AC voltmeter & nbsp; V3-63 span> & nbsp; span> designed for measuring the RMS value of the AC voltage sine wave. It is used as a working and exemplary measuring device for checking and calibration of electronic voltmeters, signal generators and calibrators on the level of the output voltage span> p>
In addition to direct measurement of the voltage in the device V3-63 includes modes:. Determining the relative deviation (in percentage and dB) of the measured voltage from the prescribed level; & nbsp;
automatic calibration and zero setting, the device self-diagnosis and work capacity of constituents p>
& nbsp;. p>
Main specifications & nbsp; voltmeter V3-63: strong> p>
range of measured voltages: 10 mV - 100 V.
izmreniya range given by the relative difference between the measured nominal voltage: -20 ... + 20% p>
