Testo P2A software is used for the parameterizing, adjustment and analysis of Testo transmitters. For use with single or multiple transmitters P2A software features drag and drop simplicity which virtually eliminates programming errors.

Testo P2A software functions:

  • Parameterization of unit and scale
  • Setting of switching limits and hysteresis
  • Reset to factory setting
  • Query of min./max. values
  • Parameterization and adjustment history

In the P2A software, two different file types are used: The instrument and the parameter file. The Instrument file stores the parameters of a particular instrument. Using this file, the parameters can be edited and the instrument can be tested and adjusted. In the Parameter file, files are not tied to a specific individual transmitter and contain only parameter data/no history data. If you use various instruments of the same type, you can create parameter files once and transmit these onto the other instruments.
