25Set the Measurement ProtocolsEach installation will be slightly different. For this reason, measurement protocolssuch as the Sensor Calibration slope and intercept, Peltier Cooling Pulse optionsor Chamber Heating schedule should be set before deploying the instrument andchecked periodically throughout the experiment.Measurement Options: The default settings are a cooling time of 10 secondsand a wait time of 6 seconds. This ensures that water in the atmosphere of thechamber condenses and cools the thermocouple. A wait time of six (6) secondsallows for stabilisation of the psychrometeric wet bulb depression.Reverse Warming: Should not be required for a clean psychrometer andis an advanced option typically only required for very humid conditions.Chamber Heating: Should be employed whenever the psychrometer is subjectedto very cold temperatures at night that could induce condensation. If suchconditions are expected, A good protocol to follow is to employ chamber heatingbetween 5:00AM and 10:00AM to prevent the chamber form becoming colderthan the stem.ICT InternationalEnabling better global research outcomes in soil, plant & environmental monitoring.
