Measuring in object mode
1. Follow steps 1-2 above, then aim the thermometer at the center of the object you want to measure with a distance of no more than 5
cm. Press the START button 4. After 3 seconds a long beep will verify the completion of measurement.
2. Read the recorded temperature from the LCD display.
NOTE:
• Patients and thermometer should stay in similar room conditions for at least 30 minutes.
• Don’t take a measurement while or immediately after nursing a baby.
• Don’t use the thermometer in high humidity environments.
• Patients should not drink, eat or exercise before/while taking the measurement.
• Don’t move the measurement device from the measuring area before hearing the termination beep.
• 10 short beeps and a red LCD backlight alert the patient that he/ she may have a temperature equal to or higher than 37.5 °C.
• Always take the temperature in the same location, since temperature readings may vary according to locations.
• Doctors recommend rectal measurement for newborn infants within the first 6 months, as all other measuring methods might lead to
ambiguous results. If using a noncontact thermometer on those infants, we always recommend verifying the readings with a rectal
measurement.
• In the following situations it is recommended that three temperatures are taken with the highest one taken as the reading:
1. Children under three years of age with a compromised immune system and for whom the presence or absence of fever is critical.
2. When the user is learning how to use the thermometer for the first time until he/she has familiarized himself/herself with
the device and obtains consistent readings.
3. If the measurement is surprisingly low.
• Readings from different measuring sites should not be compared as the normal body temperature varies by measuring site
and time of day, being highest in the evening and lowest about one hour before waking up.
Normal body temperature ranges:
– Axillar: 34.7 – 37.3 °C / 94.5 – 99.1 °F
– Oral: 35.5 – 37.5 °C / 95.9 – 99.5 °F
– Rectal: 36.6 – 38.0 °C / 97.9 – 100.4 °F
– Microlife NC 150 BT: 35.4 – 37.4 °C / 95.7 – 99.3 °F
