The “ L ” means that the thermometer is at its lowest point and ready to take your temperature . It does not mean the battery is low.
Both laboratory and clinical studies show that there is no significant difference in the average accuracy of the two types of thermometers, however there is a greater fluctuation of readings of temperature when using electronic thermometers.
Some digital thermometers do not require any adjustment of a screw or nut. You simply need to locate the reset button. When the freezing point or boiling point of water is achieved, push or hold the button and that’s it.
A digital thermistor thermometer provides an excitation voltage or current to the thermistor. The excitation is converted to a voltage signal by the thermistor and the thermometer then converts the measured voltage to temperature.
My digital thermometer does not beep or register a number, why? Most likely, it has either run out of power or is broken. Try recharging/replacing the battery, or replacing the thermometer .
The advantages of digital thermometers are that they are inexpensive, easy to read, require very little maintenance and give an accurate reading. The disadvantage is that they get damaged easily if dropped and the battery powering them eventually runs out.
A digital thermometer should always return accurate readings. Whether you use it for cooking, for measuring body temperature, atmospheric temperature, or any other relevant use, a thermometer should always be made to provide the correct temperature. From time to time, digital thermometers will require recalibrating.
Proper Ways to Use a Thermometer Gun Set the Reading to Fahrenheit or Celsius. You can move the toggle switch easily to change your measurement to Fahrenheit or Celsius. Set the Measurement Unit. Turn on the Laser Gun. Aim the Gun. Get Close. Pull the Trigger.
Insert the thermometer stem at least an inch deep in the ice water without letting the stem touch the glass. Wait for the thermometer to register; this usually takes a minute or less. The thermometer is accurate if it registers 32° F or 0° C. (My three thermometers are within 1 degree of accuracy at this end.)
To use a digital thermometer : Clean the tip with cold water and soap, then rinse it. Turn the thermometer on. Put the tip under your tongue, towards the back of your mouth. Close your lips around the thermometer . Wait until it beeps or flashes. Check the temperature on the display.
Reset the thermometer by pressing reset button. Place the thermometer under the tongue. Close mouth around thermometer . Leave in place until you hear the beep (usually one minute or less)
Rectal thermometers, which go into your rear end, are the most accurate, but they can be uncomfortable. Armpit , ear , and forehead thermometers aren’t as accurate. Most doctors think an oral thermometer, which you hold under your tongue, is best. Don’t use an old glass thermometer.
Oral/Rectal/Axillary Digital Thermometers 5 F to 1.0 F (. 3 C to . 6 C) degrees below rectal, ear, and temporal readings. Add .
The normal temperature range on the forehead is approximately between 35.4 °C and 37.4 °C.
