Verify 3 phase installations from the socket outlet, without the need for probing. The MI-TPI makes 3 phase installation verification safer, faster and more reliable than traditional methods requiring probing of the socket outlet.
Simply connect the MI-TPI to the mains socket on your InstalTest 3017 or MI-3125 COMBO, select the test required on the tester, select the switch position on the MI-TPI then use the MI-TPI to switch between phases.
