9. After R3 has been adjusted, R2 is to be set so that the Converter output is zero. For CD-1
Converters, the Converter must be elevated on a 1 ft/sec span and R2 then set to obtain 74.3%
output (+/- 0.2%). For microprocessor-based 50XM1000 Converters, the Converter must be placed in
the bidirectional mode, low flow cutoff set to zero, and R2 set so that indication on the rate display
toggles between forward and reverse.

10. Following completion of steps 4 through 9, the system may now be returned to normal operation.
