Product Usage Instructions

Intended Use

The device measures the relative humidity and temperature of air or non- corrosive/non-ionizing gases. It can also display derived values based on these measurements. The device is suitable for various applications such as room climate monitoring and monitoring of storage rooms.

General Advice

Before using the device, read through this operating manual carefully to familiarize yourself with its operation. Keep this manual easily accessible for reference in case of any doubts or questions.

Safety Instructions

Follow the safety instructions below to ensure trouble-free operation and reliability of the device:

The device should only be used within the specified climatic conditions mentioned in the specifications section. Rapid temperature changes may cause condensation and potentially affect the device’s function. Allow the device temperature to adjust to the ambient temperature before starting it again.
Observe general instructions and safety regulations for electric, light, and heavy current plants, including domestic safety regulations (e.g., VDE).
When connecting the device to other devices (e.g., via PC), ensure careful circuitry design. Improper internal connections in third-party devices may result in voltage issues that can damage the device or other connected devices.
If there is any risk involved in running the device, switch it off immediately and mark it accordingly to prevent accidental restart. Return the device to the manufacturer for repair or maintenance in case of visible damage, non-compliance with specifications, or unsuitable storage conditions.
Warning : This product should not be used as a safety or emergency stop device or in any application where failure couldresult in personal injury or material damage.

Intended use

The device measures the relative humidity and temperature of air or non corrosive / non ionizing gases. From this values others can be derived and displayed instead of the rel. humidity.
Field of application
Room climate monitoring
Monitoring of storage rooms etc…
The safety instructions have to be observed.
The device must not be used for purposes and under conditions for that the device had not been designed. The device must carefully dealt with and has to be used according to the specifications (do not throw, knock, etc.). It has to be protected against dirt.
Do not expose the sensor to aggressive gases (like ammonia) for longer time.
Avoid condensation, as after drying there may remain residues, which may affect the precision negatively. In dusty environment additional protection has to be applied (special protection caps).

General advice

Read through this document attentively and make yourself familiar to the operation of the device before you use it. Keep this document in a ready-to- hand way in order to be able to look up in the case of doubt.

Safety instructions

This device has been designed and tested in accordance to the safety regulations for electronic devices. However, its trouble-free operation and reliability cannot be guaranteed unless the standard safety measures and special safety advises given in this manual will be adhered to when using it.

Trouble-free operation and reliability of the device can only be guaranteed if it is not subjected to any other climatic conditions than those stated under “Specification”.
- Transporting the device from a cold to a warm environment condensation may result in a failure of the function. In such a case make sure the device temperature has adjusted to the ambient temperature before trying a new start-up.
General instructions and safety regulations for electric, light and heavy current plants, including domestic safety regulations (e.g. VDE), have to be observed.
If device is to be connected to other devices (e.g. via PC) the circuitry has to be designed most carefully. Internal connection in third party devices (e.g. connection GND and earth) may result in not-permissible voltages impairing or destroying the device or another device connected.
Whenever there may be a risk whatsoever involved in running it, the device has to be switched off immediately and to be marked accordingly to avoid re-starting. Operator safety may be a risk if:
- there is visible damage to the device
- the device is not working as specified
- the device has been stored under unsuitable conditions for a longer time
  In case of doubt, please return device to manufacturer for repair or maintenance.
Warning : Do not use this product as safety or emergency stop device or in any other application where failure of the product could result in personal injury or material damage. Failure to comply with these instructions could result in death or serious injury and material damage.

Disposal notes

This device must not be disposed as “residual waste”.
To dispose this device, please send it directly to us (adequately stamped). We will dispose it appropriately and environmentally friendly.

Assignment of elbow-type plug (depending on type)

The type “current-” or “voltage output” is set by works and cannot be changed.
ATTENTION : If the humidity circuit is not supplied, the temperature output won’t give a valid signal! *) humidity value can be selected: rel. humidity, dew point temperature etc.

General installation instructions

To mount the connection cable (2-, 3-, or 4-wire depending on type of device) the elbow-type plug screw has to be loosened and the coupling insert has to be removed by means of a screw driver at the position indicated (arrow).
Pull out connection cable through PG gland and connect to the loose coupling insert as described in the wiring diagram. Replace loose coupling insert onto the pins at the transducer housing and turn cover cap with PG gland in the direction desired till it snaps on (4 different starting positions at 90° intervals). Re-tighten the screw at the angle plug.

Display Functions

Measuring display

During normal operation the selectable humidity display value is displayed alternating to the temperature in [°C] or [°F].

If the relative humidity in [%] should be shown, although other display is selected (e.g. dew point temperature, mixing ratio…):

press ▼ and ▲ simultaneous display changes between ‘r.H.‘ and measurand

Min/Max Value Memory

watch Min values (Lo): press ▼ shortly once / display changes between ‘Lo‘ and Min values
watch Max values (Hi): press ▲ shortly once /display changes between ‘Hi‘ and Max values
restore current values : press ▼ or ▲ once again /current values are displayed
clear Min-values : press ▼ for 2 seconds /Min values are cleared. Display shows shortly ‘CLr‘.
clear Max-values : press ▲ for 2 seconds /Max values are cleared. Display shows shortly ‘CLr‘

After 10 seconds the currently measured values will be displayed again.

Usage of Unit-Labels

As the transmitter is a multiple purpose device, many different display units are possible, e.g. g/kg, g/m3.
Therefore unit-labels (within scope of supply) can be shoved between the case cover and the front foil behind the transparent unit-window.
To replace a label, unscrew the cover, pull out the old label (if present) and shove in the new one.
The unit depends on the configuration settings “Unit”!
Please refer to table in chapter “10 Configuration of the device”

up. After that it will change to the display of the measuring.

Configuration of the device

Follow these instructions to configure the functions of the device:

Press SET until the first parameter UNIT appears in the display
If a parameter should be changed, press ▼ or ▲,
The device changed to the setting – edit with ▼ or ▲
Confirm the value with SET
Jump to the next parameter with SET.

Pressing SET again stores the settings, the instruments restart (segment test)

Please note: If there is no key pressed within the menu mode within 2 minutes, the configuration will be canceled, the entered settings are lost!
if higher values are needed, please check the sensor, if necessary return to the manufacturer for inspection.

Calculation : corrected value = (measured value – Offset) * (1+Scale/100)

Notes to the calibration services

Calibration certificates – DKD-certificates – other certificates:
If the device should be certificated for its accuracy, it is the best solution to return it with the referring sensors to the manufacturer. (please state desired test values, e.g. 70 %RH)
Only the manufacturer is capable to do efficient recalibration if necessary to get results of the highest accuracy! Humidity transmitters are subject to ageing. For optimum measuring precision we recommend a regular adjusting at the manufacturer (e.g. every 2nd year). Cleaning and checking of the sensors is part of the service.
