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.  
 
 Connecting logger to the computer by means of communication adapter 

 

Notice:

 USB connector can be located also at 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 (it has no influence to binary inputs record) 

 

select logging mode (cyclic or non cyclic) 

 

set for each channel type of temperature probe (Pt1000 or Ni1000) 

 

disable channels for logging with not connected temperature probe 

 

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 

 

enable or disable the option to clear minimum and maximum value memory by magnet 

 

set date and time of logger automatic switching ON logger or disable this option 

 

optionally  enable  to  control  logging  by  external  signal  (i.e.  logger  switch  ON/OFF  is 
controlled by binary input state at channel 4). Set required binary state for switching ON the 
logger from the menu of channel 4 parameters. 

 

select if record runs permanently or only if alarm is active 

 

if alarms are about to be applied, set both limits for each measured quantity and enable alarm 
(not relevant to binary inputs) 

 

optionally enable permanent alarm indication (alarm with memory) 

 

switch ON or switch OFF the display of logger
