I have developed a LabVIEW program to replace the original DBase driven program to operate the MARKENRICH RT-250 Relay Tester. With the lost of support from Microsoft on DBase files, the origianl program is useless on the new OS or/and updated office products. I made use of .ini and excel format files to configure and control the test sequence and test parameters.
I am not sure if there is any interest, but I have the completed program and can advise on its use.
