M12/5 M12/5 Male Connector Figure 7 Probe Body Pin # Function Notes Wire Colors in Vaisala Cables Power supply Supply voltage: Brown • HMP7: 18 ... 30 VDC • Other models: 15 ... 30 VDC Typical current 10 mA, max. 500 mA.
Attaching Probes to Indigo Transmitters Figure 8 Attaching the Probe to Indigo 200 Series 1. Insert the probe or the connection cable into the transmitter's connector. Use of connection cable is recommended for strain relief. 2. Turn the locking wheel of the transmitter to lock the probe or cable in place. Do not turn the probe or the cable itself, as that will damage the connectors.
Let the cable hang loosely to prevent condensed water from running along the cable to the probe head. Attach the probe body to a wall or other surface using the two mounting clips (Vaisala item 243257SP) supplied with the probe. Each clip attaches to the installation surface with one screw (screw hole Ø...

Compensation Setpoints 0334 Temperature 32-bit float Unit: °C compensation setpoint. If a value is written to this register, probe uses it when calculating relative humidity instead of its own measurement. When probe heating is in use, temperature must be written to this register to enable relative humidity measurement.
