What is the percent accuracy rating?
1997553
The product description states "Displays volts, amps and wattage accurate to 3%"
1997554
Accuracy details how close to the actual value a measurement will be. For example, if this meter is used to measure power, and displays that the power used is 10 Watts, then the actual power used by the device being measured could be anywhere from 9.7 to 10.3 watts. 3% (.03) of 10 Watts is .3 Watts (.03*10=.3), and that .3 Watt variance could be either higher or lower from the measured 10 Watt figure displayed.

My answer is probably useless... But I replied so you weren't left hanging. I hooked up my computer to it and set the cost for kW/h to what I think my service charges. After one month it cost me more to just run my computer than my entire cilco bill was. I am betting that is just me who did it wrong. I haven't tried very hard with it. I don't want to steer you away if you are planning on using it seriously and you are good at what you do. I would say it was of by 400%, but could have been me. THE DISPLAY IS VERY DIM.

the spec says 3%. But on my unit i just received I just made the following measurements using multiple professional HP and Fluke high accuracy instruments (I'm an electrical engineer). TS-836A said 122.3V, instruments said 122.5V; TS386A said 769mA, instruments said 725 mA -that's a 5% error. Predictably the Watts was off 5% too as it is just a calculation. I'm about to leave a comparison against the Kill-a-watt in the reviews

At that range it's not very accurate.....you better off with the gamo pt -85 accurate at that range.

I use it as a guide to see how active I've been. Room for error can be 15-25%. Mine has been very accurate with my workouts and strides.

Usually quite accurate. If you can get it to update the maps and software. When it does make an error, you may wind up down a narrow dead-end road or 15 miles out in the middle of nowhere. The second time I tried to update mine, it failed to update and crashed and became useless. I bought a Garmin.

Monika,This item comes with a certificate of calibration which states. Calibration equipment: calibrated and certified by SGS, accuracy of calibration plus minus 0.5 percent. Hope this helps. Joe

I have used this product to control a crane humidifyer in the range of 70 to 90%. I used this device to control a solid state relay that turns on a 120VAC receptacle into which the humidfyer is plugged. I have confirmed the sensor calibration at 70%. I've used it fot two years and think it has been a very economical solution for my application. I can not provide assurance of its accuracy at 45% - though I think it would probably be fine.

DC, Range 400A, Accuracy + or - (1.5%+5), Resolution 0.1A ; Range 1000A, Accuracy + or - (2.0%+10), Resolution 1A ; AC, Range 400A, Accuracy + or - (2.0%+5), Resolution 0.1A ; Range 1000A, Accuracy + or - (2.5%+10), Resolution 1A

I could not find that type rating on the info data. We bought it based on some our friends recommendations.We have found it to be satisfactory if one follows the instructions provided.

Not sure what you mean by accuracy tolerance but it is accurate to .01g as for the calibration weight you need 200g. As for overall tolerance I find it to be kind of flimsy and it is noticibly larger than a zippo.

Bruce, this tuner is supposed to be +/- 1 cent on accuracy. I do know these tuners have brought out a better sound on my guitars vs an older stand alone chromatic tuner that I was using because of placement variation. For the price I don't think you can beat them.

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

Resolution and accuracy are two different things. Resolution is the detail you see on the display (i.e. 0.05 degree increments). Accuracy is the error interval in which the device's measurement falls as opposed to the actual physical angle (i.e. plus/minus 0.2 degree or a 0.4 absolute degree interval). So, for example, if your display reads 22.35 degrees, then the actual physical angle of the object is between 22.15 and 22.55 degrees. As you see, the absolute value of the error interval is 0.4 degree. That's less than half a degree of error and suitable for most carpentry applications. It is not, however, considered accurate enough for high precision metal work.

Accuracy CW ± 2%; CCW ± 3% we bought it to verify our torque wrenches for ISO standards. It works good and comes with a certificate for verification

I checked the accuracy by using a charcoal canisters {2 separate tests} from a good, local lab...so I trust the lab results were accurate as benchmark. The meter read about 45% higher. The canister was 9 and meter about 13 on one test, and appx same on second test. So I just adjust divide my meter reading my 1.45. So if meter reads 2....divide by 1.45=1.38. In other words....if you increase 1.38 by 45% you have 2.00.

According to Scientific Equipment of Houston, the manufacturer, these are accurate to +/-5% depending on the volume being measured. This is the disclaimer provided for all of the lab equipment they sell no matter if it's glass, plastic or whatever. I use them for measuring hydroponic nutrients and find them to be very accurate and as accurate as any other measuring equipment you can find for less and than $100.

Yes. Just make sure you enter the correct make, model and, year. So, you can get accuracy result. I hope this helps.
