The Ideal Industries TL-102 is a set of probe-style replacement test leads for the 61-090 and 61-092 voltage testers and 61-702 and 61-704 clamp meters that is color-coded—one red and one black—for different testing applications and silicone-insulated for flexibility and resistance to heat and cold. The test leads have 90-degree, shielded banana plug connectors for attaching to the input ports of the testers and meters. They replace damaged or inoperative test leads for proper meter and tester operation.
Clamp meters, also called clamp-on meters, have two jaws that fit around a conductor to measure electrical current without cutting through wires, or touching or interrupting the electrical circuit. Available in handheld or benchtop models, clamp meters diagnose problems in electrical equipment, wiring, and power supplies. All clamp meters test for current. Some come with test leads and inputs for measuring voltage, capacitance, and resistance. They display information either in analog or digital form. Factors that influence meter choice include the electrical properties to be measured, the anticipated range of results, and the desired level of protection against transient voltage. Safety ratings are based on International Electrotechnical Commission (IEC) standards for low-voltage test equipment. IEC 61010 delineates four overvoltage installation categories. In general, a meter with a category IV rating will provide more protection against transient voltages than a meter with a lower category rating.
Ideal Industries manufactures test and measurement equipment, electrical supplies, and tools, among other products. The company, founded in 1916, is headquartered in Sycamore, IL.
