  • HPP270 probe SW version 1.3.0 or above
  • Computer with Windows operating system and Vaisala Insight PC software installed
  • Vaisala USB cable (item code 242659) or Vaisala Indigo USB adapter (item code USB2) for connecting the probes to Vaisala Insight PC software
  • Device for powering the probe and viewing the analog output test current (range: 0.000 … 25.000 mA) sent by the probe
To test that the analog output of the probe is accurate, you can set the probe to output a fixed level of current (range: 0.000 … 25.000 mA) and view the reading to verify the output.
