Factory settings 

If specific functions are not requested at time of order, the transmitter will be delivered with 
the following factory settings. The digits 7 and 8 are set to zero. In the rest of the tables in 
the manual, these two digits are left out, as they are not accessible from the PD 210 Display.

Note that the E5 scale value for standard version in the table is keyed-in in m³ pr. pulse, due 
to  the  corresponding  E1  setting  in  m³,  whereas  the  resulting  output  below  is  expressed  in 
litres pr. pulse.  
 
The above factory settings result in the following outputs: 
 

 

Standard version

 
 

Output2: 

 

1 litre/pulse (C 25 and C 38) 

 

 

 

 

10 litres/pulse (C 51, C 63, C 76 and C 102) 

 

Output3:
