JPI 201 K-factor  = about 29.xx – 30.xx
JPI 231 K-factor  = about 19.xx – 20.xx

Beech K-factor    = about 85.00  – (3 wire)    * Our FS-450’s and EDM’s hook up to only 3-wire type transducers only.

Piper K-factor    = 84.00 to 85.00 -(3 wire)    * Our FS-450’s and EDM’s hook up to only 3-wire type transducers only.

Hoskins K-factor = 84.00 to 85.00 -(3 wire)    * Our FS-450’s and EDM’s hook up to only 3-wire type transducers only.

Set the approximate value and then fine tune using procedure in the pilot’s guide.
