For the ranges indicated above consider with one decimal place. Example: -100 means -10.0
REGISTER 6 – INDICATION MODE
Defines the indication mode on the display of the sensor values readout. The
transmitter comes factory-configured with indication of temperature and
relative humidity.
Code
Description
0
Indicates temperature and relative humidity.
1
Indicates temperature and dew point.
2
Indicates relative humidity and dew point.
3
Indicates temperature only.
REGISTER 7 – TEMPERATURE VALUE (ºC or ºF)
REGISTER 8 – RELATIVE HUMIDITY VALUE (%)
REGISTER 9 – DEW POINT VALUE (ºC or ºF)
Shows the measured value in engineering units. The decimal point is fixed at
one place, the value is exhibited without the decimal point and must be
considered by the reading software.
REGISTER 10 – CONFIGURATION OF MEASUREMENT UNIT

The transmitter comes factory-configured with the value -9999.
7 SPECIAL CARE
The transmitter is an electronic module and, therefore, will need some
special care when handling it:
• When you open the transmitter to fix it, avoid any contact with the
electronic circuit due to the risk of damage caused by static electricity.
• Take maximum care when connecting the wires.
• When you close the case, the cover must be replaced correctly, thus
assuring the sealing quality of this model.
