Megger 6111-503 Offers

Features

• Included two duplex test leads with duplex hand spikes that have spring-loaded tips
• Duplex test leads measure both current and resistance when taking four-wire resistance measurements
• Spring-loaded hand spikes compress to make contact with a conductor
• Light-emitting diodes (LEDs) can confirm connection and the presence of live current and can indicate test pass/fail

A test probe, test lead, test prod, or scope probe transmits an electrical signal to a testing device for display and analysis. Designs range from simple test leads with probe-style or clamp-on tips to more complex oscilloscope probes and current detectors. Some test probes, such as basic test leads, have wires with tips for connecting to test equipment. Other test probes, such as voltage detectors, are built into the meter. Depending on what is to be tested, the probe might either be passive or have active parts that require external power to operate. Some probes require contact for testing, while some are capable of taking measurements from a distance. Some also have finger batteries, insulation, or other features to help protect the operator's hand from electrical shock or burns. Test probes are rated according to the amount of voltage, current, temperature, or other input they can measure. When choosing a test probe, the maximum amount of input that the probe can measure should match or exceed both the maximum amount that cab be tested by the test equipment, as well as that of the property expected to be present in the application.
