how do you confirm accuracy?

To quote the Instruction Manual: "When you press the START/STOP button, the Calibration Check System light turns on and the unit starts monitoring your readings using dual sensors. If the unit is accurate and functioning correctly, the Calibration Check System light remains lit during the measurement. If an error is detected, the Calibration Check System light flashes and "ER" will appear on the display." If this happens, simply turn off the unit, readjust the fit of the cuff on your arm, and start another measurement cycle with the unit. In general, the accuracy of this unit will be close enough to medical standards to satisfy the needs of your physician/provider.

I used it on my mother, she was then taken to the hospital after finding her blood pressure high and was higher at the hospital. I guess the best way would be to bring it to a hospital and see if anyone would be willing to help you there as you cannot expect all machines to work exactly the same even if it is a built series I believe it is accurate but until you can have it verified with hospital grade instruments don't trust it completely mine came great doesn't mean I trust it blindly, anyway I do hope my rather vague answer was somewhat helpful

I couldn't confirm. Returned it anyway because cuff was too big ... couldn't align it without it spinning around my arm. The few times I managed (with a 2nd person helping - which makes it almost useless anyway) the reading was wildly different (&gt; 20 points higher for both systolic&diastolic) than on my older machine. Didn't know which machine to believe ... have a gut feeling the older machine was more accurate.

I confirm using an old style, non digital Sphygmomanometer. That said, an exact comparison can never be made unless measurement made simultaneously - which isn't done. Even a reading with the Omron will differ when taken moments later. Consequently, accuracy is is considered OK when readings are consistently in the same range.

I did research and found through the American Heart Society, a list of all of the approved and trusted blood pressure machines. This was one of them. I am not expert, and if you want more accurate information contact your doctor or do further research.

I doubt that it is "accurate" in terms of being calibrated to any significant extent. I just line the up the disk to where I want it and it is very close to my floor pumps reading. I just use it to finish my ride if I get a flat. If I'm within 10 psi I'm happy enough to get home.

I don't know. It was so inaccurate I tried to return it then, when they didn't want it back, tossed it.

I have never checked it but my gut says it is fairly accurate. I have found that when the battery gets low it starts giving bad results.... It has an auto shut off but go ahead and turn if off your self to save the battery.

Sorry, but at the end I did not buy that scale, I bought one from another seller.Guess who makes them?: ChinaThe way I found out is to call the seller and ask him a tricky question; like: what about if scale accuracy is not what scale manual states? He will most likely state he will contact the mfr: Bingo!( For your information if the manual says scale has an accuracy of +/- 0.2 pounds of full scale reading, this means for example if you weigh yourself and scale reads 110 pounds +/- 0.2 pounds for a total of 109.8 pounds or 110.2 pounds.So Accuracy is OK. If the deviation is greater, scale accuracy is bad) Sorry, but at the end I did not buy that scale, I bought one from another seller.Guess who makes them?: ChinaThe way I found out is to call the seller and ask him a tricky question; like: what about if scale accuracy is not what scale manual states?

You can verify calibration every time by expelling all the air in the cuff and laying it out flat, then check needle to see that it is lying within the center of the indicator icon. If not, the pressure obtained would not be accurate and you may need to take it to medical supply place to have it checked or contact the manufacturer

I would be wary of the accuracy, there are "dead spots". I ordered two of these and both of them had a "dead zone" of about 6 degrees (from 76F-82F) where it would show it was 76 until it suddenly spiked to 82.

The specs on their website says the readings displayed will be in .05 degree increments but the accuracy is +- .2 degrees. So if you need more than a .2 degree accuracy, this isn't accurate enough for you.

It is very accurate. Just make sure you get one in the correct range you need. I may need another one due to this fact. The levels I check are at the very top of the range of the refractometer i bought.

Agree with the comment about doing things just right. Mine is very accurate. I will say I messed around with it a bit in the beginning to see what would make it go astray. Generally speaking though it is very accurate. I have had no problems.

I have had no problems with mine. Accurate as far as I have been able to determine.

It seems to be very accurate. The manufacturers specs would tell u exactly how accurate. Very happy with the unit. Got a new wireless phone system and had to move the Meade away from it because it wasn't working properly when to close to the new phones. Took awhile to figure that out.

I have found them not to be very accurate. I returned my first unit for that reason. The second unit was not much better. There are better auto units available. I don't use it anymore in my office.

You don't...you just double check it. This product is junk. Do not waste funds on it.

I took mine to DR's office to compare wrist unit to Dr's measurement. Low number was right on the money. Upper number read 6 higher on wrist unit.If you buy one, do the same thing. If you don't like the accuracy, return the unit.

Mine seems to give accurate readings...instruction sheet in box is fairly clear and easy to follow, even for an old timer like me.

Hi, I have one similar but I never had any problem with thve accuracy. Maybe you can request any advice send an e-mail to cuisinart customer service.I wait you can find the solution quickly
