5. START-UP PROCEDURE 

5.1. Before start-up you should check that flowmeter

’s operation parameters 

specified  in  the  Passport  correspond  to  data  entered  in  the  flowmeter 
memory. 

5.2.  Parameters  of  PEA  are  entered  according  to  the  Operation  Manual, 

Sections 2.1 Part II. 

5.3. Processing of measurement results is adjusted according to the Opera-

tion Manual, Section 2.4, Part II. 

5.4.  External  devices  (analog  recorder,  modem,  etc.)  are  connected  to  the 

flowmeter,  communication  system  and  flowmeter  outputs  are  adjusted 
according to the instructions given in Part II of the Operation Manual. 

5.5.  Current  date  and  time  are  checked  and  set  if  necessary  (see  Section 

2.5, Part II of the Operation Manual).  

5.6.  The  device  should  be  switched  into  the  OPERATION  mode  (a  jumper 

should be removed from terminal J4). Terminal J4 should be sealed. If 
necessary, two fixing screws are sealed from the front panel side. 

If the  parameters are set  correctly, the flowmeter displays flowrate 

measurement results. 

5.7. Requirements  for  mounting  location  and  operating  conditions  specified 

in this operational documentation are based on the most typical factors 
affecting flowmeter performance. 

The  external  factors  that  cannot  be  foreseen,  evaluated  or  tested 

by the manufacturer during designing may exist or appear on site. 

In this case such factors should be eliminated or flowmeter should 

be placed in other location.
