A voltmeter is an instrument used for measuring electric potential difference between two points in an electric circuit. It is connected in parallel. It usually has a high resistance so that it takes negligible current from the circuit. Digital voltmeters give a numerical display of voltage by use of an analog-to-digital converter. A digital voltmeter measures an unknown input voltage by converting the voltage to a digital value and then displays the voltage in numeric form. ALIND make digital three phase voltmeter comes with Micro-controller Based Design suitable for all panels. It can be used to used to measure and monitor 3 phase voltages in corresponding networks. It has got a 4 digit bright LED Display for better visual indication for the operator/user. Its highly durable and protected design helps to operate on wide range of power supplies. The ratios between the primary and secondary rated voltages are programmable. Accurate and continuous measurement of True RMS value is made possible with the digital voltmeter. Password protection feature is also available for prevention of operations by unauthorized personnel.
