This thermometer is giving ear readings about 2°f low. Is there any way to recalibrate it (checked against another thermometer)

The manual does not mention a specific recalibration procedure for the Silvercrest SFT 81 thermometer. However, you can try the following steps to ensure accurate readings:

1. Check for Obstructions: Ensure the ear canal is clean, as earwax can affect measurements.
2. Proper Positioning: Pull the ear gently up and back to align the sensor with the eardrum.
3. Allow Time for Adjustment: If you were lying on your ear, wait a few minutes before measuring.
4. Clean the Sensor: Wipe the sensor tip with a soft cloth dampened with antiseptic after each use.
5. Check Battery: Replace the battery if necessary, as low power may affect accuracy.

If the readings remain inconsistent, contact the specialist dealer or service address for further assistance.
