Does it need to be calibrated ?

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

This pedometer simply counts steps. To know how far you have walked, you need to know how many steps it takes you to walk one mile. Reset the pedometer to zero, walk one mile, and see what it has recorded - that's your "calibration". I do this at least twice a year because as they age, dust or fine dirt seems to slow down the mechanism and the steps per mile changes. For me, the steps per mile ranges from 1900 to 2200.

No. This pedometer has a 98% accuracy rate. It has the JW200™ engine which is the Digi-walker engine.

There is no way to calibrate this pedometer. If your looking for a reliable, and calibrated pedometer, I'm afraid this one will not work for you.

No. It is a simple pedometer with one button, a reset to zero steps. The "instructions" that came with it said it was sensitive to differences in walking and would adjust automatically. It has worked fine for me.

No, this Pedometer is simple in that degree. Is very accurate in the amount of steps displayed as to the steps I take---I have counted the steps and then checked the Pedometer to see if the reading is the same and is pretty much right on.

It can be calibrated the same way any torque wrench is cal'd. Any precision calibration shop will be able to do it. Scott Reilly, A&P; Mechanic

I found no calibration feature. You can contact the manufacturer and they will answer your question further.

I do not believe this unit required calibration. I checked it against some 1 to 4 oz letters I had and it registered correctly. I have used this for up to 13 oz, including flats, and have sent a lot of mail using it. So far, no issues. Good unit for the price.

You have to calibrate it. It was beyond me. But i had a friend who'd done well in chemistry. He was unsuccessful in getting a reading that made sense, but I blame that more on him, than the reader. I would look for a pre-calibrated meter for someone with limited tech skills. i needed it to test PH in pond water. I have several mud ponds. The PH is a little different in each of them.

No, it should be calibrated. Make sure you have it set to read salinity. The pool water should read around 0.3 percent, or 3 ppt or 3000 ppm. My chlorinator also reads the amount of salt and it agrees well with this instrument.

Maybe you have a defective one. I am on my second and calibrate using a pH 7 neutral solution. Using the screwdriver provided and the little screw on the back I have no problem moving it up or down. This is my second one and both worked flawlessly.

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.

For me it was ready to rock and roll. However I would suggest you run some basic tests to make sure yours is, and that the calibration is to your personal liking.

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

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.

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.

No it doesn't need to be calibrated. I would say it's a guide. We had fun over Christmas testing everyone from people who drank nothing to a person that did a shot before testing. It seemed pretty accurate.

No calibration needed, although it is always a good idea to test when you have not had any alcohol to make sure it reads zero at that time. Remember, it is not meant to be as accurate as the equipment used by the sheriffs. It is a way to keep yourself in check when you are out drinking.

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.

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.
