QMAX PCB Fault Locator
I found this tester while checking on the QMAX V 200 in circuit tester. It looks like a high end tester and the waveform have some similarity with Huntron tracker (ASA). There is a link to the meter specification but the problem with the link was not working and it pointed to an error page. Fore more information about this tester and other related test equipment by Qmax please click on the photo above.
