- Before using the thermometer for the first time, please disinfect the probe.
- To switch on, press the ON / OFF button next to display; a short beep will sound, indicating that the thermometer is operational.
- At the same time the thermometer runs a self-check test, during which the symbol “ “ appears on the LCD.
- When the letters “Lo” and a flashing “°C” or “°F” show on the display, the thermometer is ready for use.
- If the ambient temperature is below 32 °C or 89.6 °F, then “Lo °C” or “Lo °F“ will appear on the LCD. If it is more than 42,9 °C or 109.2 °F, then “Hi °C” or “Hi °F“ will appear on the LCD.
- During the measurement process, the current temperature is displayed continuously and the “°C” or “°F” symbol flashes. The measurement is completed when a constant temperature value has been reached. The temperature value is considered constant when the temperature rises less than 0.1 °C within 4 seconds. As soon as the constant temperature value is reached, a beep will sound four times, and the “°C” or “°F” symbol will stop flashing.
- The highest temperature measured appears on the LCD.
- When the measurement is completed, please switch the thermometer off by pressing the « ON / OFF » button.
METHODS OF MEASURING TEMPERATURE:
It is important to remember that the body temperature reading depends on the site where it is measured. For this reason, the measurement site must always be specified in order to ensure that a correct temperature reading is recorded.
In the rectum (rectal):
This is the most accurate method from a medical point of view, because it comes closest to the core body temperature. The thermometer tip is inserted carefully into the rectum for a maximum of 2 cm. The usual measuring time is approximately 9 to 11 seconds.
In the mouth (oral):
There are different heat zones in the mouth. As a general rule, the oral temperature is 0.3 °C to 0.8 °C lower than the rectal temperature. To ensure that reading is as accurate as possible, place the thermometer tip to the left or right of the root of the tongue. The thermometer tip must have constant contact with the tissue during the reading and be placed under the tongue in one of the two heat pockets at the back, keep the mouth closed during the reading and breathe evenly through the nose. Do not eat or drink anything before the measurement. The usual measuring time is approximately 15 to 19 seconds.
Under the armpit (axillary):
Placing the thermometer in the armpit provides a measurement of surface temperature that can fluctuate by around 0.5 °C to 1.5 °C from rectal temperature readings in adults. The usual measuring time for this method is approximately 23 to 29 seconds. It should be noted, however, that an exact reading cannot be obtained if, for example, the armpits have been allowed to cool. If this is the case, we recommend extending the measuring time by around 5 minutes in order to obtain the most precise possible reading that corresponds as closely as possible to the core body temperature.
Note: We strongly recommend the rectal method as the most accurate method for identifying the basal temperature, We recommend to extend the measuring time by 3 minutes after the beep.
