Flex-T and Flex-T-RH modules
Wiring
The T and T-RH modules have no external connections as they measure the ambient air. The
temperature sensor is located inside the enclosure, at the bottom end. The humidity sensor is inside a
protruding sintered filter.
Temp+Humi configuration menu
Temp setup and Humi setup submenus:
These are for selecting the temperature sensor type and for
tuning the reading. For the -T and -T-RH models, these menus contain the factory calibration (fine
tuning) and should not be accessed unless recalibrating the transmitter. If the values are to be
adjusted, refer to the CS and ES model menu on page 9, it is similar. Please note that if the
Sensor
setting in the Temp setup menu is set to
Humi
, then the temperature reading is obtained from the
humidity sensor instead of the internal RTD. When the temperature (and humidity) have been factory
calibrated, the corresponding submenu will be password protected to prevent further adjustment.
Period
: Select the temperature measurement interval in seconds. 60…300 seconds is a good range for
most tasks. An unnecessarily short interval will consume the battery and the radio band.
Temp unit
: Select the temperature unit
°C
or
°F
.
Output
