3.3.4 SET SCREEN 4: SENSOR INPUT TYPE SELECTION
The new SM Quattro now has the ability to measure, display and record
Relative Humidity (as a percentage %H) on any of its 4 sensor inputs using
the Thermomax Humidity Sensor (CO429). The 4 sensor inputs can be
configured to read either Temperature or Relative Humidity. As a factory
default, all 4 sensor inputs are configured to accept temperature sensors.
The following paragraph describes how to change the configuration for each
sensor input if required.

temperature).
