Current Price

 

 
The 

Current  Price 

screen  shows  the  price 

of electricity that  is currently in  effect. The 
rate  is  shown  in  cents  per  kilowatt-hour.  
The  current  price  is  usually  obtained  from 
the value you manually set in the 

Set Rate

 

screen.  To  manually  set  the  current  price 
value,  simply  press  and  release  both 
buttons  simultaneously.    This  will  put  you 
in  Configuration  Mode.    Move  through  the 

Restart

  screen  and 

Select  Language

 

screen  to  get  to  the 

Set  Rate

  screen, 

where you can change the current price value.  This new value will become the current 
price, and the Rate Label 

will be displayed as “Set by User”.  It is also possible to read 

the price directly from the smart meter.   If you manually set  the price to zero,  and  the 
meter supports this feature, then the 

EMU-2

™ will check the price with the meter every 

2 minutes. If no price value has been set 

– either by the smart meter or manually – then 

dashes are shown for the price digits.  For some utilities, the price can also be set by a 
special message sent to the meter by the utility.   This message will be displayed as a 
text message on the 

Message

 screen, and the price will be automatically set.  This will 

override any price value that has been set manually. 
 

 

 

Message 

 
The 

Message

  screen  will  display  a  text 

message  when  there  is  a  message  from 
your utility.  Your 

EMU-2

™ checks every 2 

minutes for a new message.  When a new 
message  is  received,  the  Indicator  LED 
Lights  will  flash  in  a  special  red-yellow 
sequence to show that  a new message  is 
waiting for you to see.  The envelope icon 
will  also  appear  in  the  upper  left  hand 
corner  of  the  screen  to  indicate  that  there 
is  an  active  message.    To  see  the  message,  use  the  buttons  to  go  to  the 

Message

 

screen,  and  the  message  will  be  displayed.    A  message  can  be  up  to  100  characters 
long.  If the message is too long to fit on the screen, 

a continuation character (“▼”) will 

be  shown  at  the  end  of  the  bottom  line,  and  the  message  will  automatically  scroll  up 
until the whole message has been displayed.  Once the end of the message is reached, 
it will start again after a short pause.  If the message requires an acknowledgment, you 
will automatically be sent to the 

Confirm Message

 screen.  Viewing the message resets
