This Resistance Calibration Verification Board allows you to periodically verify proper resistance measurements of the tester, including after calibration, storage, or relocation. We recommend verification once a quarter.
A set of resistances and a couple of diodes cover all 64 test points to ensure that none of them is off-measuring. This board is sold as a single board, not a set of 2. You should manually plug the board to the second bank in the control module and to any additional banks if expansion modules are present to cover all test points of the system.
For low voltage operation only. Not intended for HiPot.
