Electrical Testing Instrument

1. Multimeters
The most widely used diagnostic tool, multimeters combine several measurement functions into one unit.
2. Clamp Meters
A clamp meter integrates a standard digital multimeter with a current sensor. It allows electricians to measure current without making direct physical contact with live wires.
3. Insulation Testers (Megohmmeters)
Also referred to as a "Megger," this is a specialized high-voltage ohmmeter used to check the integrity of electrical insulation.
