10 Ambient
Temperature
Set when the ambient temperature is
below 30°C or above 55°C or when the
air temperature sensor is not connected.
If the user enters a fixed temperature,
this temperature must be within the
range 30° to 55°C.
11 Ambient Pressure Set when the ambient pressure is outside
the specified limits (55 to 120 kPa) or
the external pressure sensor is
configured but not connected.

measurement signal is outside
prescribed limits. It can be turned on
when the measurement path is
obstructed by insects, dust, precipitation,
condensation etc. If it persists, consult
with a Campbell Scientific application
engineer.
