Taking an Oral Temperature
To accurately measure oral temperature with your iProven DTR-1835, ensure the thermometer tip is clean․ Place the thermometer tip under the tongue, towards the back of the mouth, on either the left or right side․ Close your mouth gently around the thermometer, avoiding biting down․
Hold the thermometer in place with your tongue, keeping your mouth closed throughout the measurement process․ This prevents inaccurate readings from external air․ The thermometer will beep when the reading is complete, typically within 60 seconds, though this can vary․
Carefully remove the thermometer from your mouth and read the temperature displayed on the LCD screen․ It’s recommended to wait at least 15-30 minutes after eating, drinking, or smoking before taking an oral temperature for the most accurate results․ Avoid using this method for infants or individuals unable to hold the thermometer securely․
Taking a Rectal Temperature
Important: Rectal temperatures are considered the most accurate, especially for infants and young children․ Apply a water-based lubricant to the thermometer tip before use․ Gently insert the thermometer tip no more than 1/2 to 1 inch into the rectum․
Hold the thermometer securely in place․ Do not release the thermometer until it beeps, indicating the reading is complete – typically within 60 seconds․ Avoid excessive force during insertion․
Carefully remove the thermometer and read the temperature displayed․ Rectal temperatures are generally 0․5°F (0․3°C) to 1°F (0․6°C) higher than oral temperatures․ This should be considered when interpreting the results․ Always clean and disinfect the thermometer thoroughly after rectal use, following the cleaning procedures outlined in this manual․ This method is not recommended for individuals with certain medical conditions; consult a healthcare professional if unsure․

Taking an Axillary (Armpit) Temperature
Procedure: Axillary temperature measurement is a non-invasive method, suitable for general screening, but generally less accurate than oral or rectal readings․ Ensure the armpit is dry before proceeding․ Place the thermometer tip high in the center of the armpit, ensuring good skin contact;
Instruct the individual to keep their arm firmly pressed against their side throughout the measurement process․ This ensures the thermometer remains securely positioned and maintains consistent contact with the skin․ Hold the thermometer in place until it beeps, signaling completion – usually around 60 seconds․
Remove the thermometer and record the temperature․ Axillary temperatures are typically 0․5°F (0․3°C) to 1°F (0․6°C) lower than oral temperatures․ Add this difference when interpreting the reading․ Clean the thermometer tip after each use․ This method is best for initial screening and may require confirmation with another method for accurate diagnosis․
Reading the Temperature Display
Display Features: The iProven DTR-1835 features a clear, easy-to-read LCD display․ After taking a measurement, the display will show the current body temperature in Fahrenheit (°F) or Celsius (°C) – the unit can be changed in the settings․ A decimal point separates whole numbers from tenths of a degree, providing precise readings․
Symbols & Indicators: Pay attention to accompanying symbols․ A low battery indicator will appear when the batteries need replacing, ensuring accurate measurements․ A “PROBE” error indicates improper probe placement or a faulty sensor․ The display also features a fever indicator; a flashing or continuously lit fever symbol alerts you to an elevated temperature․
Memory Recall: The display will also show “M” when recalling a previously stored temperature from memory․ Ensure adequate lighting when reading the display for optimal clarity․ Familiarize yourself with these indicators for effective temperature monitoring and interpretation․
Understanding Fever Indicators and Alerts
Fever Detection: The iProven DTR-1835 is equipped with a sophisticated fever detection system․ A temperature of 100․4°F (38°C) or higher is generally considered a fever․ The thermometer visually alerts you to elevated temperatures through distinct indicators on the LCD screen․
Visual & Auditory Alerts: The fever alert typically manifests as a flashing or continuously illuminated fever symbol․ Some models may also include an audible beep to draw your attention․ The intensity of the alert doesn’t necessarily correlate with the severity of the fever; always consider the patient’s overall condition․
Interpreting Alerts: A consistent fever warrants medical attention․ Monitor the temperature regularly and consult a healthcare professional for guidance․ Remember that fever indicators are a tool for detection, not diagnosis․ Always prioritize professional medical advice when dealing with illness․
