How To Change Braun Thermoscan From F To C

[Renita Lukins]

To change the temperature reading on a Braun ThermoScan from Celsius to Fahrenheit, you need to first ensure the thermometer is off. Then, press and hold down the power button until the display shows either F (Fahrenheit) or C (Celsius). Release the power button when the desired unit is displayed.

Braun ThermoScan measures the infrared heat generated by the eardrum and surrounding tissue. Because the eardrum shares blood supply with the temperature control centre in the brain, measurement with Braun ThermoScan accurately reflects changes in core body temperature.

Care and cleaning
The probe tip is the most delicate part of the thermometer.
It must be clean and intact to ensure accurate readings.
If the thermometer is ever accidentally used without a lens filter, clean the probe tip as follows: Very gently wipe the surface with a cotton swab or soft cloth moistened with alcohol. After the alcohol has completely dried out, you can put a new lens filter on and take a temperature measurement.

If the probe tip is damaged, please contact the local service center.
Use a soft, dry cloth to clean the thermometer display and exterior. Do not use abrasive cleaners. Never submerge this thermometer in water or any other liquid. Store thermometer and lens filters in a dry location free from dust and contamination and away from direct sunlight.

We have a Braun Thermoscan infra-red (IR) thermometer that has been working perfectly for about five years. It started complaining about low batteries and shutting off, despite me replacing with new batteries that I checked had plenty of charge.

When I opened it, I discovered that the batteries connect to the circuit board via simple metal clip contacts, and that the contacts had some corrosion on them, which was preventing power from getting to the board, hence why it was complaining of low batteries.

This image above also shows the contact points on the circuit board for the battery connection. This is where some corrosion had formed, and I could remove it simply by scraping lightly with a small screwdriver (the corner of a scourer would also have worked).

Same problem here with the bent contacts for the battery not making contact. Love this thermometer but being an electronics engineer and looking at the circuit board and overall design of how it powers up I agree with the comment that the design is poor for expecting a long term product life.

Our thermoscan had been working well, but I am not 100% sure if it is me or just in daylight (I tried using in a dark room). But the light stays on until the moment it gets a reading and then the backlight turns off immediately. Bit of a pain as that is when you want the backlight on! Anyone had similair problem? Also I put cheap coles batteries into it, but they are brand new, so still should be fine?

Hi Kevin, im having the same battery problem as yours in the same model. Trying to follow your fix, trying my best to open it, but once the screw is out, i dont know how to open it further. Im stuck. Can u pls help. Would love for u to put up a utube video so its easily follow able.

Wow, thanks Kevin, I followed your very helpful instructions and it solved the problem I was having with our 10-year-old Braun thermometer. Your instructions are quite clear and, in my opinion, better than following a YouTube video.

Thank you! You have been great help. Was kind of sad when I just could not get the Thermoscan 6022 to start up after changing batteries. Then I stumbled upon your article, followed your instructions and now it is working again.

Thanks Kevin as I followed your advice and my 6020 seems to be working again. It was saying lo then hi. I changed the batteries and then just got a constant error message or a reading of 41c! I was just about to throw it out when I found your advice. Followed it and it is working and giving realistic reads again. Thanks so much.

If soldering is not possible, then perhaps you could very carefully bend the clips (only a small amount) so that they rest on a slightly different part of the copper pad. Alternatively, kitchen foil could be used to increase the surface area of the clip.

Thank you so much for sharing this. I bought my thermometer in the US (I live in Korea) about 5 years ago and it stopped turning on recently. I thought I was going to have to shell out $100 for a new one here but I found your fix and it worked like a charm. Definitely good to have during this flu/corona virus season!

My approach would be to lightly tin what remains of the tab, and tin some multi-core wire. Then solder the tinned threads to the pad and snip them to leave fresh points of contact. You have to take a lot of care with damaged pads, not to rip them up.

The little red pin is essentially a push-button that should push in easily when the ear protector is attached. If yours is not pressing in, then it must be obstructed somehow. I would first try wiggling it carefully, to see if it could be freed up (tweezers might help).

My Thermoscan was coming up with the POS error all the time and when opened up realised the battery connectors were corroded. Scraped all the corrosion off and tried again but still kept giving the error.

The Braun ThermoScan 3 IRT 3030 is a digital ear thermometer that measures the temperature in a flash. Suitable for the whole family, but the quick measurement time makes it particularly suitable for taking the temperature of children who do not want to sit still. The thermometer's display shows temperature and has a sound signal that indicates fever during the measurement.
The Braun IRT 3030 has the unique ExacTemp technology with a control system that confirms that you have placed the thermometer in the correct position in the ear to ensure a correct measurement.
The thermometer is supplied with a 3 V lithium cell battery (type 2032). Insert a new battery when the low battery symbol appears on the display.
Digital ear thermometer
Measures the temperature in a flash.
Memory function for eight measurements.
For the whole family
Battery and 21 lens filters included.

Use hygienic disposable lens filters to reduce the risk of bacterial transmission. 21 disposable filters included. New disposable covers are sold separately, see Braun Thermoscan Lens Cover
Read the instructions for use included in the packaging carefully before use. Before using the thermometer, remove the small sticker with numbers on the display. The thermometer must be at stable ambient temperature (room temperature) for 30 minutes before use.
Before using the thermometer, make sure the ear is free of obstructions or earwax build-up. Change to a new disposable filter after each use to ensure hygiene. (The thermometer cannot be used without a disposable filter.) The filter is needed to protect the measurement sensor so that it can take accurate readings.
1. Switch on the thermometer by pressing the start button. A flashing lens filter symbol is displayed if no lens filter is attached. The temperature can only be taken if the lens filter is attached to the probe (the part you stick into the ear). The thermometer is ready to use when two beeps are heard and the non-flashing ear icon is displayed.
2. Insert the probe into the ear canal so that the ear canal closes tightly around it and then press the start button. One (1) signal indicates normal temperature. Two (2) beeps will sound if the reading is equal to or greater than 37.5C. Four (4) beeps will sound if the reading is equal to or greater than 38.6C. The result is shown on the display.
3. Carefully pull off the disposable filter and discard it.
The Braun ThermoScan switches off automatically after 60 seconds of inactivity. You can also turn off the thermometer manually by pressing the start button and holding it for more than 5 seconds.
The thermometer can display temperature in both Celsius and Fahrenheit. To change the temperature scale, do the following:
Check that the thermometer is switched off. Press the >>start>> button. Continue to hold the >>start>> button. After about 3 seconds, the display starts switching between the temperature scales (C and F). Release the start button when the desired temperature scale is displayed. The thermometer is adjusted to the new temperature scale.
About body temperature
Normal body temperature is a range, and varies depending on where you measure, and it tends to decrease with age. It also varies from person to person and fluctuates during the course of the day. Therefore, it is important to establish your normal temperature range.

A thermometer which you can mute may also be ideal, particularly if the child is trying to sleep while you take their temperature. Lastly, the temperature level upon reaching a fever will vary by age, and some thermometers can actually be adjusted to take account of this. This is why the Braun ThemoScan 7 was ranked as the best thermometer for kids in our tests. It offers three age settings, from 0-3 months, 3-36 months and 36 months +, so it can warn you when a fever is reached at a younger age via its red, amber and green backlight. While it is an in-ear thermometer, we like that it comes with a pre-warmed tip to limit discomfort.

However, if you are buying an all-around thermometer for family use, investing in a thermometer most suitable for a child is the sensible option. Otherwise, it comes down to personal preference and how you find it easiest to have your temperature taken. If you dislike having an oral thermometer placed under your tongue, where it needs to be kept in place for an accurate reading, you may prefer to opt for a digital ear thermometer.

No medicine cabinet is complete without one of the best thermostats. They are a must-have device in our homes and essential for young families, as babies and young children cannot always tell how they feel. However, whether you have children or not, thermostats are especially important for checking for bugs and viruses, as they will accurately measure whether your temperature is raised and if there is any need for medical intervention.
