3.2 Intended use
This portable pressure calibrator serves as a calibration instrument for the widest variety
of pressure measuring instruments and has been designed for mobile use as well as for
stationary workshop and laboratory testing. Through the combination of the integrated
electrical pump and the electrical modules, in addition to the traditional measurement of
current and voltage signals it also enables you to supply transmitters or sensors with a
max. of 50 mA (voltage (idling) = DC 24 V). The pressure calibrator can be used to carry
out and document a complete calibration process.
