<p>The present invention relates to a pressure gauge testing method and an apparatus thereof. The pressure gauge testing method comprises: 1) a step of installing multiple test pressure gauges in a fixated jig unit using a connection joint; 2) a step of operating an opening control unit according to test conditions of the pressure gauge by controlling a display unit; 3) a step of testing the pressure gauge by generating selected pressure according to the selection in step 2); and 4) a step of displaying the test pressure on the display unit. The apparatus comprises: a pressure generating unit which generates pressure; an opening control unit which selectively applies the pressure generated from the pressure generating unit; a display unit which controls the operation of the opening control unit, and displays the applied pressure; and a fixated jig unit where multiple test pressure gauges are installed in order to measure pressure using the pressure applied by the opening control unit. In addition, the pressure generating unit, the opening control unit, the display unit, and the fixated jig unit are connected through a closed circuit.</p> |
