| Abstract: | Different precision pressure gauges were taken as experimental subjects to go mrougn tests unaer o scopes of pressure indication values for the evaluation of the uncertainty. The results showed that the Class 0.4 precision pres- sure gauges and vacuum meters were the optimum adjustable devices which can be adjusted by the Class 0.05 piston gauge. |
