INDOTECH DIGITAL VOLTMETER AC
Indotech Digital Voltmeter AC – The Indotech Digital Voltmeter is an instrument which can give the output voltage not by deflection but directly indicating the value. It is a very good instrument to measure the voltage as it eliminates completely the error due to parallax, approximation in measurement, high-speed reading can be done and it can also be stored in memory for further analysis. The main principle is that the value is measured by the same circuit arrangement but that value is not used to deflect the pointer, but it is fed to the analog to digital converter and displayed as the digital value..
Indotech Digital Voltmeter AC use solid-state components and display values digitally. Typically, digital voltmeters (digital volt meters) can be used to locate excessive resistance that may indicate an open circuit or ground. They are also used to identify low voltage or voltage drops that may indicate a poor connection. The positive lead is connected to the circuits positive side and the negative lead is connected to the circuits ground. The digital voltmeters internal resistance is the impedance, which is usually expressed in ohms per volt. This amount is relatively high in order to prevent the device from drawing significant current and disturbing the operation of the circuit being tested. The sensitivity of the voltmeter determines the range of voltages that digital voltmeters can measure.
TYPE OF METERS : Digital Voltmeter AC
Digital Voltmeter can measure levels of alternating current (AC) and direct current (DC). Some devices that measure AC current also measure root mean square (RMS) power, which is the square root of the time average of the square of the instantaneous power. Many digital ammeters include a current sensor built into the meter or that clamps around the wire. Different types of Digital Voltmeter can measure different ranges of AC current, DC current, and AC current frequency.
