Mechanical Installation
A
Note:
In order to receive correct measurements, you must ensure that the measurement
transducer is subjected to the flow 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.
. a) Choose a representative position for installation:
2
Install the measuring head in a place at which the conditions of airspeed, humidity,
temperature and pressure are typical of the environment to be measured
b) Ensure that the ambient pressure at the point of measurement is kept as constant
as possible
c) Avoid installation close to heating elements, refrigeration units, or cold or warm walls
d) Do not install the measurement transducer in potentially explosive environments
e) Install the measurement transducer indoors
f) Avoid any physical contact with the sensor
g) Avoid installation in dusty environments
h) Avoid physical shocks or vibrations
Recommended Tools for Installation
• Phillips screwdriver
• Standard screwdriver
• Open-end wrench, 27 mm

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 (°C & %RH)
• 1-point adjustment for humidity
• 1-point adjustment for CO

• General settings
• Selectable analog signal ( Not selectable from V to mA output)
• Change CO (2000/5000ppm)

• Set CO threshold

Procedure
4..20 mA
• Connect the power supply
0..10 V
• 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 influences:
Temperature Errors
Through insufficient 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.
interface
Carbon Dioxide Errors
Plants that are placed close to the measurement transducer neutralize the CO
that radiate carbon dioxide can also indicate an increased CO
the surroundings that are to be measured.
Contamination
Through dust in the air. The choice of sensor filter depends on the degree of contamination at the
measurement point, and the filter 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 precision,
we recommend calibration of the sensors approximately every six to twelve months. In the case of ap-
