UNIT AND INDEX ROTATION 
In general, the label side of the index base 
plate (front) should face the front of the meter.  
This allows the MTEK6000 EFC to also face 
the front of the meter. In certain applications, 
the MTEK6000 EFC and index can be 
installed 180
0
 from the standard position so 
that viewing of the MTEK6000 EFC is 
acceptable. To rotate the unit and index, refer 
to Fig. 2-3 and do the following: 
1.   Remove the 4 bolts at location A. 
2.   Rotate the base plate 180
0
 clockwise so 
that the front label side is now facing the 
rear of the unit. 
3.   Insert the 4 bolts into location B with the 
two lockwashers as shown. Fig. 2-3 
shows the index orientation after the 
rotation is completed. (DO NOT 
OVERTIGHTEN). 
COUNTER MASKING 
NOTE 
When you have changed the input drive 
value, be sure to remove the existing drive 
value label from the window and replace it 
with a new label that states the current input
