I work for a company that wants to send a technician to our customers' sites to perform electronic service and upgrades. This person travels with various electronic equipment that we have calibrated by an approved vendor once per year. I have a question about that equipment that is bound to be handled and mishandled through its many travels. Is it possible to perform some quick and easy verification of the test equipment in the field without doing a full-blown calibration/verification procedure? The equipment includes a multimeter to check continuity, a waveform generator, a hipot tester, and a portable oscilloscope. Does anybody has some ideas on quick and simple ways to verify in the field that the test equipment has not been damaged in transit? We want to catch problems with our own equipment before we use it on someone else's equipment. I'm hoping there are some electronic gurus out there that can assist me. Thank you in advance.
