Voltage(symbol: V), also called electromotive force, is a quantitative expression of the potential difference in charge between two points in an electrical field.
Current ( I )
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 ( C )
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".
A diode is a specialized electronic component with two electrodes called the anode and the cathode. Most diodes are made with semiconductor materials such as silicon, germanium, or selenium. The fundamental property of a diode is its tendency to conduct electric current in only one direction. When the cathode is negatively charged relative to the anode at a voltage greater than a certain minimum called forward breakover, then current flows through the diode. If the cathode is positive with respect to the anode, is at the same voltage as the anode, or is negative by an amount less than the forward breakover voltage, then the diode does not conduct current. This is a simplistic view, but is true for diodes operating as rectifiers, switches, and limiters. The forward breakover voltage is approximately six tenths of a volt (0.6 V) for silicon devices, 0.3 V for germanium devices, and 1 V for selenium devices.
Automatic switching of a multirange meter from its lowest to the next higher range, with the switching process repeated until a range is reached for which the full-scale value is not exceeded.

Auto Power Off
Auto Power Off function shutting down the device after a certain inactivity time.
Rear screen illumination is an important advantage for any device that owns it. Thanks to it, the visibility and legibility of the screen is increased, thus the device is much more subtle and reliable in small ambient light and long-term use.
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.
Press the MAX/MIN key to show the maxinum reading value among measuring data, and the “MAX”symbol appears on the display. Press the button again, the “MIN” symbol appears on the display and will show the minimum reading value among measuring data, press the button again to return to normal mode.
A feature that enables the device to measure a Inrush Current.
Integrated work light, which provides extra convenience when working in environments with insufficient ambient light.
True Root Mean Square
Frequency describes the number of crests of a wave that move past a given point in a given unit of time. The most common unit of frequency is the hertz (Hz ), corresponding to one crest per second. The frequency of a wave can be calculated by dividing the speed of the wave by the wavelength.So if the time it takes for a wave to pass is is 1/2 second, the frequency is 2 per second. If it takes 1/100 of an hour, the frequency is 100 per hour.
