Connection of measured signals: shielded cable of 10 m maximum length with connector 

ELKA 3008V 

Measuring interval, alarm evaluation, memory MIN/MAX update and display refresh: 10 s 
Logging interval to memory: 10 s to 24 h (20 steps) 
Memory capacity:  

for non-cyclic logging mode 

8 126 records for each measured channel 

for cyclic logging mode 

 

7880 records for each measured channel 

  Specified values are maximum possible and can be reached only if record since last 

memory erasing was not interrupted.  

Communication with computer: via RS232 (serial port) by means of COM adapter or USB 

port by means of USB adapter; data transfer from logger via communication adapter is 
optical 

Real time clock: adjustable from computer, integrated calendar including leap years 
Error of internal RTC: < 200 ppm (i.e. 0.02 %, 17.28 s in 24 h) 
Power: Lithium battery 3.6 V size AA 
Battery life: 

typical (data download to PC is carried out about once a week): 5 years 
in continuous on-line mode with interval 1 minute: approximately 3 years 
in continuous on-line mode with interval 10 seconds: approximately 1 year 
Notice: The above battery lives are valid for logger operation in temperature from -5 to 
+35°C. If often operated outside of the above temperature range battery life can be reduced 
to 75%. 

Protection: IP67 
Operational conditions: 
  Operational temperature range: -30 to +70 °C 
  Operational humidity range: 0 to 100 %RH 
   Specification of outer characteristics accordingly to Czech National Standard 33-2000-3: 

normal environment accordingly to appendix NM:  AE1, AN1, AR1, BE1 

   Operational position: negligible  
  Logger installation: by self adhesive Dual Lock, applied to clean, flat surface 

Not allowed manipulation: it is not allowed to operate instrument with not connected 

temperature probes - if all probes are not connected, unconnected connectors should be 
protected by included connector cover. 

Limit condition: temperature -40 to +70 °C, humidity 0 to 100 %RH 
maximum voltage across  voltage input (IN3, IN4): -1 to +7 V dc 
Storing condition: temperature -40 to +85 °C, humidity 0 to 100 %RH 
Dimensions: 93 x 64 x 29 mm 
Weight including battery: approximately 130 g 
Material of the case: ABS 
 

 

Logger operation 

Logger  comes  complete  with  installed  battery  and  switched  OFF.  Before  operation  it  is 

necessary by means of installed user PC software to set logging parameters and other features. Free 
user program is available to download at www.cometsystem.cz . For communication with the PC a 
communication adapter is necessary (not included in delivery). For connection via RS232 serial port 
it  is  necessary  to  use  COM  ADAPTER,  for  connection  via  USB  port  it  is  necessary  to  use  USB 
ADAPTER.  Connect  adapter connector to  proper computer port and plug the adapter to  the guide 
slots on the side of logger.
