Using the Fluke TL175 TwistGuard Test Leads is quite simple. First, connect the test leads to your measuring device as you normally would. You can adjust the length of the test tips according to your measurement needs. When taking measurements, the patented TwistGuard will keep you safe by reducing tip exposure. Be careful not to nick or scuff the leads. If you see the inner color of the lead wire exposed, it means the leads are damaged and should be replaced. The leads can work well in both high - and low - temperature environments, but try to avoid extreme conditions. To maintain the leads, keep them clean and store them in a dry place. Don't subject them to excessive bending as they can withstand over 30,000 bends, but too much stress may still damage them.
