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.
Use only probe connection cables provided by Vaisala when connecting devices to the indicator.
| CAUTION When powering the probe with the Indigo80 indicator, note that when there is H2O2 in the probe's environment, the probe must always be powered on. When powered on, the PEROXCAP sensor is heated, which permits using the probe in condensing H2O2 conditions, maintains measurement performance, and lengthens the probe's lifetime. When the probe is powered off, exposure to H2O2 condensation can cause the PEROXCAP sensor to fail within a day, and the sensor will not recover. |

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!

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, GMP252 connected). 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 .
