Abstract
Provided is a multi-range field full-automatic pressure and electric signal calibrating instrument, comprising: control components such as a shell, a power switch, multiple-interfaces, a display, a keyboard, and a gas pressure generating unit, a power supply unit, a pressure detecting unit, a gas pressure control unit and an electric signal detecting unit; the pressure output end of the pressure control unit is in parallel connection with pressure joints which are used for installing multiple pressure standard meters and detected meters with different ranges; the pressure control unit is in signal connection with the pressure standard meters; the electric signal detecting unit is in signal connection with the pressure control unit and the detected meters; the power supply unit can supply power by batteries. The calibrating instrument does not need to be externally connected with a gas cylinder and an alternating current power supply and can automatically generate a gas pressure and generate an accurate standard pressure; the design of the multi-range pressure standard meter can be suitable for various detected meters; the double detection and calibration for pressure and electric s…
