Before using electrical testing tools you need know(2)

Feb. 22, 2017

Choose electrical testing tools that are suitable for industrial work, then keep an eye on them for abrasions and other damage that eventually occur with use. This way, you'll never have to worry about the failure of a test lead or probe—or the consequences there of.

4. Inspect test lead insulation.

Check to make sure the insulation is not nicked or cracked. With age the insulation material—whether PVC or silicone—can become dried out, brittle and susceptible to cracking.

5. A visual inspection will often catch any parts of the leads that have this problem.

Ensure there are no signs of gaps or cracks at the junction between the insulated wire and the molded banana plugs or probes at each end.

Verify correct voltage rating. Verify the meter and accessories are appropriately rated and designed for the system and equipment to which they will be connected.

6. Look for the IEC rating (e.g., CAT III or CAT IV) on your tester, and buy leads and other accessories that meet or exceed that rating.

Safety checking your equipment in the field can reduce hazard and ensure that all equipment is ready to go. Whether voltage testers or digital multimeters, a quick safety scan before working can also save time and money.
