APPENDIX B – CALIBRATION BOARDS
The low-voltage and high-voltage resistor banks, shown in Appendix A, are available from
Cablescan. The boards are constructed with two sets of connectors, one set on each side of the
board. The resistor bank is connected to one set, while the second set of connectors is used as a
shorting bar. During high-voltage testing, one of the tests requires all test points of each
connector to be shorted or connected together.
