1. 5 s in case measured values remain stable Refresh interval is shortened to approximately 0 7 s only if measured values change Current consumption in this mode in usual operation is lower battery life is up to 4 times longer The FAST mode is recommend to use only in cases when slower display response is not acceptable Battery voltage drop below 7 V is indicated with blinking of BAT in default display mode displaying of actual values and FAST mode is automatically canceled to save the battery At the same time audio indication of alarms is automatically switched OFF If instrument is powered from external ac dc adapter internal 9V battery is replaced with rechargeable NiCd accumulator In usual operation from adapter accumulator is charged only with small current If accumulator is totally discharged its full charging in instrument takes approximately 100 hours Instrument with accumulator is not recommended for permanent operation without ac dc adapter plugged Accumulator works only as a standby source in case of power mains failure Switching ON and OFF the instrument r A m Switch ON the instrument by pressing ON OFF key After switching ON oag Hs the instrument all symbols on the LCD are displayed If the ON OFF key is My a g being held pressed all LCD symbols are displayed till the key is released rriti In usual operation instrument then starts the measurement mode and actual measured values are displayed Di2. selection LCD refreshment mode d REF alarm audio indication AUDD and clear the minimum and maximum memory CLR Commeter instruments passed the following electromagnetic compatibility EMC tests 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 EN 61000 4 5 class A Appendix A Accuracy of dew point measurement 100 100 T O 5 amp 80 Z ke o gt 80 a 1 5 C Tdp E 5 60 2 5 C Tdp ms 2 5 0 C Tdp 2 E 60 EM o Cc a z 20 oO TC 40 0 2 5 0 C Tdp 20 20 TA ace l 5 0 C m 40 0 60 20 0 20 40 60 80 100 120 20 0 20 40 60 80 100 120 process temperature T C process temperature T C TE COM C4130 10 7
3. COMMETER C4130 Digital thermo hygro barometer Instruction manual Manual for use of thermo hygro barometer COMMETER C4130 Instrument is 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 are displayed on a dual line LCD display Temperature is measured by RTD sensor Nil000 6180ppm Instrument compares all measured values except pressure tendency with two adjustable levels for each measured quantity Breaking the level is indicated by blinking the proper value on display and by audio indication switchable Instrument is equipped with minimum and maximum memory and Hold function Minimum and maximum values and Hold value are possible to display on the LCD anytime Technical parameters Parameters of measurement Temperature Range of measurement 10 to 60 C Resolution 0 1 C Accuracy 0 4 C Humidity Range measurement 5 to 95 RH Resolution 0 1 RH Accuracy 2 5 RH at the range of 5 to 95 RH Dew point temperature calculated from temperature and humidity Range 40 to 60 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 Atmospheric pressure Range of measurement 800 to 1100hPa Resolution 0 1 hPa Accuracy 2hPa at ambient temperature of 23 C Measuring interval and displa
4. The above procedure is necessary to repeat anytime after instrument is moved to the location of different altitude above sea level If you set the adding constant DIF to zero instrument will display the absolute pressure again Alarm indication and setting HOLD gt a UF F le es 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 If at least one alarm is active audio indication can be activated if menu AUDI On is selected see setting described above Alarm activation of each value can be disabled by setting lower alarm limit of the desired value up to its maximum This is indicated by OFF reading at the position of numeric value Value of upper limit of the same alarm is indifferent To set alarms press MENU key select ALAR from menu items and confirm by pressing ENTER key The following description of alarm setting is a model for alarm setting of all measured quantities Reading ALLO indicates adjusted lower alarm limit here air temperature Set the desired value by means of the arrow keys Press and hold the arrow key UP to make value increase fast Press and hold the arrow key DOWN to make value decrease fast Release the arrow key and press ENTER to confirm new
5. limit Reading ALHI indicates adjusted upper limit of the same alarm here air temperature Set the desired value in the same way as in above lower limit If needed it is possible to get back to lower limit setting of the same alarm by pressing DISPLAY key Press ENTER key to confirm new upper limit Then you are offered to set alarm of other input value here relative humidity The procedure is the same as the above temperature limit setting Alarm activation of each value can be disabled by setting lower alarm limit of the desired value up to its maximum This is indicated by OFF reading at the position of numeric value Value of upper limit of the same alarm is indifferent It is possible to leave the alarm setting mode by pressing MENU key New adjusted limits up to pressing MENU key are stored in memory TE COM C4 130 10 Battery replacement 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 setting of d REF and AUDI from menu selections and data in memory HOLD MIN and MAX will be lost For the same reason do not disconnect the battery for longer than 1 minute even if instrument is switched OFF If it happens or if battery is totally discharged it is necessary to set again in appropriate menu
