Press the ON/OFF button to end operation, or the unit will automatically power off after 35 minutes.

To reverse the LCD to suit your viewing angle:

Insert a small coin into notch in curved area “B”, then gently pry portion “A” from “B”. Shielded wires will keep the two parts connected. Twist the area “A” 180° and snap back into area “B”.

Get more accurate readings by using the right tip for your thermometer:

• Penetration: Use for immersion and air; air response time will be slower than if using anactual air probe.
• Chisel: Need chisel tip for surface temperatures. Penetration and/or air tips will not givean accurate surface reading.
• Air: Samples air temperatures three times faster than penetration or contact tips.
• Contact: Measures three times faster than chisel tip.
