Working specifications
Resistance (R)
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)
Buzzer
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
Auto Power Off function shutting down the device after a certain inactivity time.
Display Backlight
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.
USB interface
The USB interface allows the device to be connected to other devices and thus enables the exchange of data and values of the measured quantities.
Average value
AVG function shows the average of the measurements.
Data Logging
This feature allows you to store measurement data in your device.
Frequency
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.
