How to use the Marque Verte Digifront Compact thermometer?

Question

Accepted Answer

The Marque Verte Digifront Compact thermometer is a digital infrared forehead thermometer that measures temperature by scanning the area of the forehead above the eyebrows. Here’s how to use it correctly:

Preparation
Before starting, ensure that you and the device have been in a room with a stable temperature for at least 30 minutes. Avoid taking the temperature during or immediately after breastfeeding a baby. The patient should not have drunk, eaten, or exercised a few minutes prior.

Turning on
Press the “ON/OFF” button. The screen lights up and displays all segments for 2 seconds. The last recorded measurement is then automatically displayed for 2 seconds. When the °C or °F symbol blinks accompanied by a beep, the device is ready to measure.

Taking the temperature

First, clean the forehead by removing hair, sweat, or dirt to improve accuracy
Gently place the probe about 1 cm above the center of the eyebrow (skin contact required)
Press the “START” button once and release
Slowly move the thermometer from the center of the eyebrow to the temple for 3 seconds
A long beep sounds after 3 seconds, indicating that the measurement is complete
If you moved too slowly, start again by moving the probe faster

Reading the result
The temperature is displayed on the LCD screen. A green backlight means the temperature is below 37.5 °C. A red backlight accompanied by 10 short beeps indicates that the temperature is equal to or above 37.5 °C, indicating a risk of fever. Always take the temperature at the same spot on the forehead, as readings can vary depending on the measurement location.

Case of abnormally low measurement
If the result seems abnormally low or does not match the patient's condition, repeat the measurement 3 times at the same spot and retain the highest temperature. This is particularly important for children under 3 years old or cases where the patient has just learned to use the thermometer.

Cleaning and maintenance
After each use, clean the probe with a pad or cloth soaked in 70% alcohol. Wait at least 15 minutes before measuring the temperature of another person. Never immerse the device in water and do not clean it with abrasive products. The screen automatically turns off about 1 minute after the measurement to save battery. Store the device in a dry place.

Features and limitations
The accuracy is ±0.2 °C in the range of 36.0 to 39.0 °C. The device operates with a CR2032 battery and can perform about 2000 measurements. Do not use the thermometer in very humid environments. Keep in mind that the forehead temperature can naturally be 0.2 to 1 °C lower than the baseline body temperature, like any skin measurement. Inform your doctor of the thermometer used and the area measured.
