Input Drive Value 
Fig. 2-2 above shows gearing in the correct 
position for 10, 100, 1,000 or 10,000 cubic 
feet/revolution (ft
3
/rev) and 0.1, 1 and 10 
cubic meters/revolution (m
3
/rev). To change 
the input drive value to 5 ft
3
/rev: 
1. Loosen set screw a on compound gear A. 
2.   Lower gear A until its upper teeth engage   
  the upper teeth of compound gear B.

When changing a MTEK6000 in the field 
from a 10, 100, 1,000 or 10,000 ft
3
/rev drive 
meter with a 5 ft
3
/rev drive, the CF per Pulse 
In or Meter Drive parameter, must be 
changed to a value of 10 using software or the 
optional, external keypad / display. 
NOTE 
Electronic parameter CF per Pulse In or 
Meter Drive should always equal the meter 
drive value EXCEPT for 5 ft
3
/rev meters 
which should be set at 10. When switching to 
5 ft
3
/rev, the gear ratio is adjusted so that two 
revolutions of the input drive gear result in 
one revolution of the magnet and hub 
assembly, which sends a pulse signal to the 
instrument that equals 10 ft
3
/rev. The value 
can be changed using software or the 
optional, external keypad / display (see 
Appendix A for addressing). 
To change the input drive value to 10, 100, 
1,000 or 10,000 ft
3
/rev, return compound gear 
A to its original, factory-set position. Change 
the  CF Per Pulse In or Meter Drive 
parameter using software or the optional, 
external keypad / display (see Appendix A for 
addressing).
