I am looking to terminate a program if the probe tips have not been calibrated withing a certain time frame. The warning message just isn't enough for these guys... I think I need functions PROBEDATA() and SYSTEMDATE() but I am not sure what expression I need to evaluate for an "IF" flow control command. Anyone, do anything similar or have experience with this? Need to add a request in idea center. This seems like it should be an option in the probe setup.
