Why does the laser on my Fluke 568 not work?

If your Fluke Thermometer's laser isn't working, the batteries might be low or dead, so try replacing them. Also, the laser may not function if the ambient temperature is above 40 °C (104 °F). Try using the thermometer in an area with a lower ambient temperature.
