3. logger is indicated by repeated short blink of yellow LED marked LOG with 10s interval If alarm is active yellow and red LEDs blink simultaneously To apply the alarm function it is necessary to enable from the PC alarm evaluation and at the same time set its lower and upper limits If measured temperature is inside of the limit range alarm is not active If measured value exceeds any of set limits alarm is indicated Memory alarm mode is selectable when once indicated alarm is indicated permanently till it is reset from the PC Alarm indication is also automatically reset with every new logger start If memory is filled in non cyclic logging mode record stops and logger switches OFF This state is indicated by accelerated blinking of red LED with 3s interval l 10s l logger switched OFF logger switched ON active alarm full memory Indication of the logger state beyond normal operation If yellow LED lights up after start extra long depending to memory occupation up to 12s initialization of the logger proceeds This can occur e g after totally discharged battery replacement In that case correct time setting from the PC is necessary If red LED blinks immediately after yellow LED do not mistake with active alarm indication end of calculated battery life is indicated logger is fully functional early battery replacement is recommended If only red LED blinks 2x with 3s interval battery voltage is low and
4. logger is not enabled to switch ON If logger was originally switched ON record is interrupted and logger is switched OFF Communication with computer can work for limited period of time Replace the battery as soon as possible l 10s l end of battery life low battery Procedure of switching ON OFF the logger by magnet IE LOG R3120 06 5 Start stop by magnet The function must be enabled from the PC before If only switching OFF by magnet is enabled it is of course necessary to switch ON the logger from the computer Switching the logger ON by magnet Plug magnet to guide slots from logger front side and wait approximately 1 s for yellow LED to light up After lighting up it is necessary immediately till it lights to remove magnet from guide slots and logger switches ON and yellow LED blinks every 10s If magnet is applied for more than 3s yellow LED goes out and logger remains switched OFF Switching the logger OFF by magnet The procedure is identical with the above procedure for switching ON If indication yellow LED does not light up to 1 second after plugging the magnet it is necessary to unplug magnet and repeat the procedure Battery replacement Low battery is indicated by red LED which blinks itself without yellow LED see tables above Replace the battery for new one If logger is operated often in temperature below 5 C or over 35 C and PC program indicates remaining battery capacity below 25

6. LOGGER R3120 Temperature and relative humidity logger Instruction Manual Instruction manual for use of temperature and RH logger R3120 Logger is designed for measurement and record of ambient temperature and relative humidity Measuring sensors of temperature and humidity are attached to logger Measured values including calculated dew point temperature are stored in selectable time interval to internal nonvolatile memory All logger control and setting are performed from the PC and password is applicable It is enabled to switch ON and OFF the logger by delivered magnet this possibility can be in configuration disabled It is also enabled to program automatic start in certain day and time for one month forward Switched ON logger every 10 seconds independently on logging interval updates MIN MAX memory compares measured values of each quantity with two adjustable limits for each quantity and exceeding of limits is indicated by LED diode alarm function Also memory alarm mode is selectable when alarm is indicated permanently till alarm memory reset Alarm function is enabled or disabled for each quantity individually Logging mode can be adjusted as non cyclic when logging stops after filling the memory In cyclic mode oldest stored values are overwritten by new In addition logging mode can be selected when logging is active only if measured value is out of adjusted alarm limits Stored values can be transferred from logger memory to
7. nnector can be located also from the computer front side After connecting the logger to the computer reading of logger info is enabled by means of the PC software and also setting of the instrument accordingly to the user needs menu Configuration Setting of instrument parameters Before logging start it is necessary check or optionally set the logger real time clock select suitable logging interval select logging mode cyclic or non cyclic switch ON the logger or switch OFF if it is about to be switched ON by magnet or automatically with delayed start enable or disable the option to switch ON the logger by magnet enable or disable the option to switch OFF the logger by magnet set date and time of logger automatic switching ON logger or disable this option select if record runs permanently or only if alarm is active If alarms are about to be applied set both limits and enable alarm optionally enable permanent alarm alarm with memory reset memory of MIN MAX values if needed check free space in data memory optionally erase data memory of the logger enter password if protection against unauthorized manipulation with the logger is necessary Logging interval between to subsequent measurements is specified by the user Memorizing of the first value is synchronized with the internal real time clock so the logging is performed at sharp multiples of minutes hours and days E g after starting the logging with the 15 minute interval

9. the first value is not stored immediately but after the internal clock gets the status of a quarter a half or a whole hour After starting the logging with the 6 hour interval the first value is stored at that whole hour to perform the storing also at 00 00 i e at the beginning of the day First storing is performed at 6 00 12 00 18 00 or 00 00hour at the hour from the above nearest to the logging start After communication with computer or after start by magnet logger automatically waits for the nearest whole multiple of time and then first measurement is performed This is also necessary to take into account when setting time of automatic logger switch ON Notice If logger operates as permanently connected to the computer using of magnet start stop is disabled To enable the logger control by magnet is suitable only in cases when possibility of unauthorized manipulation to the logger operation is eliminated 4 TE LOG R3 120 06 Indication of logger state in usual operation Switched OFF logger has both indication LEDs permanently OFF It does not do any function except eventual communication with the PC and the consumption from battery is negligible If any modification of configuration of switched OFF logger is done from the PC yellow LED blinks shortly at the moment of sending data to logger and then immediately red LED to indicate logger is still switched OFF After switching ON the logger yellow LED lights up for 2s and switched ON
10. the PC by means of communication adapter Communication adapter can be connected to the logger permanently data logging is not interrupted even if data download appears Logger evaluates minimum battery voltage and its drop below allowed limit is indicated by red LED At the same time remaining battery capacity is available in by means of the PC program It is valid if logger is operated at temperature from 5 to 35 C If logger is operated often outside of the above temperature range battery life can be reduced to 75 i e if displayed remaining battery capacity drops below 25 it is recommended to replace the battery Technical parameters Measuring parameters Ambient temperature RTD sensor Pt1000 3850ppm Measuring range 30 to 80 C Resolution 0 1 C Accuracy 0 4 C Relative humidity reading is temperature compensated at entire temperature range Measuring range 0 to 100 RH Resolution 0 1 RH Accuracy 2 5 RH from 5 to 95 RH at 23 C Dew point value calculated from temperature and humidity Range 60 to 80 C Resolution 0 1 C Accuracy 1 5 C at ambient temperature T lt 25 C and RV gt 30 for more details see Appendix A Response time with plastic sensor cover air flow approximately 1 m s temperature t63 lt 2 min t90 lt 8 min temperature step 20 C relative humidity t63 lt 15 s t90 lt 50 s humidity step 30 RH constant temperature Measuring interval alarm evaluation and M
