5、在日常運行時按實際工作壓力的2倍來配備壓力表。如工作壓力為0.2MPa，即配用0.4MPa量程的壓力表。這樣指針在刻度盤中間位置，垂直向上。安全閥的起座壓力也是按工作壓力來調(diào)整，壓力表仍有足夠的裕度應付超壓指示。
6、中國一般工業(yè)用壓力表共分為4個準確度等級，符合JJG52-1999《彈簧管式一般壓力表、壓力真空表和真空表》檢定規(guī)程對壓力表擬定的允許誤差。這4個準確度等級是:1級、1.6級、2.5級、4級。允許誤差（按測量上限的百分數(shù)計算）分別為±1%、±1.6%、±2.5%、±4%。
7、中國2005年新的數(shù)字壓力表檢定規(guī)程公布實施，符合JJG875-2005《數(shù)字壓力計檢定規(guī)程》。規(guī)定了壓力準確度分別為±0.01%、±0.02%、±0.05%、±0.1%、±0.2%、±0.5%、±1.0%、±1.6%。
