries.

The SANITAS SFT 75 thermometer is factory pre-calibrated and maintains its calibration regardless of battery replacement. When you change the 2 AAA 1.5V batteries located in the compartment at the back of the device, the existing calibration is not affected and remains valid.

If you suspect inaccuracy: The thermometer displays an accuracy of ±0.1°C. If the measurements seem abnormal after changing the batteries, please consult SANITAS customer service rather than attempting to recalibrate it yourself. Specific calibration instructions are only provided by the manufacturer if necessary.
