The Mastech MS830D is an innovative multimeter with Smart feature that benefits from the services so it can be used easily and comfortably without any knowledge of electronics and electrical engineering. This compact multimeter automatically detects AC / DC voltage, resistivity and continuity by visualizing the measured values of a large dual display. This is an ideal tool for home-made craftsmen, amateurs and electricians

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)
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".
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.
Duty cycle is the proportion of time during which a component, device, or system is operated. The duty cycle can be expressed as a ratio or as a percentage. Suppose a disk drive operates for 1 second, then is shut off for 99 seconds, then is run for 1 second again, and so on. The drive runs for one out of 100 seconds or 1/100 of the time, and its duty cycle is therefore 1/100, or 1 percent.
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.
Non contact voltage, NCV tester is a useful tool for any kind of electrical work - there is no quicker or simpler way to safely check for electrical current in a wire, outlet, switch or an old lamp that has mysteriously stopped working.
Automatic detection and visualization of dimensions such as: AC / DC voltage, resistance, continuity, etc.
