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.
R1 - 3.32Ω
R2 - 39.2Ω
R3 - 82.5Ω
R4 - 392Ω
R5 - 1kΩ
R6 - 3.92kΩ
R7 - 12.1kΩ
R8 - 43.2kΩ
R9 - 121kΩ
R10 - 267kΩ
R11 - 475kΩ
R12 - 825kΩ
R13 - 3.32MΩ
