7 best multimeter measurings
A multimeter, also known as a multitester or VOM (Volt-Ohm meter), is an essential tool used to measure various electrical quantities in electrical circuits.It typically measures voltage, current, and resistance, but some models can also measure other parameters like capacitance, frequency, and temperature. Here are the primary measurements a multimeter can perform:
Voltage (Volts - V): A multimeter allows you to measure the voltage in an electrical circuit, whether it's AC (Alternating Current) or DC (Direct Current). It provides information about the electrical potential difference between two points in the circuit.
Current (Amperes - Amps - A): Multimeters can measure current, indicating the flow of electrical charge in a circuit. Current measurements can be AC or DC, and the multimeter must be placed in series with the circuit to measure it accurately.
Resistance (Ohms - Ω): Multimeters can measure resistance, which indicates how difficult it is for electricity to flow through a component or a portion of a circuit. Lower resistance values indicate better electrical conductivity.
Continuity Testing: This feature allows you to determine if a circuit is complete (i.e., has low resistance or is "continuous") or if there is a break in the circuit (i.e., high resistance or "no continuity"). It's often used to check for broken wires or connections.
Capacitance (Farads - F): Some multimeters can measure capacitance, which is the ability of a component to store electrical energy in an electric field. It's often used to test capacitors.
Frequency (Hertz - Hz): Some multimeters can measure the frequency of an AC signal, indicating the number of cycles per second.
Temperature (Celsius - Fahrenheit): Certain multimeters are equipped with a temperature sensor and can measure temperature in degrees Celsius or Fahrenheit.
Diode Testing: Multimeters can test diodes to determine if they are functioning correctly by measuring the forward voltage drop.
Multimeters are versatile tools used by electricians, engineers, and hobbyists to troubleshoot electrical circuits, diagnose faults, verify component values, and ensure proper operation of electrical devices and systems. It's important to set the multimeter to the correct range and mode for accurate measurements and to follow safety precautions while using it.

User questions & answers
Question: | Is the unit truly auto-ranging? i see a "range" button on the unit pictured |
Answer: | Yes |
Question: | What batteries does it use |
Answer: | 9v battery. It does come with it. You will have to install. |
Question: | For a hobbyist, why would I not buy a $20 multimeter vs something |
Answer: | Fora hobbyist the really cheap meters are the best because sooner or later one will test something that will ruin the meter. This meter is really an intermediate meter which is above the hobbyist stage but still below the professional stage. An no, buying a Krug doesn't make you a professional. |
Question: | Does continuity test produce a beep |
Answer: | Yes. Turn dial to diode setting and press FUNC once. Beep is plenty loud. Great meter for the price. |
