All tests can be carried out using the handsfree function. Simply turn the dial to the test required and push the HANDSFREE button. The test will automatically start once the leads are connected.

The test will be inhibited by the KT63DL until no voltage is present. The test leads auto null for continuity mode to ensure fast and reliable readings. You can also use the KT63DL in conjunction with the PAT ADAPTOR1 (available separately) to carry out dead PAT testing.
