Calculation formula for allowable error of pressure gauge!

Calculation formula for allowable error of pressure gauge!
Usually, it can be calculated by the following formula: allowable error=± (measurement upper limit – measurement lower limit) x accuracy level%.
For example, a pressure gauge with a measurement range of 0-10MPa and an accuracy level of 1.6 has an allowable error of ± (10-0) × 1.6%=± 0.16MPa.
It should be noted that accuracy level is an important parameter of pressure gauges, and common accuracy levels include 1.6, 2.5, etc.
By using this formula, we can clearly determine the allowable error range of a certain pressure gauge.
