Page 8: Operation Of The Device
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. -
Page 9: Function Hold (Storing Of Actual Measured Values) And Minimum A Maximum Memory
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 measured values to internal memory (indicated by short beep). Anytime it is possible to display stored values from MENU (see below). - Page 10 minimum and maximum memory of all values. Clearing of Memory is cleared after pressing ENTER key. Clearing is confirmed by reading YES on the LCD lower display. Press ENTER key to display values stored in the HOLD memory. Press DISPLAY key to display other stored values. Press ENTER key to leave this mode.

Page 11: Alarm Indication And Setting
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. -
Page 12: Logging Mode
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. -
Page 13: Logging Start With Clearing Memory And Logging Mode Selection
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. -
Page 14: Logging Stop From Keyboard
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). -
Page 15: Connection Of The Device To A Personal Computer
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. -

Visit www.cometsystem.com and click to link Programs. Download Program for dataloggers Comet to your computer. After running downloaded file logger.exe follow the Installator instruction. • Installation from installation CD: Insert installation CD to CD-ROM drive and wait for automatic Installator run. If Installator is not run automatically (depends on setting of operating system), find in file browser file CDSetup.exe in main directory of the installation CD and click to run. - Page 17 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.

Page 18: Battery Replacement
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. -
