Figures of pressure input are valid for device type with internal pressure transmitter. Type with external pressure transmitter, has got parameters defined by this transmitter.
At the customer´s wish it is possible to secure a metrological verification of the transmitters at an accredited Calibration Service Centre.

Instructions for use

  • Before connection of the gauge into the pressure circuit, it is necessary to provide that the nominal range of device corresponds with measured pressure. Even a transient loading over the maximum allowable overpressure may cause a destruction of the measuring diaphragm! As for the difference gauge, the user shall assure that a pressure that is higher than the allowed non-destructive pressure corresponding to the nominal range should not unilaterally overload the measurement diaphragm.
  • At the gauge with internal pressure transmitter is necessary to check whether used medium does not chemically aggressive to any of used materials: silicon, duralumin, brass, plastic polyetherimide and Fluor-silicone sealing.
  • After temperature stabilization or anytime during operation is possible to make zeroing of the system, of course when ensure zero pressure. To activate this function press ENTER button on the front panel. For identification is used T symbol under main display. Controlling most of the other functions are operating normally locked with a password, see the detailed operating manual.
  • It is recommended to inform itself about using the device, in unlocked mode. Before unlocking the device for changes in settings, is recommanded to study operation manual. Or consult the necessary steps, because in locked part of memory are stored calibration data. Their changes result in distortion measurement accuracy!
