Humidity Compensation - Fluke Datapaq Food Tracker User Manual

Note that the conditioner remembers the last target temperature set, so it is
necessary to re-set it only if a new temperature is needed.
WARNING
The inside of the conditioner's heating chamber can get very hot.
The conditioner should only be used for heating humidity sensors.

Humidity Compensation

One of the inputs to the relative humidity measurement is temperature. In
some conditions, temperature measurements recorded by the humidity probe
are not as responsive as a thermocouple measuring air temperature –
particularly where the PTFE sensor filter is fitted. If this appears to be the case
in a given application, more accurate relative and absolute humidity
measurements may be obtained by using the air temperature thermocouple
instead of the humidity probe's temperature sensor. If this is done, the
thermocouple used for humidity measurements must be measuring the air
temperature and must be the vicinity of the humidity sensor.
When the run has been performed and the data downloaded to the Insight
software, select the Humidity tab in the analysis window and then click (or
select View > Analysis Options); under 'Humidity Temperature', select the
thermocouple that was used to measure the air temperature near the humidity
sensor.
