, it has made fundamental changes to the circuit industry of conventional insulation resistance . Aided by the nice and fashionable design, MG-3120 have more and stronger functions , are easier to use and more reliable .
10. Do not test in infl ammable environment since spark may lead to explosion. 11. Stop using the instrument in case any metal is exposed because the shell or test wire is broken when the test is in process. 12. Be sure that the test wire has been removed from the test terminal and the function range selection switch is in the OFF position when you remove the rear cover to replace battery.
