|
Why is my measurement too low or high? |
Ans: |
You may check by following items:
| Ear Canal: |
Earwax might block the infrared measure accuracy. |
| Probe Cover: |
The most popular situation is the probe stuck with earwax that blocked infrared transmission and lower the measurement. If you bought a probe cover model, we recommend user to change probe cover each time to avoid cross contamination. |
| Note: |
If you bought a probe cover model, the probe cover may break and affect the accuracy after using for several times or receive external hit. We recommend user to check probe cover's integrity before every measurement. If the probe cover is broken, please change a new one. |
| Lens: |
If you bought a probe cover model, the most common situation is user measure without installing probe cover. The probe lens is stuck with earwax and lower the measurement. If the lens is dirty, please follow the manual's instruction to clean lens with cotton swab. |
| Note: |
User hit the thermometer carelessly might cause the probe lens damage. Please return full package to retailer for service if there is damage. |
|
|
|
May I reuse the probe cover? |
| Ans: |
If you bought a probe cover model, in order to avoid cross contamination, we recommend user to change probe cover after each measurement. Also, check the probe cover is in good shape and the ear canal is clear without earwax.
|
 |
|
Why do I get different temperature for continuous measurement? |
| Ans: |
The thermometer needs to adapt to ambient temperature. The rapid temperature change may also cause the inaccurate measurement. We recommend user to place thermometer indoor for 20 minutes to adapt to temperature and get the correct measurement.
|
|
How to open the battery cover to replace battery? |
| Ans: |
Insert a pointed object into the pick hole on battery cover.
Meanwhile, use thumb to push battery cover out and change battery.
(Battery installation picture take TH809 for example. For other models, please refer to the user's manual.)
|
|
How do I have my ear thermometer repaired? |
| Ans: |
Please send the complete device to the nearest retailer for service.
|
|
I lost my ear thermometer's manual. |
| Ans: |
Don't worry. RADIANT INNOVATION provides consumer online thermometer manuals to download.
|
|
My temperature measured in the right ear is different from that measured in left ear? |
| Ans: |
The ear canal of both ears is not totally the same. Some people can get same temperature but most people could get 0.5 ~ 1.0 ° C different temperatures. It is recommended that you measure 3 times with the same ear. If the 3 measurements are different, select the highest temperature.
|
|
Does forehead mode need to touch body? |
| Ans: |
In forehead mode, please measure close to temples about 0.5 centimeter distance. Although the thermometer does not touch body, please also follow the instruction for clean and storage to keep accuracy.
|
|
What is the normal body temperature? |
| Ans: |
A normal range for body temperature is 35.8°C ~ 38.0°C (96.4°F ~ 100.4°F). Each person has different temperature, please contact qualified doctor for details.
Here are the normal body temperatures for reference:
| Ear Temperature: |
35.7°C ~ 37.5°C |
| Rectal temperature: |
35.7°C ~ 37.5°C |
| Oral temperature: |
35.5°C ~ 37.5°C |
| Armpit temperature: |

The baby's ear canal is too small to insert the probe. How do I measure the temperature? |
| Ans: |
Don't worry. You can pull the baby's ear straight back to make sure the ear canal is straight. Make the probe lens face to the ear drum and get the temperature.
|
Note:
For children under 2 years old, pull the ear straight back.
For adults and children over 2 years old, pull the ear up and back.

|
Does ear thermometer need to maintain regularly? |
|
| Ans: |
Ear thermometer is a health care product that needs maintenance, you could use soft cloth to wipe the appearance. Never use benzene for cleaning and never submerge thermometer into water or any liquids. Probe lens is the most delicate part of thermometer, please use cotton swab with alcohol (70%) to wipe it.
|
 |
|
Can I measure without probe cover? |
| Ans: |
If you bought a probe cover model, we recommend user to install probe cover before measurement base on hygienic principal. A thermometer measurement without probe cover might cause 1° C inaccuracy.
|
|
Is the thermometer waterproof? |
 |
| Ans: |
Be careful! The thermometer is not waterproof. Please do not submerge in any liquid and avoid the direct sunlight over 10°C to 40°C (50°F to 104°F) environment.
|
|
How long do I have to change thermometer's battery? |
| Ans: |
RADIANT INNOVATION ear thermometer uses a lithium battery (CR2032). The battery life depends on the frequency you use. Please change a new battery when the LCD battery icon flashing.
|
|
Does ear thermometer radiate infrared? |
| Ans: |
The ear thermometer receives the ear drum's infrared and switch to body temperature; therefore, it does not radiate infrared.
|
|
Can I measure temperature when I have tympanitis or a wound in my ear? |
| Ans: |
To avoid the ear disease worsen, please do not use the thermometer.
|
|
Do I have to lie down while I use ear thermometer? |
| Ans: |
You don't need to lie down. You may use at any place, any time, even when you are boarding.

Know -How of Infrared Thermometer |
|
| |
|
How does the infrared thermometer work? |
| Ans: |
Each object radiates infrared capacity. A hot object radiates more infrared than a cold object does. The infrared thermometer use optical device to collect infrared capacity and transfer into electrical signal by the detector.
|
|
How long does infrared thermometer response? |
| Ans: |
The infrared thermometer's response time is faster than common thermometer about 0.5 seconds.
|
|
What is the maximum distance for measurement? |
| Ans: |
The distance depends on the optical device inside the thermometer. Use Distance/ Size and target's diameter to decide maximum distance. According to the atmosphere, most infrared thermometer's maximum measuring distance is about 100 foots.
|
|
What is an optical spectrum? Why is it important? |
| Ans: |
The infrared spectrum is about 0.7 to 1000?m. The spectrum of infrared thermometer we use is about 8-20?m. This range is most stable and less affected by CO2 and H2O for the best accuracy.
|
|
What is Emissivity? |
| Ans: |
Emissivity is the ability an object radiates or absorbs. An ideal Emissivity is "1" that radiates 100%. 0.8 Emissivity means to absorb 80% and radiate 20%. Emissivity variations affected by temperature and spectrum response. A shinning metal is hard for infrared thermometer to measure temperature due to emissivity.
|
|
How to confirm an object's Emissivity? |
| Ans: |
1. |
First, use exterior thermocouple to measure the object's exterior temperature and then use infrared thermometer to measure the face to adjust the emissivity. Try until thermocouple and infrared thermometer get the same reading. |
2.
|
For a 500°F (260°C) object, place the adhesive tape on the object to reach hot balance. Use a 0.95 Emissivity infrared thermometer to measure and record the temperature. Next, measure the exterior temperature and adjust emissivity until the same temperature as the tape.
|
|
What is the measuring range of infrared thermometer? |
| Ans: |
Infrared thermometer could measure an object in the Distance: Spot equal to its diameter. In this range, infrared thermometer could get the most accurate temperature; over the range might cause inaccuracy.
