As per ANSI 12.2 does this simply mean a +/- 2% accuracy ?
0.5
A meter rule.
A metre rule.
Normally from 0 to 1 metre.
Tolerance basically means accuracy of an apparatus. For example, a meter rule(ruler) has an accuracy/ tolerance of 1 millimeter.
accuracy in mm and inches
If you have calibrated eyeballs
A meter rule is apropriate as it can measure up to unlimited meter while micrometer is suitable for diameter since it has a high degree of accuracy to small diameters in millimeters.
It is difficult to test the accuracy of the meter.
The various tests that are made before the installation of an energy meter are completed to ensure the safety and accuracy of the meter. These tests include EMC, vibration and core meter accuracy testing.
What's the function of meter rule
Extremely accurate.
"3 meters measure water flow90 percent thro meter 1 accuracy of 3 percent8 percent thro meter 2 accuracy 10 percent and2 percent thro meter 3 accuracy 15 percent what is accuracy combined?"if in metre 1 (0.9 X 0.03) = .027and in metre 2 (0.08 X 0.10) = .008and in metre 3 (0.02 X 0.15) = .003then total combined accuracy is 0.027+ 0.008 + 0.003 = 0.038 = 3.8 percent
As per ANSI 12.2 does this simply mean a +/- 2% accuracy ?
Accuracy, for a given size. The circular rule occupies space more efficiently and uses a spiral scale, so an 8 " Circular slide rule may be the equivalent in accuracy of 10 FEET of a linear rule.
To ensure accuracy when using a pH meter, it is important to calibrate the meter before each use using buffer solutions of known pH values. The meter should also be properly maintained and stored according to the manufacturer's guidelines. Additionally, performing multiple measurements and averaging the results can help increase accuracy.
