Keep the thermometer straight and point it directly at the target. Angles can cause wrong temperature results.
Avoiding Obstructions
Make sure nothing blocks the thermometer’s view. Dust, dirt, or glass can change the reading. Clean the lens regularly to keep it clear.
Remove items like plastic wrap or clothes from the target area. These can reflect heat wrongly.
Taking Multiple Readings
Take several readings from the same spot. This helps confirm the temperature is correct. If results vary, try again after a few seconds.
Use the average of the readings for more reliable results.
Calibration And Maintenance Tips
Calibration and maintenance keep your infrared thermometer accurate and reliable. Without regular care, the device may give wrong readings. Simple steps can prevent errors and extend the tool’s life.
