DEEPENING SELF-MONITORING OF TEST AND VERIFICATION EQUIPMENT FOR CONTROL SYSTEMS: SELF-TESTING OF ANALOG INPUT BOARDS BEFORE THE FINAL ASSEMBLY OF EQUIPMENT. PART 1
A technique is proposed for testing analog input boards as part of test and verification equipment at the stage before the final assembly of the equipment and including standard tests of its self-monitoring. The technique enables to exclude errors during the installation of voltage dividers, calibration and operation tests, and makes it possible to automatically calculate the scale factors. A diagnostic PCB and software have been developed, prototyping has been carried out.
