Press  the  button  again  to  get  value  of  temperature  
corresponding to output current 4mA (output voltage 
0V). 

 

 

 
 

After next pressing of  the button LCD shows value 
of  temperature  corresponding  to  output  current 
20mA (output voltage 10V). 
 
 

 
Press button again to end info mode and display actual measured value. 

 

Notice:

  during  info  mode  no  measurement  and  no  output  current  (output  voltage)  generation 

proceed.  The  transmitter  stays  at info  mode  15  s,  and  then  automatically  goes  back  to  measuring 
cycle.  

 
 

 

Procedure of modification of transmitter adjustment: 

 

Device  adjustment  is  performed  by  means  of  the  optional  SP003  communication  cable, 
connected to USB port of the PC. 

 

It  is  necessary  to  have  installed  configuration  program  TSensor  on  the  PC.  It  is  free  to 
download at 

www.cometsystem.cz/products/reg-TSensor

 

During installation please take care about installation of driver for  USB communication cable. 

 

Connect  SP003  communication  cable  to  the  PC.  Installed  USB  driver  detect  connected  cable 
and create virtual COM port inside the PC. 

 

Unscrew  four  screws  of  the  device  lid  a  remove  the  lid.  If  device  is  already  installed  to 
measuring system, disconnect leads from terminals. 

 

Connect SP003 communication cable to the device. Display must light up, or at least must light 
up all symbols for one second (if LCD was switched OFF by program before).  

 

Run  installed  TSensor  program  and  select  corresponding  communication  COM  port  (as 
described above). 

 

When new setting is saved and finished disconnect the cable from the device and place the lid 
back to the device.

 

 

Error States of the device 

Device  continuously  checks  its  state  during  operation.  In  case  error  is  found  LCD  displays 

corresponding error code: 

 

Error 0 - 

first  line  of  LCD  displays  „Err0“.  Check  sum  error  of  stored  setting  inside  device’s 

memory. This error appears if incorrect writing procedure to device’s memory occurred or if 
damage  of  calibration  data  appeared.  At  this  state  device  does  not  measure  and  calculate 
values. It is a serious error, contact distributor of the device to fix.
