Mine arrived perfectly ready to go. No calibration needed. Great scale. Works perfectly for my needs and looks sleek and modern.

It self calibrated when I first set it up. I have moved it twice since then with no problems.

calibration settings are usually set at a personal level. You have but to refer to available reviews by buyers to check settings of various users. Such information may serve as a starting point for your own liking.

Sounds like it's defective. I never really calibrated mine, but it seems to work fine. Sorry! Send it back

I have owned a couple of them, and I have never calibrated...so I would say no...it's a very simple, pedometer...

It does not need calibration but you must let it stay in soil undisturbed for minimum of 5 minutes until it displays final PH reading and the PH range is less than 5 and above 7

Hi Zitch I just look up the operating instructions on line and it does not indicate that you can calibrate this gauge. I have checked mine against a few manual gauges and it was very accurate. Hope this helps. Dave.

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.

It did not need calibration although I did check to make sure it was correct when I received it. I have owned it for over a year now and I keep it turned off when not using it so the batteries are still strong. I did not buy an adapter. I truly love mine. As I get older, it gets harder and harder to see, so having the weight displayed right up close is wonderful. I don't think you will be disappointed.

I don't think there is any calibration necessary. There are different frequency choices you can select. It seems to measure whatever emf radiation is in the area.

Yes it does, and once calibrated it is quite accurate. I would advise getting a calibration weight if you don't have one.

Yes it can be calibrated with a wrench on the back side of the dial.. Hope that helps you.

It should be done approximately every 12 months. Calibration is dependent upon the environment obviously. You can find the calibration information for a 117 here: http://media.fluke.com/documents/114_____cieng0100.pdf

I did not calibrate it except to test against another thermometer. It was right on. No adjusting is possible to the reading.

I didn't calibrate mine. I haven't compared it with other thermometers, but it seems to be working just fine.

I saw no way to calibrate it, and contacted the manufacturer when my chlorine reading was way off. They did not mention calibration. I tried 2 kits and gave up after my chlorine reading was way off on both.

I do not use the battery and only calibrated when I got it. I unplug it plenty and have never had to re calibrate.
