What’s missing here?

May 2011

When was the last time you thought about the tires on your truck? Probably the last time one went flat or went missing. And chances are it was an inconvenience; you had to fix it or replace it, maybe you were late to work, or you had to make a purchase you hadn’t planned on.

Something we think of as a detail in the big picture - like the tires on a truck - can have big consequences if it’s not in place.

How a broken test lead is like a missing tire

Now think about the test leads on a multimeter. Most users only think about test leads when they add an alligator clip or when they break.

But it’s time to pay attention to the details. International regulatory and standards bodies are. IEC/EN 61010-031 is now in effect in Europe. This standard requires all test leads in CAT III and CAT IV environments to have no more than 4 mm (5/24 inch) of exposed metal. This regulation will likely be adopted worldwide within the next few years.

Test leads are essential to taking measurements with a multimeter. A good meter deserves a good set of leads, and Fluke test leads are as tough as Fluke meters.

Users should pay attention to the details. If a test lead is lost or broken, you can’t work. If leads are damaged, they may also be unsafe. And if the leads don’t meet applicable laws and standards, using or providing them to a member of your work crew could have legal implications.

Twist. Test.

Fluke is paying attention to the details. The newest test leads from Fluke, the TL175 TwistGuard™ Test Leads, provide five key benefits that will help you be more productive on your job:

  • TL175 TwistGuard Test Leads are the only test leads in the world with a manually adjustable test tip guard for use in different measurement environments. By simply twisting the test lead, the user can change the exposed probe tip length from ¾ in. (19 mm) to 4/25 in. (4 mm). Fully extended, the TL175 Test Leads are safety rated for CAT II 1000 V use. When retracted the test leads are safety rated for CAT III 1000 V and CAT IV 600 V.
  • 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 TL175 Test Leads become nicked or scuffed and white insulation is visible, the user has a visual warning that the test leads should be replaced.
  • These test leads are designed to last longer than any other leads currently available. The 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 TL175 Test Leads also offer screw threads at the base of the probe. This allows the user to add screw-on clips, probes and specialty tips. The threads improve measurement reliability, while the wide range of probe tips enhances measurement productivity.
  • The universal input plugs work with digital multimeters with 4 mm input jacks.

Test leads are a small detail, something that most users never think about. By using Fluke’s newest leads, the TL175 TwistGuard Test Leads, you can be assured that Fluke has already taken care of the details for you.
