Mechanical Installation
Note:
In order to receive correct measurements, you must ensure that the measurement
transducer is subjected to the fl ow of the air to be measured.
1. Remove the mounting plate by loosening the screw.
2. Attach the mounting plate at the desired position with 2 screws.

Electrical Installation
Caution:
Wrong supply voltages and excessive loads on the outputs can damage the
transmitter.
Programming
The initial settings of the units are made in the factory to your order. The transmitters are
adjusted in the factory, so checking and readjustment at installation time are not necessary.
The units can be put into operation immediately after installation. Using the SW21 or HW4
software and a standard mini-USB cable, you can make the following settings:
• Scaling of the analogue outputs
• 1-point adjustment for humidity
• 1-point adjustment for CO
2
• General settings
Congratulations on the purchase of your new CF1 series measurement transducer!
Please read these short instructions through carefully before installing the unit.
General Description
The units in the CF1 series are universal measurement transducers for transmission of humidity,
temperature and
CO

Procedure
• Connect the power supply
• Connect the measurement transducer to the PC via mini-USB cable
• Programm the measurement transducer using the SW21 or HW4 software
• Remove the power supply (The measurement transducer must be isolated
from the power for at least 2 seconds)
Sources of Error
Measured values can be compromised by the following infl uences:
Temperature Errors
Through insuffi cient adaptation time, cold outer walls, heaters, direct sunlight, etc.
Humidity Errors
Through vapor, splashed water, dripping water or condensation on the sensor, etc. This does
not, however, impair reproducibility or long-term stability, even when the sensor is exposed
to high humidity or saturation with water vapor (condensation) for a prolonged period.
Carbon Dioxide Errors
Plants that are placed close to the measurement transducer neutralize the CO
2
. Objects or
persons that radiate carbon dioxide can also indicate an increased CO
2
content that is not
strictly part of the surroundings that are to be measured.
Contamination
Through dust in the air. The choice of sensor fi lter depends on the degree of contamination
at the measurement point, and the fi lter should be cleaned or replaced at intervals.
Periodical calibration of the sensor / transmitter
Both the temperature sensor and the associated electronics are very stable, and do not normally
have to be changed or calibrated after calibration in the factory. The long-term stability of the
ROTRONIC Hygromer humidity sensor is typically better than 1 %RH per year. For maximum preci-
sion, we recommend calibration of the sensors approximately every six to twelve months. In the
case of applications in which the sensor is subjected to pollutants, more frequent calibration may
be necessary. Calibration can be carried out by the user onsite, or in the laboratory or workshop.
The electronics do not normally need to be calibrated, and cannot be repaired in the fi eld. In case
of problems, get in touch with Rotronic AG Service.
