Embodiment Construction
[0010] Such as figure 1 As shown, the present invention adopts every two voltmeters in series to form at least three groups, a total of 6 voltmeters A 1 ~A 6 , the voltmeters are all digital display DC voltmeters, the series contacts of each two voltmeters respectively lead to an external measurement terminal 2, 3, 4, and the positive connection contacts of the voltmeters in series lead to an external measurement terminal 1, and the negative connection The contact leads to an external measuring terminal 5, which is the first group of voltmeters A 1 The negative terminal of the voltage input and the voltmeter A 2 The positive end of the voltage input is connected to the contact and leads to an external measuring end 2. The second group of voltmeters A 3 The voltage input negative terminal of the voltmeter A4 is connected with the voltage input positive terminal of the voltmeter A4 to draw an external measuring terminal 3 . The third group of voltmeter A 5 The voltage inpu...
