Instruction Manual

Features

The HarborShield™ Infrared Thermometer measures temperature by collecting the infrared heat radiating from a surface. The thermometer can measure both the human body and surface temperatures. The thermometer has a one-second read time and automatically shuts off after 15 seconds of inactivity.

• 1 second read time
• Select Fahrenheit (ºF) or Celsius (ºC)
• Auto shut off
• Accuracy ±0.2ºC/±0.4ºF
• Historical readings logged in memory
• FDA registered

Infrared thermometers are designed to measure surface temperatures and NOT the internal temperature of food or other materials. Food temperatures can only be accurately and safely taken using a probe thermometer designed specifically for cooking.

Infrared thermometers are widely used in manufacturing processes, HVAC, and concrete.

Setup

Insert Batteries

1.  Open Battery cover located on the bottom of the thermometer handle.

2.  Insert 2 “AAA” alkaline batteries (not included) following the positive and negative connection indicators on the batteries.

3. The thermometer will “Beep” once when batteries are inserted correctly.

Set Temperature Units (ºF / ºC)

1. Pull the trigger on the thermometer and quickly release it to turn the thermometer on. 
2. Press the “Setup” button on side of the thermometer for 2 seconds and release.
3. F1” appears on display for Fahrenheit units. To select Fahrenheit units, pull the trigger. For Celsius units, go to the next step.
4. To select Celsius units, press the (-) button on side of the thermometer.
5. Press the “Setup” button to save.

Using the Thermometer

Take Temperature

1.  Slide switch on side of thermometer to Body or Surface Mode.

2. Point the thermometer at the forehead or another surface.
   • For accurate body temperature, hold thermometer 2-4 in. from the forehead.
   • For accurate surface temperature, hold thermometer 2-4 in. from the surface.

3. Press the trigger and release after 1 second when you hear a “Beep”.
   • Thermometer will sound “Beep” alerts for a few seconds when Body Temperature exceeds 100.4ºF (38ºC).
   • Color-Coded Display (Body Mode only)
   Green – Reading is between 95ºF and 99ºF.
   Yellow – Reading is below 95ºF (”Lo” warning appears and thermometer beeps for a few seconds). Or, reading is between 99ºF-100.4ºF.
   Red – Reading is between 100.4ºF and 107.6ºF. “Hi” warning if the temperature is over 107.6ºF.

Using the Thermometer
(Continued)

View Temperature Log History

1. Take temperature by pulling the trigger.
2. Press (-) button on side of thermometer to view previous temperature readings that have been stored in memory.
3. Press (+) to advance to the most current temperature reading.

Turn Audible Alert ON/OFF
Follow these steps to turn the audible “Beep” alerts ON or OFF.

1. Pull the trigger to activate the thermometer.
2. Press the “Setup” button on the side of the thermometer for 2 seconds and release.
3. “F1” appears on display. Press the “Setup” button 3 times until “F4” appears on display.
4. Press “+” button to turn the sound alert ON (Alert Icon appears on display home screen) or press the “–” button to turn the sound OFF (alert icon disappears from display).
5. To save, press the “Setup” button until “OFF” appears on the display.

Accuracy

Infrared thermometer accuracy may be affected by:

• Frost, moisture, dust, fog, smoke, particles in the air, or extreme temperature and/or humidity.
• Air conditioning or fans blowing nearby.
• Rapid changes in ambient temperature.
• Dropping the thermometer.
• Proximity to a radio frequency with an electromagnetic field strength of 3 volts per meter or greater.

Cautions & Limitations

• Do not immerse in water. The thermometer is not waterproof.

• Use caution around extremely hot surfaces and open flames.

• IR thermometers are meant to measure surface temperature and NOT the internal temperature of food.

• Thermometers cannot measure the temperature of objects immersed in liquid or underwater. The temperature reading will be of the liquid itself.

• Thermometers cannot measure the temperature of objects through transparent surfaces (ex. windows). Temperature reading will be of the glass surface and not the area
  beyond.

• Remove batteries during long periods of inactivity.
