Installing Probes
Install the temperature/humidity probe as the drawing.
Insert the connector of the probe straight into the sensor
connector of the Datalogger and firmly tighten the sensor-nut.
Use of sensor filter
A sensor filter is recommended to use when the probe is in a dusty environment.
Wear gloves and attach the sensor filter by wrapping around the outer
circumference of the probe window being careful not to touch the filter surface.
Note: The response becomes slow when the filter is used.
Replace the filter regularly depending on how dirty it is.
