These test leads feature a flexible design which features an insulated alligator clip on one end and a removable probe tip on the other. The TL400 Test Leads provide excellent electrical contact and are designed with a range of different stainless-steel probe tips and insulated alligator clips. These test leads allow for testing current and voltage, as well as for probing short circuits and continuity. The TL400 Test Leads can also be used for Continuity/Ohms testing, DC Voltage testing, AC Voltage testing, and Amperage testing (up to 10A when used with the appropriate probe tip).
