Operational Details: 

 

The  energy  based  Entity  is  a  versatile  meter  with  all  the  features  needed  to 
implement  for  a  robust  electrical  system.  It  can  be  configured  to  suit  for  the 
measurement of energy. There are two types of operational Mode in this unit such as 
Programming Mode and Run Mode. 

After  supplying  power  (80  to  270  VAC),  the  unit  will  display  with  power  receiving 
information such 

as “---TRINITY ”, CT Ratio, Device Id (Only In the KWh variant) 

and then enters into Run Mode by default with the following display. 
 
 

 

 

 

 

Programming  Mode: 

 

The unit has programmable parameters CT-Primary, CT  Secondary and Device Id and  
is also easy user interface by pressing three keys such as,       ,       and         

 

 
 
Setting  CT-Primary: 

 

The CT-Primary is freely programmable from 5 to 5000 A of which 5 to 200 can be 
set  with  the  steps  of  5  and  200  to  5000  with  the  steps  of  25,  and  hence  the  CT 
setting falls onto the standard rating of user’s desire. The CT setting thus gives the 
true current value for CT operated meter in your electrical installation system. 

 

To set the CT-Primary, proceed the following instructions. 

 

1.  In Run Mode display, press 

 key for about 4 to 5 seconds continuously. The 

unit will enter into Programming Mode with the following display. 

2.
