1. Refer to Tab le 1 - or Tabl e 2 - in the Sizing Resistor Configuration section
below for the appropriate configuration. Once you have determined the
correct configuration for your drive size, cut and remove the appropriate
sizing resistor(s) (if necessary) from the Pulse Transformer board.
Sizing Resistor Configuration
The tables below indicate the value of the designated resistor (R1…R5) when left
in place on the Pulse Transformer board, or “Remove” when the resistor should
be cut off and removed from the board. “–” indicates that there is no resistor in
this position on the Pulse Transformer board.

IMPORTANT
This procedure requires a multimeter that measures resistance to thousandths
of an ohm.
