What is a resistance tester used for?
A resistance tester is an instrument used to measure the resistance of electrical components, cables, and installations. These devices help detect electrical faults and ensure compliance with safety and performance standards. Resistance testers are commonly referred to as insulation resistance testers, megohmmeters, or ohmmeters and are widely used across multiple industries.
Are resistance testers only standalone devices?
While resistance testers are often handheld or bench-mounted standalone devices, resistance measurement is also a key function in multimeters, multifunction testers, PAT testers, solar installation testers, and flash testers. These integrated measurement features allow for greater versatility in electrical testing.
