Can you use the precision pressure gauge of level 0.25, measuring range (0~10) and MPa to verify the general pressure gauge of level 1, measuring range (0~6) MPa? Why?
Yes, measurement pressure gauge inspection requirements, standard table accuracy requirements greater than or equal to 4 times
There is no problem with the standard meter. The measuring instrument should use a 0.05 stage piston pressure gauge
According to the verification regulation requirements, the measurement ratio is 1/4, that is, the basic error of the standard device is not greater than the basic error of the checked table 1/4.0-10MPa, the basic error of the 0.25 standard table is 10*0.0025%=0.025MPa0-6MPa, the basic error of the 1.6 stage general pressure meter is 6*0.016*=0.096MPa0.025>0.096/4So, if you follow the rules strictly, this is out of the question. You must use the 0.4 or 0.25 stage precision watch of range 0-6MPa as standardIn other words, if you need a formal and effective certificate of approval, you can't; check yourself for reference, or you can
