| Zusammenfassung: | A refit high voltage voltmeter comprises a voltmeter, a first resistor, a second resistor, a safety, a toggle switch and a diode. The safety, the first resistor, the second resistor, the voltmeter and the safety are sequentially and adjacently in series connection. The second resistor is connected with an anode of the voltmeter. A cathode of the voltmeter is connected with an anode of the diode. A first fixed contact of the toggle switch is connected between the safety and the first resistor. A second fixed contact of the toggle switch is connected between the first resistor and the second resistor. A moving contact of the toggle switch is connected between the second resistor and the voltmeter. The refit high voltage voltmeter of the utility model is safe and reliable and is low in cost. |
