Voltage(symbol: V), also called electromotive force, is a quantitative expression of the potential difference in charge between two points in an electrical field.

An electric current is a flow of electric charge. The common symbol for current is the uppercase letter I. The SI unit for measuring an electric current is the ampere(A), which is the flow of electric charge across a surface at the rate of one coulomb per second. The particles that carry the charge in an electric current are called charge carriers.

Resistance is the opposition that a substance offers to the flow of electric current. It is represented by the uppercase letter R. The standard unit of resistance is the ohm(Ω)

Capacitance is the ability of a component or circuit to collect and store energy in the form of an electrical charge. The SI unit of capacitance is the farad (symbol: F), named after the English physicist Michael Faraday. A farad capacitor, when charged with 1 coulomb of electrical charge, has a potential difference of 1 volt between its plates.

In electronics, a continuity test is the checking of an electric circuit to see if current flows . A continuity test is performed by placing a small voltage across the chosen path. If electron flow is inhibited by broken conductors, damaged components, or excessive resistance, the circuit is "open".

Auto Power Off function shutting down the device after a certain inactivity time.

The indication for low battery level is a useful feature and alert the user when needed battery unit to be changed. So you will still have a functioning device for use.

Data hold function is useful when measurements occur. So when pressing the "HOLD" button you will hold the display information.

Transistor-check function. hFE of a transistor is the current gain or amplification factor of a transistor.

Temperature measurement is done in degrees (°). The unit of measurement adopted by the SI system is Celsius (° C), the freezing point of water is 0 ° C and the boiling point is 100 ° C.

An inductor , also called a coil or reactor, is a passive two-terminal electrical component that stores electrical energy in a magnetic field when electric current is flowing through it. An inductor typically consists of an electric conductor, such as a wire, that is wound into a coil. When the current flowing through an inductor changes, the time-varying magnetic field induces a voltage in the conductor, described by Faraday's law of induction. In the SI, the unit of inductance is the henry (H). Inductors have values that typically range from 1 µH (10−6H) to 1 H.
