The core part of the D Series is the digital calibrated dModul,
which processes the measurement values of relative humidity
and temperature individually. The values are compared to the
calibration values stored in the dModul and communicated
digitally to the transmitter electronics, where they are processed
to standardised current and voltage signals.
The housings of the industrial versions provide protection in ac-
cordance with IP 65. Only a single screw is required to close it
securely.

ESDprotectionadvice
The sensors of the D Series contain components, which can be damaged by the effects of electrical elds or by charge equa-
lisation when touched.
The following protective measures must be taken when the housing of the sensor is to be opened for connection or in situ
alignment:
• Before opening the housing of the sensor, ensure electrical potential equalisation between you and your environment.
• Pay particular attention to ensure that this potential equalisation is maintained while you are working with the
opened housing.

During the in situ alignment the sensor does not necessarily have to be taken out of the control circuit.
We offer humidity standards for alignment of the sensors (page 3: accessories).
Before calibrating the sensor, standards should remain at least 2 hours on the sensors.
The temperature must remain constant during this time. For the correct temperature according to the humidity standard used,
please refer to data sheet F5.2 Humidity Standards.
During calibration temperature and humidity must remain constant.
During calibration, especially during storage of data, uninterrupted power supply of the sensor must be provided.
During calibration the following measurement ranges are shown on the display/ are used for calibration:
CH 1: all sensors always: relative humidity, measuring range 0...100 % RH
CH 2: sensors
with relative humidity RH output (CH1)
and temperature °C output (CH2)
the programmed temperature range, unaltered
sensors
with other hx-values outputs
the standard temperature measuring range of -40...85°C

Changeofphysicalmeasuringvaluesandanalogueoutputscaling:
Based on the measured sizes of relative humidity and temperature you can select the below listed derived physical values.
All temperature values can be displayed in °F or °C.
The scaling of the physical values can be freely selected within the limits below.
The sensor is powered via USB for conguration - no power supply unit is required.
Airpressureandaltitude:
For the following physical values, the air pressure is relevant to obtain a correct reading:
•Mixing ratio [g/kg]
• Enthalpie [kJ/kg]
• Wet bulb temperature [°C/°F]
If a physical value is selected, for which the air pressure is relevant, the input eld automatically appears. The air pressure can
be entered either directly or indirectly via the altitude (m above sea level).
Adjustment:
The transmitter can be matched to the measuring task by means of adjustment. To do this, supply the transmitter with power via
the connection terminal and connect to the PC. This can also be done in situ using a portable computer.
There are two types of adjustment:
1. Offset adjustment: An offset in temperature and / or relative humidity can be entered.
Actual values are adjusted by this offset.
2. Adjustment with reference: By entering reference measuring values, sensor readings are adjusted to the reference.
Information:
The measuring accuracies specied in the technical data refer exclusively to factory adjustments.
The adjustment values in T & RH inuence all physical values.

Userinstructions
Dew formation Dew formation and splashes do not damage the sensor, although measurement
readings are corrupted until all moisture on and around the sensing element has
dried up completely.
Cleaning of
lters and
protective baskets
If necessary, soiled lters can be screwed off and rinsed carefully. Bear in mind the
sensors wil not measure accurately until lters are completely dry. Please do not
touch the highly sensitive humidity sensing element. Please ensure that the tempe-
rature sensing element does not touch the sensitive surface of the humidity sensing
element.
Cleaning of
the capacitive
humidity sensing element
Loose dust can be carefully cleaned off the humidity sensing element using distilled
water or by blowing the dust carefully off. Please do not touch the highly sensitive
humidity sensing element. Please ensure that the temperature sensing element does
not touch the sensitive surface of the humidity sensing element.
Damaging inuences Depending on type and concentration, agents that are corrosive and contain solvents,
can result in faulty measurements and can cause the sensor to break down.
Substances deposited on the sensor (e. g. resin aerosols, lacuer aerosols, smoke
deposits etc.) are damaging as they eventually form a water-repellent lm.
Position Install the sensor at a place where characteristic levels of humidity occur. The measu-
ring chamber should be located in streaming air. Avoid installation next to heaters,
doors or on outer walls. Avoid places exposed to the sun.
Do not position the sensor where ingress of water could occur.
To close the housing securely turn screw until dead stop.
We recommend that you lay the connection lines in a loop so that any water that
may be present can run off.
Not reaching the given minimum air speed can lead to measurement errors.
Connection The electrical connection must be carried out by qualied personnel only.
The sensor contains sensitive electrical components. When opening the housing,
make sure you comply with the electrostatic discharge precautions (ESD).
Please pay attention to the ohmic resistance according to the operating voltage (see
diagram on page 2) when using sensors with a current output. Else measurement
errors may occur.
Lines to and from the sensor must not be installed parallel to strong electromagnetical
elds.
If there is any chance of an electrical surge, please install surge protection devices.
