306C Operating Instructions
To use the 306 remove the protective sheath, press the ON/DH (Data Hold) button and insert at least 1/2” of the stem into the testing area. Push the ON/DH button a second time and the temperature reading will automatically be held on the LCD display. “°F” (°C) will blink when DH is in operation. Pressing the ON/DH button a third time will return the 306 to normal operation. To save battery life, the 306 will automatically turn off after approximately 35 minutes.
Note: When turning the 306 on, the LCD will display the last reading before turning off for 2 seconds. Then it will display the current temperature.

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.
