SA9602M  
The SA9602M allows selection of the form of energy to be measured: forward  
energy, reverse energy, or bidirectional energy. Selection is achieved by means of  
the DIRI input. A table of possible settings for DIRI is shown below:

7. Rated Condition Select  
The user selectable output frequencies for the MOTOR output and LED pulse rate  
will allow a meter manufacturer to build meters for a 5-4-3-2 scaling ratio of rated  
current.  
The table below shows the various options which can be selected using pins R0 and  
R1.

Scaling of the frequency for the MOTOR drive output pulses takes effect in the  
same manner as shown for the LED output pulse rate.  
This feature is particularly useful in circumstances where a manufacturer requires  
a meter for use in a system rated for two different conditions, for exampe 230V/80A  
and 230V/40A. Previously such a requirement would have necessitated alteration  
ofboththeinputcurrentsensingresistorsandtheoutputmeasuring/countingblock.  
With the rated condition select, using R0 and R1, the SA9602M allows for the  
development of different rated meters requiring minimal changes.
