Abstract
The present disclosure relates to a hand-held voltmeter measuring a peak voltage of a high voltage pulse applied to an electric fence. The voltmeter includes a body case of which one side has an opening, a sensor case protruded from the opening of the body case, a voltage divider disposed over the inside and the outside of the sensor case for dividing the high voltage pulse into a low divided voltage, a peak detector for detecting the peak voltage of the divided voltage, a display unit for displaying the peak voltage, and an MCU for controlling the input and the output of the elements constituting the voltmeter. According to the present disclosure, an electric fence voltmeter that measures the peak voltage accurately without need to make a ground connection to the earth, and has a low risk of an electric shock during a measurement is provided.
