Fluke Corporation announced the availability of the its TL175 TwistGuard Test Leads with a manually adjustable test tip guard for use in different measurement environments. By twisting the test lead, the user can change the exposed probe tip length from 4 mm to 19 mm. When the tip guard is fully extended, the test leads are safety rated for CAT III 1000 V and CAT IV 600 V use. When the tip guard is retracted, the test leads are safety rated for CAT II 1000 V use. The new TL175 Test Leads are also Fluke’s first leads with WearGuard insulation. Each test lead is covered by two layers of silicone insulation: red or black on the outside, and white on the inside. If the test leads become nicked or scuffed and white insulation is visible, the user has a visual warning that the test leads should be replaced. Dual-layer silicone insulation resists melting if it comes in contact with hot surfaces and remains flexible in cold situations. The extra-heavy duty strain relief, built into both the probe-end and the plug-end, has been tested beyond 30,000 bends without failure. The universal input plugs work with all popular brands of digital multimeters with 4 mm input jacks.
