General description Instrument iis designed for measurement of temperature, relative humidity, atmospheric pressure and pressure tendency. It enables to display the dew point temperature and atmospheric pressure corrected to the sea level. Measured values can be stored in programmable interval into internal non-volatile memory and transfer anytime to a PC.
Technical parameters Measured and calculated values Temperature: -10 to +60 °C Measuring range: 0.1 °C Resolution: ±0.4 °C Accuracy: Response time: t63 < 35 s, t90 < 60 s ____________________________________________________________________________________________________________ Air flow approximately 1m/s, temperature step 20 °C Relative humidity: Measuring range: 5 to 95 %RH Resolution:...
General Measuring interval and display reading refresh approximately: 0.7 s in FAST mode 0.7 to 5 s in dynamic mode Interval of refresh of pressure tendency display: 0.5 h Logging interval: 10 s to 24 h (in automatic logging mode) Total memory capacity: 1000 sets of all input quantities manual logging mode...
Electromagnetic compatibility: Device conforms in accordance with EN 61326-1 these norms: Radiation: EN 55022 class B Immunity: EN 61000-4-2 (levels 4/8 kV, class A) EN 61000-4-3 (intensity of electromagnetic field 3 V/m, class B) EN 61000-4-4 (levels 1/0.5 kV, class A) EN 61000-4-6 (intensity of electromagnetic field 3 V/m, class B) EN 61000-4-11 (class A)
Operation of the device Switching ON and OFF the device Switch ON the instrument by pressing ON/OFF key. After switching ON the instrument all symbols on the LCD are displayed. If the ON/OFF key is being held pressed, all LCD symbols are displayed till the key is released.
Press DISPLAY key to display pressure tendency (in hPa/3hours). Tendency is the difference between actual pressure and pressure before 3 hours. If the instrument is not switched ON at least 3 hours, pressure tendency is not available yet and symbol „--„ is display. Function HOLD (storing of actual measured values) and minimum a maximum memory Press HOLD key in the default mode (displaying of actual measured value) to store actual...

This item indicates if audio signaling of alarm indication is switched on (On) or switched off (OFF). Press ENTER key to change actual setting. Notice: if the battery voltage is low, audio indication is out of operation to reduce current consumption independently on this selection. Clearing of minimum and maximum memory of all values.
Alarm indication and setting It is possible to set lower and upper limit for each measured quantity. Breaking of the limit is indicated by blinking of the appropriate value on the display. If a new alarm was indicated (i.e. it was not active in the previous measurement), display starts to display the value out of limits.
Logging mode In logging mode measured values are stored to instrument internal memory. Memory is non volatile, i.e. if battery voltage drops or battery is disconnected, stored data will not be lost. Device can work in two logging modes: Automatic mode – actual measured values are stored to memory in adjustable time interval. Storing of the first value is synchronized with internal real time clock, so the memorizing is performed at sharp multiples of minutes, hours and days.
Instrument offers the possibility to clearing the instrument memory (ERAS). If you do not wish to clear the memory before new logging start, confirm selection ERAS NO by pressing the ENTER key. Now instrument displays adjusted storing interval. To modify the storing interval use arrow keys.
Clearing procedure is in progress. The duration is indicated by displaying of already cleared memory in % (digits 0 to 100). After memory is cleared it is possible to select one of three logging modes (MODE) by using arrow keys (non cyclic logging is indicated by symbol n.CYC, cyclic logging by symbol CYCL and manual logging by symbol Man).
Connection of the device to a personal computer For connection of the instrument to a personal computer is designed the USB communication cable (included in delivery). During time instrument is connected to the computer, there is a reading PC on the LCD display and measurement nor logging is interrupted. Keyboard of the instrument is disabled with the exception of ON/OFF key.
The PC software for the device Installation of program for PC with OS Windows Installation program is common for both versions of user program, i.e. basic (freeware) and optional (paid). Installed user program during first run asks licence key - if code is entered, perform the program registration according the displayed instructions and program runs as optional version (otherwise, the program runs in the basic version).

Viewing of measured values Measured values can be read directly from datalogger or from formerly created file on disk (command File - From disk, key F3). After reading a table of measured values occurs. Detailed information on file is available from context menu - menu occurs after clicking right mouse button on the position of table.
Battery replacement If battery voltage is low logging mode of the instrument is disabled. Low battery voltage is indicated on the display with blinking reading "BAT". It is necessary to replace it with new one as soon as possible. Battery is located under small cover on the instrument lower side. It is absolutely necessary to replace battery with instrument switched OFF, otherwise internal time and setting of d.REF.
