A multi-tester, also known as a multitool or multimeter, is a versatile device used to measure different electrical properties. It typically consists of several parts:
1. Display: This is the part of the multi-tester where the measured values are shown. It can be an LCD (Liquid Crystal Display) or an analog dial.
2. Selector Switch: The selector switch allows the user to choose the desired setting for measurement. It has various options such as voltage (AC/DC), current (AC/DC), resistance, capacitance, continuity, and diode testing.
3. Probes: The probes are the metallic tips or leads used to make contact with the circuit or component being tested. They typically consist of a red (positive) and black (negative) lead. The probes are inserted into the corresponding sockets on the multi-tester.
4. Sockets/Jacks: These are the openings on the multi-tester where the probes are inserted. They are labeled with symbols or abbreviations indicating the type of measurement to be made (e.g., V for voltage, A for current, Ω for resistance).
5. Function Buttons: Some multi-testers have additional function buttons that allow for specific features like range selection, data hold, or backlight illumination.
6. Power Source: Multi-testers are powered by batteries, typically located inside the device. The battery compartment may be accessed by removing a cover or panel.
7. Protective Casing: Many multi-testers come with a protective casing or holster to help safeguard the device from damage due to accidental drops or impacts.
