The Dilog 9073 appears to do all the necessary tests from continuity through to prospective SC, RCD testing and more.
At around gbp 450++, is it a reasonable choice? Any other alternatives of note?
Are they sold with a test/calibration certificate or are you expected to have them checked immediately after pruchase?
The 9073 is specifically advertised as a '16th edition tester' - are there any changes to tests in the 17th ed (due 2008) which this tester won't be able to handle?
most interested to hear any and all opinions
TIA.
