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)
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.
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".
Diode
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.
Autoranging
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. 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.
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.
Duty Cycle
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.
Low Battery
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
Data hold function is useful when measurements occur. So when pressing the "HOLD" button you will hold the display information.
Temperature (°F/°C)
Temperature measurement is done in degrees (°). The unit of measurement adopted by SI is Celsius (° C), but it can also be measured in Fahrenheit (° F). The freezing point of 0 °C = 32 °F and the boiling point 100 °C = 212 °F.
MAX/MIN
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.
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.
Ralative Measurement
Function to display a relative measurement value.
TRMS
True Root Mean Square
Peak Value
The "PEAK" function enables the instrument to measure peak values.
RS232 Interface
The device has a communication RS232 interface.
Clamp current
The device has clamps for non-contact measurement of values.
Low Pass Filter
Low pass filter
