Page 5: General
General 3. GENERAL We should like to congratulate you on your purchase of this new and innova- tive psychrometer; this outstanding instrument provides high-precision mea- surements for Pt100 sensors at a resolution of 0.001 K; it is thus also ideally suitable for highly accurate humidity measurement.. -

4. Safety instructions 4.2 Special notes on use If the device is brought into the work-room from a cold environment there is a risk that • condensation might form on the electronics. In measuring operations involving ther- mocouples pronounced changes in temperature may cause substantial measuring er- rors. -
Page 9: Measuring Instrument
Psychrometer a current of air. When the power supply is connected and the integrated fan starts operating, the moistened temperature sensor will, depending on air tem- perature and humidity, cool down by a measurable amount. Based on this psy- chrometric temperature difference the water vapor’s partial pressure e´ and thus all the variables associated with atmospheric humidity can be calculated. -
Page 10: Sensor Programming
5. Introduction 5.4 Sensor programming Measuring ranges For Pt100 sensors, two high resolution measuring ranges exist: -200.000 to 560.000°C and (as an option) -200.00 to 850.00°C. The calculation of the hu- midity variables relative humidity and dew point is rounded to two decimal places. - Page 11 Measuring operation For each measuring operation the maximum value and minimum value are ac- quired and saved to memory. These values can then be displayed, printed out, or deleted from memory. Measured value memory Up to 100 measured values can be saved manually. This data can then be shown on the display or output via the interface.

Page 17: Potential Separation
Potential separation 8.4 Potential separation When organizing a properly functioning measuring setup it is very important to ensure that no equalizing current flow between sensors, power supply, and pe- ripherals. All points must therefore lie at the same potential and / or any un- equal potentials that do exist must be electrically isolated. -
