Does this model ever require calibration?

Yes, it is police grade accurate and they say calibrate it 6 months to a year. I'm going to do it after a year and I used it a lot. This one is awesome, and very accurate with BAC and time until sober

Yes, the BACtrack Mobile Smartphone Breathalyzer needs to be calibrated every 12 months.

Hi Jim, no it does not, as it comes calibrated. We can ship one out tomorrow if you decide you need one of these. Thanks, Ron

It is factory calibrated at the time of manufacture. If you need current calibration that must be done when purchased. Some retailers offer calibration for an extra fee or you can send it out to your local calibration shop.

No special calibration is needed. As far as what tools to use, there should be instructions with your kit about the installation process.

I never calibrated and just started using it. I took several packages to the post office and everything checked out perfectly. They explain how to calibrate it in the manual.

No you don't. My understanding is that it is supposed to have an internal mechanism to calibrate.

In the User Manual, there are no instructions for calibrating this particular model (ME-5KG), so I'm fairly certain calibration is not available for this scale.

It appears that calibration is not required on all of the scales. However, even trying to calibrate the scale still didn't work for me. I did like the fact that it had a bowl on top and the proposed functionality but I wasn't able to get that far.

Mine was pretty well calibrated (within .02g for the 500g weight). It really depends on how accurate you want it to be. It is not "self calibrating". A set of calibration weights will help keep your scale as accurate as it can be.

Fortunately there is no calibration needed. It works right out of the box. There is no "on" button, the display and pressure sensor are simply activated by pressing the device onto a valve. Works for my car and my bike tires, too. Display turns off automatically after 15 seconds or so. Can't recall the exact time.

Yes, it does have the adjustable calibration. It is almost identical to the TM40 except it has two back lighting options on the display (bright/brighter) AND the angle of the kickstand on the back kicks out instead of flipping out to the side.

No it's not pre-calibrated however photography and videography is specifically what I bought this monitor for. Monitors go out of calibration and knowing that ahead of time, I bought the Datacolor Spyder4Elite S4EL100 Colorimeter for Display Calibration a few years back. I calibrate it every 3 months.

I agree with DBroncos spending the dough on getting this model calibrated is a joke. If you're scared you may not know how to calibrate properly just copy settings from this thread. http://www.avsforum.com/avs-vb/showthread.php?t=1019763

It does not require calibration, but it sometimes under-weighs by .1 ounce. I bought a set of 1 oz and 2 oz weights and test it occasionally, especially when I get a reading that is exactly 1, 2, or 3 ounces.

I think so but I'm uncertain. It wouldn't surprise me though if it doesn't work properly. It's probably not calibrated to work with it specifically.

The only calibration I have seen happens during each power-on. The directions ask for a vial of clear pool water and it self calibrates.

It comes with maybe a ketchup packet worth of calibration solution which will calibrate initially. You can go about a month without calibrating. It falls off a point or 2 by then.

Yes because the device calibrates it to match a standard calibration. So what you see is what other's see when they have also calibrated. Therefore it will calibrate them all to the same standard.
