INTRODUCTION

The DT-29 Infrared Thermometer has been developed using the latest infrared technology. This technology allows the body temperature to be taken at a distance of about 3cm-5cm from the forehead. Delivering precise, instantaneous readings without skin contact, the DT-29 is currently the most suitable thermometer for no-risk temperature measurement. It has been demonstrated that this method of temperature measurement is more precise than tympanic thermometry and better tolerated than rectal thermometry (1). However, as with other types of thermometers, it is essential to use the DT-29 properly in order to obtain reliable and stable results. You are therefore advised to read this instruction manual and observe the safety precautions carefully before use.

PRECAUTIONS BEFORE USE

The DT-29 Infrared Thermometer is pre-set at the factory.
It is not necessary to calibrate the device before using it.
To ensure reliable and stable results, the instrument will advise you each time there is a significant environmental ambient temperature change. Allow the DT-29 to acclimate to the new ambient temperature for fifteen to twenty minutes. It is important to allow for an approximately one-minute interval between two measurements for the most accurate readings.

OPERATING PRINCIPLE

All objects, solid, liquid or gas, emit energy by radiation. The intensity of this energy depends on the temperature of the object. The DT-29 Infrared Thermometer is able to measure the temperature of a person by the heat energy the person emits. This measurement can be taken by an external temperature probe on the device that permanently analyzes and registers the ambient temperature. As the clinician holds the instrument near the body and activates the radiation sensor, the measurement is taken instantly by detection of the forehead heat. Body heat can therefore be measured without any interference from the heat of the surrounding environment.

THE DIFFERENT METHODS OF TEMPERATURE MEASUREMENT
Core temperature
Core temperature is the most precise measurement and involves measuring the temperature in the pulmonary artery by means of a catheter equipped with a thermal probe that can read the temperature in situ. The same method is employed for probes measuring the esophageal temperature. However, such invasive temperature measurement methods require specific equipment and expertise and are not practical for everyday use.
Rectal thermometry
Rectal temperature adjusts slowly in comparison to the change in body internal temperature. It has been demonstrated that this temperature remains raised long after the internal temperature of the patient has started to drop and vice versa.

Oral thermometry
Oral temperature is easily influenced by recent ingestion of food or drinks and by breathing through the mouth. To measure oral temperature, the mouth must remain closed and the tongue lowered for three to four minutes, a difficult task for young children to accomplish.
Axillary (armpit) temperature
Although it may be easy to measure axillary temperature, it has been proven that it does not provide an accurate measurement of the patient’s internal temperature. To make this type of temperature, the thermometer must be wedged tightly over the axillary artery. Despite the low sensitivity and relative inaccuracy of axillary temperature in detecting fever, this method is recommended by The American Academy of Pediatrics as a screening test for fever in newborns.
Tympanic thermometry
In order to obtain a precise temperature reading, good command of the measurement technique is required. The thermometer probe must be placed as close as possible to the warmest part of the external ear canal. An incorrectly placed probe could lead to a false temperature reading.

NORMAL TEMPERATURES ACCORDING TO MEASUREMENT METHOD

The temperature of the human body varies throughout the day. It can also be influenced by numerous external factors: age, sex, type and thickness of skin, hormonal supplements, and others.
The DT-29 Infrared Thermometer has been designed to produce an instant forehead temperature representing core temperature reading without touching the skin. Since the body temperature is permanent and regular on the forehead, it allows precise measurement of the temperature. The efficiency, speed, and comfort of taking a temperature from this area make it ideal compared with other temperature measurements methods.
NORMAL TEMPERATURES ACCORDING TO AGE

PRACTICAL CONSIDERATIONS WHEN TAKING A TEMPERATURE
– In order to ensure that precise and accurate temperature measurements are obtained, it is essential that each user has received adequate information on and training in the temperature measurement technique when using this device.
– It is essential to remember that although procedures such as taking a patient’s temperature may be simple they must not be trivialized.
– Temperature should be taken in a neutral context. The patient must not have undertaken vigorous physical activity prior to taking his/her temperature and the room temperature must be moderate.
– Be aware of physiological variations in temperature when evaluating the results: temperature increases by 1.0F° between 6 am and 3 pm. Women have a temperature that is higher, on average, by around .5F°. Their temperature also varies in accordance with their menstrual cycle. It rises by 1.0F° in the second half of the cycle and at the early stages of pregnancy.
– When sitting, the temperature is lower by about 0.5 to 0.8F° than when standing.

HOW TO TAKE A TEMPERATURE

Aim at the forehead, over the right eyebrow, from a distance of about 2 inches, press the measurement button and the temperature is instantly displayed. The reliability of the measurement cannot be guaranteed if the temperature is measured over another part of the body (e.g., arm, torso…).

ADDITIONAL CONSIDERATIONS BEFORE USE
Please observe the following before taking any temperature measurement to ensure a stable and reliable result:
– Push back the hair from the forehead
– Wipe away any perspiration from the forehead
– Avoid any drafts (e.g. from the nasal cannula, air conditioning…)
– Allow a 1-minute interval between two measurements.
– Each time there is a significant change in the ambient temperature due to a change in the environment, let the DT-29 acclimate to this new ambient temperature for at least 15 minutes before using it.

THE SCREEN DISPLAYS A BODY TEMPERATURE LESS THAN 89.6°F ( 32°C) To take a body temperature the function must be on Body mode. If you’re on Surface Temp mode, the 89.6°F (32°C) temperature displayed is the external skin temperature.
THE SCREEN DISPLAYS THE MESSAGE: HI
When using the DT-29 Infrared Thermometer the message HI can appear on the screen.
The analysis is above the measurement range selected, either greater than 109°F (42.9°C) in Body Mode or greater than 140°F (60°C) in Surface Temp Mode.
THE SCREEN DISPLAYS THE MESSAGE: LO
When using the DT-29 Infrared Thermometer, the message Lo can appear on the screen.
The temperature measured is under the measuring range selected, either less than 90°F (32°C) in Body Mode or less than 32°F (0°C) in Surface Temp Mode. The following messages appear in various cases:

there is no obstruction prior to taking a temperature.
Temperature hampered by an air current (A/C).| Make sure there is no air current as this could interfere with the measuring system.
Temperature readings were too close together, the thermometer did not have the opportunity to re-set.| Pause for 3-5 seconds minimum between two readings — 15 seconds pause is advised.
The measuring distance is too far.| Please maintain the measuring distance between 3 and 5 cm (1. 2 in. —2.0 in.).
