for these devices to read body temp from a forehead reading involves 2 temperatures, the room temp and the forehead reading , it must calculate the offset according to room temp. forehead readings up to 96 is normal , above would indicate a fever , unless the room temp approaching 90 and above , the closer the room temp to a normal body temp , the closer the actual reading will be of the actual body temp.i am looking for one that works this way , this appears to be not a smart version , but a basic one and setting the offset would require resetting offset for changing room temperatures constantly , unless your room is under constant temperature control you are taking your reading in.
What you describe is an infrared thermometer with built-in ambient sensors to detect and compensate for the ambient temperature. This Extech IR200 does not have these sensors. In our experience with the IR200, after being calibrated in reference to an oral thermometer, it is accurate to within specification. In general, the best practice is to leave the thermometer in the testing location for at least 15 minutes prior to use so it can acclimate. You should also only use these thermometers indoors, away from doors and windows, and make sure that subjects have not been in direct sunlight for long periods.

If you need to calibrate the IR thermometer, then yes you'll need a reference thermometer with good accuracy. The best practice is to use an oral thermometer like in this video - oral thermometers are much cheaper than IR thermometers and can be bought for just a few dollars.
I didn't calibrate it earlier when i was using..I haven't had fever then..so I couldn't figure out whts wrong with the reading. Now that I caught fever when i used it, it still showed me normal temperature as 98.1F and while i took conventional thermometer reading it showed 100°F and I panicked instantly..now I've callibrated the offset value to +2..but could you please confirm if it'll continue showing the accurate value now on or should it requires calibration everytime.if everytime then its of no use for me..i would switch to my old conventional thermometer.
You should not have to calibrate the IR thermometer every time you use it. It also should not matter what your temperature was when you calibrated the IR thermometer as long as you did the calibration properly. The way you describe it sounds correct so you should be good from now on. If you are concerned, test yourself again with both thermometers and compare the readings - they should be the same.
what many people forget is forehead and underarm temps read 1 degree less than actual body temp. In healthcare, we know to add a degree when taking an axillary (underarm) temp so same should go for the forehead. If you want a true core temperature..... gotta go rectal!
You're 100% correct, that's why this video explains the proper calibration and compensation for that difference using an oral thermometer. Rectal is probably the most accurate way to do this but good luck getting people on board with that!
This could possibly be for factory calibration. There is no mention of a fifth function in the product manual - check out page 4 under "Body Temperature Mode settings" and it only lists the 4 functions discussed in this video: res.cloudinary.com/iwh/image/upload/q_auto,g_center/assets/1/26/Extech_IR200_User_Manual.pdf
Taken from the IR200 user manual on page 4: If the temperature goes above 109°F or 43°C, Hi will appear in the display. If the temperature goes below 86°F or 30°C, Lo will appear in the display.

So, I need another thermometer to set my thermometer?!

What is the fifth setting u don't go over it f5 pop up CAL and u can turn it on and off what is it?

Hello team, what does HI means ? It appears on the screen when i cannot get the température ?
Taken from the IR200 user manual on page 4:
