Instruction Manual

Introduction & classification

This is a Non-Contact Forehead Thermometer applicable to forehead measurement. The thermometer measures body temperature by collecting heat radiation emitting from the forehead. A new probe structure is adopted in this thermometer. It’s simply operational, Hygeian, reliable, and highly accurate. Users can get a precise reading within one second with one touch. This thermometer is cost-effective and is widely used in schools, customs, hospitals, and for family use. Intended Use & Indication for use: The Non- Contact Forehead Thermometer is an infrared thermometer intended for the intermittent measurement of human body temperature in people of all ages.
This thermometer is classified as a Class IIa(for CE)/class II(for FDA) Medical Device, sorted as internally-powered equipment and type BF application device. It’s prohibited to use this thermometer in flammable anesthetic gas or gas mixture of air and oxygen or nitrous oxide. This is continuous operation equipment.

Working principle

Any object can generate a certain proportion of infrared radiant energy as per its own temperature. The radiant energy and its wavelength distribution are subjected to its surface temperature. Based on this principle, this thermometer is designed to detect infrared radiation at 5~14um by a highly precise infrared sensor. By adopting this high
quality sensor plus special calculation and calibration, this thermometer is able to take accurate body temperature

Setting

Users can change the reading scale between Celsius and Fahrenheit, and change measurement mode between human body mode and object mode.
Measurement mode setting:
When the thermometer is on, it displays the current measurement mode ( fig.9.1). Press the “Mode” button to change measurement mode( fig.9.2).
Reading scale setting:
When the thermometer is on, it displays the current Reading scale. Press the “C/F” button to select the reading scale.
Notice:

1. The temperature under human body mode is obtained from dynamic compensation of environmental temp and forehead surface temp.
2. Object temperature mode is to tests the surface temperature of an object. The temperature gets from the forehead under this mode is merely the temperature of the forehead surface but not body temperature.

Measurement

10.1 Body temperature

• Press the measurement button to turn on the thermometer and it displays the boot screen (fig.10.1). After POST and two beeps, it will display the value of the last reading and be ready for measurement (fig.10.2).
• Make sure the thermometer is in underbody mode.
• Keep distance at 5cm to 8cm from the thermometer probe to the middle of the forehead (fig.10.3). Press the measurement button and then it gives a beep to indicate measurement is finished and value will be displayed (fig.10.4). If the measurement value exceeds the alarm value(Defaulted value is 38℃), it gives a beep. beep. beep as an indication.
• After measurement, if the thermometer is idle for 30 seconds, it will display OFF (fig.10.5) and gives a beep, and shut off automatically.

10.2 Object temperature

• Press the measurement button to turn on the thermometer (fig.10.6).

• Make sure the thermometer is under object mode.

• Keep vertical distance at 5cm to 8cm from object to measurement probe.
  Press the measurement button and then it gives a“beep” to indicate measurement is finished and value will be displayed (fig.10.7).

• After measurement, if the thermometer is idle for 30 seconds, it will display “OFF” (fig.10.8) and gives a “beep” and shut off automatically.
  

Notice:

1. The value under this mode is objected surface temperature instead of core temperature.
2. The default value of infrared emissivity is 0.95. The reading will deviate from the real temperature because of different emissivity. For example, the reading on stainless
   steel is obviously lower than the real temperature. BE CAUTIOUS FOR SCALDING.

10.3 Exceeding measurement range
Body mode:
When the measurement value is lower than 34.0ºC（93.2℉）, it displays Lo (fig.10.9) and gives“beep. beep.beep.beep”, with the color of backlight turning red.
When the measurement value is higher than 43.0 ºC（109.4℉）, it displays Hi (fig.10.10) and gives“beep. beep.beep.beep”, with the color of the backlight turning red.
Object mode:
When the measurement value is lower than 0ºC（32℉）, it displays Lo (fig.10.11) and gives “beep. beep.beep.beep”, with the color of backlight turning red.
When the measurement value is higher than 93ºC（199.4℉）, it displays Hi (fig.10.12) and gives“beep. beep.beep.beep”, with the color of the backlight turning red.
Notice:
When the surrounding temperature is lower than 15.0ºC（59℉） or higher than 40.0ºC（104℉）, it displays Err(fig.10.13) and gives “beep.beep.beep.beep”, with the color of backlight turning red.
Under this condition, it’s not allowed to use this thermometer, or accuracy is not assured.

Battery replacement

• Open the battery lid and take out the exhausted battery.
• Put into 2 AAA batteries and close up the battery lid. After the new battery is installed, the color of the backlight turns in the order of green, orange, and red, each of them
  flashing one time respectively, with a “beep” heard. If no beep is heard, please check if the positive and negative pole is correct (see fig.11.1).

Notice:

1. Take out the battery in case the thermometer is not used for a long time. Don’t put the battery to fire.
2. Dispose of battery according to local regulations.

Maintenance & tips

  Cleaning method for probe:
  1. Use the cotton stick or soft cloth with water or alcohol to wipe the casing.
  2. Use the cotton stick or soft cloth with alcohol to wipe the sensor surface or probe cavity gently. Don’t use a thermometer before alcohol is vaporized.

• Read this manual book thoroughly before use. Make sure the battery is well installed.
  It is not allowed to put the thermometer in any liquid or expose it to strong sunlight or extremely low temperature.

• A strong crash or hit to the product will cause its damage.

• Do not dismantle this thermometer by yourself.

• Keep the thermometer from children’s reach.

• Do not use the thermometer under circumstances of strong electromagnetic interference.

• The measurement results are probably fluctuating due to improper measurement ways.

LCD display “LO” or “HI”| 1. Breeze, water, sweating, cosmetics on the forehead may affect the measurement.
2. While if the testing environmental temp changes so enormously or if the thermometer is used directly from a high -temp object to a very low-temp one, the measurement difference will happen. The thermometer should be kept in a relatively stable environment for 10 minutes to get heat balance before starting a new measurement.
3. Ensure measurement distance is 5cm to 8cm.
No response when pressing the measurement button| 1. Take out and reassemble the battery.
No display or improper display| 1. Take out the battery and install the battery again.
Shut off right after switching on| 1. Check battery level or take out the battery and install the battery again.
