|Measurement output seems incorrect
||Installation location is not representative of actual conditions you

||Verify the installation location and relocate the probe if
|Heat conduction along probe head and cable is interfering with
||Follow the installation recommendations for cases when temperature
of measured environment differs greatly from ambient. See Installation.
|Probe is in need of adjustment
||Calibrate and adjust the probe.
|Probe status indicator LED is red
||Probe is in error state
||Connect the probe to Insight software or an Indigo transmitter and
read the error message(s). See Vaisala Insight software and Error messages.
|Probe status indicator LED is off even though power is on
||Probe model is HMP1
||To prevent the warming of the indicator LED from causing a slight
measurement error, HMP1 keeps the indicator normally off (even when power is on). If
the probe is in error state, the red LED is shown.
|Values of measurement parameters stop changing for a few
||Probe is performing a sensor heating function such as sensor purge or waiting for
the sensor to cool down
||Wait for the function to complete and measurement parameters to be available
