3.4.1

Procedure

Use the following procedure to reset the Demand registers to zero:

Z

Press and hold the Demand Reset button.

• The LCD will initially display the 

GE Copyright

 message.

• The LCD will then display the 

Dmdreset

 event screen:

Z

Keep the Demand Reset button depressed until the screen updates 
and displays the current date and time. 
This signifies that the demand has been reset.
