About the M-90 "Multiply display by" tag. 1

[VicThor1]

Hello! i hope you're having a good day. I recently got to work on a M-90 electronic register by G.E, model 734x002001. In the frontal part of the register, you can see a line that says "multiply display by". Since this relay was brought to me from an electrical substation i dont have a manual on me to read about it, and i'm confused as to what it means by "multiply display by". Any form of information would be greatly appreciated!

Thanks and good luck in your endeavours

The number will be the CT ratio times the PT ratio.
For instance if you are using 2000A to 5A CTs the CT ratio is 400.
If you are using 480V to 120V PTs the ratio is 4
400 x 4 = 1600
Multiply be 1600.
