ZX-FRC-1.0 digital kilovoltmeter consists of a high stabilized resistive-capacitive type passive high-voltage divider and a precision digital voltmeter for measuring AC/DC high voltage on the site of electric power systems and in various high-voltage laboratories. Both of them with measuring cable, power supply cord, and operating manual are placed in a portable aluminium case for easy carrying and use.

Preparation Before Test (Measurement)

(1)High voltage divider is arranged in a proper position. Be sure that, an adequate clearance should be kept to surrounding objects. The minimum clearance should not be less than the height of the volgate divider.

(2)Grounding connection: The ground terminals of voltage divider basement and of digital voltmeter should be reliably connected to ground by braided copper wire.

(3)Measuring signal connection: The supplied coaxial measuring cable is specially prepared for connecting from voltage signal output socket of divider bacement to the signal input socket of digital voltmeter. If should not be replaced by other coaxial cable or any connecting wire, because of capacitive match to the voltage divider.

(4)High voltage connection: The high voltage terminal to be measured is connected to the top connecting screw MIO of voltage divider by HV leads. Be sure that, an adequate angle of 75°~90°between HV leads (inclined downward) and vertical axis of voltage divider should be kept during calibration and use for precise measurement.

Range Selector

Press the range selector to change the measuring range. In case of measured voltage less than 20kV, turn the range selector in lower range for higher measuring accuracy. When the measured voltage is higher than 20kV, turn the voltage selector in higher range.
