Is there a need for Calibration? How do you calibrate it if so?

I don't think so. I used it on my tires and it worked fine as it should without calibration. My tires are supposed to be 32 psi and that's what I got after putting air into them. I hope this helps!

I'm not aware of a calibration function to it. It's simply quite accurate out of the package.

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.

I don't think you can calibrate it. I haven't seen anything on the device or the app that lets you do it. Myself and 3 other people I know use it on a regular basis and have never had this issue. You might have a defective unit.

No does not require calibration. I compared with another scale and it was accurate.

Yeah you just have to calibrate it with your windows 7. Look it up on YouTube if you have to or google.

According to directions it is well calibrated before shipment and recommends recalibration cycle of one year. Directions tell you how to recalibrate. Seems to be working for me/

You can actually calibrate yourself. There are many sites available on line that tell you how to do it such as this one http://www.plasmatelevisions.org/article/plasma-television-tips/how-to-calibrate-your-plasma-tv.html

There is no initial calibration needed and I don't find anything regarding instructions on how to calibrate it should there be the need to in the future. I am assuming that since it works as most digital scales do, measuring changes in electrical resistance distributed to load cells, calibration is performed at the factory and would need to be performed by the factory in the future if there was a need to do so. I have had other digital scales which operated the same way and lasted for many years. It measures the same as a mechanical scale I have so I believe it is accurate from the factory. The only way to tell for sure is to locate a standard and periodically check to ensure it is calibrated against that standard.

I assume there is some measure of calibration at the factory. There is no calibration certificate, nor is there any way to calibrate the unit short of modifying the cable length. It is, however, the most accurate unit I have owned. Unfortunately, that accuracy is only with the original thermocouples - using other type K thermocouples from Amazon and other suppliers results in bizarre readings. It would be very useful to have a calibration function on the unit.

I have never calibrated mine and not sure how you would do it short of sending it back to factory. I have compared mine with several other test sets and also the system at my pool store and found it to be very accurate.

I don't think you can calibrate it but you can reset the unit by taking out the batteries, waiting a few minutes and placing them back in. This will reset the unit to its original factory settings. This will delete all previous data and settings.

I don't think so. I know you have to calibrate it yourself but it's very easy.

The only answer to your question that I have is that I didn't have to calibrate mine, and it seems to work correctly. This is not a hi-tech compass. It's pretty cheap overall. But if you can't afford a good one, it works in a pinch. It sticks to your window wherever it is convenient for you.

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.

It seems to calibrate itself upon startup. It will calibrate itself to zero if you turn it on with a container that you intend to fill already on it. As for it's need to be calibrated for accuracy, we'll we just have to trust to the gods of electronics. That said, I've never felt it might be even slightly beyond negligible where error is concerned. I'll buy another if mine ever poops out!

Possibly, depending on how off your colors are. Remember that sometimes calibration results in a reduction of the brightness of a screen or a projected image. This may detract from the viewing experience.

Mine wasn't easy to calibrate. You need to press a button on the back and go around a block - - - a complete 360 degree turn. You may have to do this several times to get it to be reasonably accurate. Good luck.

The documentation of this product did not say anything about calibration. Thus I assume it is already calibrated at the factory. But you bring up a good point. What if at some point the calibration may be off and what do we do? Documentation said nothing about this.
