Overview
YXY-30 three-phase multi-functional AC / DC voltmeter is a new intelligent instrument specially designed to meet the requirements of high voltage test. It has a touch screen display with bright color, full Chinese menu and operation tips, which can realize friendly man-machine dialogue. The instrument can be used to accurately measure AC voltage frequency, RMS, peak value, third and fifth harmonic components and average value of DC voltage.
YXY-30 three-phase multi-functional AC / DC voltmeter is convenient to use and can ensure measurement accuracy. With the use of high-voltage voltage divider or voltage transformer, it can directly display the actual test voltage value on the LCD screen, and the partial voltage ratio can expand the range according to the parameters of the external voltage divider within the measurement range. The power supply of the instrument is processed by the internal isolation filter circuit to ensure the safety of the instrument, so as to prevent the instrument from being damaged due to abnormal high-voltage test process. The instrument is equipped with 1 power line and 3 measuring lines (10m each).
