APPENDIX A - SCANNER RESISTOR BANK

A bank of resistors is used to test the scanner board and scanner control board. The resistors can
be soldered directly to a mating connector, or optional calibration boards may be used. The low-
voltage testers use thirteen resistors and the high-voltage testers use fourteen. The values and
corresponding connector locations are shown below.
