Up to two Vaisala Indigo-compatible probes or transmitters can be connected to the ports located on the bottom of Indigo80. You can connect and disconnect devices both when the indicator is powered on and when it is off.

Vaisala recommends using cables provided by Vaisala when connecting devices to the indicator. Cables and other accessories are available to order at store.vaisala.com. To connect GMP80P to Indigo80, use Vaisala probe connection cable 272075SP.

  1. If the indicator is powered and no devices are connected to it, the text Please connect a probe will be shown on the display.
  2. Insert the probe connection cable in one of the ports on the bottom of the indicator.
    • Note the orientation of the cable connector when inserting it
    • Hold the connector in place while turning its locking ring clockwise – never twist the connector body!
  3. Connect the probe to the M12-5F end of the probe connection cable.

    When the indicator recognizes the connected probe, it shows a notification on the display, for example, GMP251 connected. Note that Indigo80 identifies the GMP80P probe as GMP251.

    A probe connected to the leftmost port in the indicator is labeled  on the indicator's display, while the probe in the rightmost port is labeled .

  4. To change probes, simply detach the cable from the probe and connect a new probe.
For optimal measurement accuracy, the indicator guides you to check the connected probe's environment settings next.
