CORRECTION AND CALIBRATION

6.1 Regular Correction

To ensure the accuracy of the measured value, the TR50 IAQ Sensor should be
corrected every year. The correction should be carried out when a large deviation in
the measured value occurs, even if it has been used for less than one year. This
chapter describes the correction environment and requirements needed on the
user's site; Honeywell can perform the correction via Niagara software tool at the
factory if the following environmental conditions are required for field
correction.

6.2 Correction Environment

• Temperature: 32 to 122 °F (0 to 50 °C)
• Humidity: 0-95% RH, non-condensing
• The TR50 IAQ Sensor needs to be placed in the indoor natural
environment within the above temperature and humidity range.
• There should be windows and no human interference with good air circulation.
• The room area for correction should not be less than 30 m
6.3 Calibration Standards Needed for Factory
Correction

6.3.1 Temperature and Humidity

Temperature and Humidity Calibration Standard:
After the temperature and humidity calibration standard and TR50 IAQ Sensor that
needs to be corrected are powered on continuously and synchronously for more
than 60 minutes, start to record the temperature and humidity value for
10 minutes, use the synchronous average value within 10 minutes overcorrection.
