Hi patdev.
Thanks for that. it would seem that the tester needs to have a back up and restore every so often to clean down unwanted test results.I regularly back up the data base of assets to usb, and I download the test results after each testing session so I can print reports and invoice the client, but unless I then do a restore from usb of the current back up to wipe the test results, previous test results will stay on the tester. In my case, there are two years of tests stored against the same assets. So I have 4500 assets that I test each year on a regular basis as a contractor. I have done this twice so now I have 9000 test results sitting there on the tester.
Maximum number of tests on the memory- 10,000. All I need to do is do a back up and then do a restore of the database of 4500 assets and that should also remove the 9000 unwanted test results from the machine. It would have been nice if Megger had made this clear in their manual as it would save a lot of time.Their software suite looks like it needs a makeover for PAT testers. It was the same with Seaward. Used a Supernova for six years.Great machine but Seawards software did'nt match the product in my opinion. Thanks again for your help and input from other members. Ron.
