The equipment inlet is in the front of the cabinet. Measurements of air temperature and humidity must be taken at the front of the cabinet. Orient the air flow impellers parallel to the door inlet vents, so that air going into the door opening passes through the impellers and sensors.
The following illustration shows the positions from which to take temperature and humidity measurements. To achieve measurement accuracy, place temperature, humidity sensors, and probes close to the vents on the front door of the cabinet, but do not allow the temperature, humidity sensors, or probes to touch any part of the door.
