1, high precision
Using precision high-voltage film capacitor and precision high-voltage glass glaze resistance, the input impedance is high, the test current is reduced, the power consumption is small, and the measuring accuracy and stability of the instrument are improved.
Signal processing part, the use of high-performance OP signal amplification, the use of double integral AD sampling technology, four half liquid crystal display, high resolution up to 0.001kV, is the replacement of high-voltage electrostatic voltmeter products.
2, good anti-interference performance
Special shielding technology is used. The surface of the aluminum alloy pressure ball is smooth and bright, which effectively improves the electric field distribution around the pressure ball, prevents the tip discharge, and improves the anti-interference ability of the measurement data. Low voltage display instrument adopts full metal closed structure shielding, high voltage divider and low voltage display meter adopts high quality coaxial cable connection, reducing the influence of high voltage on the display value, so as to achieve high stability and high linearity.
3, safe and reliable
The instrument is composed of high voltage divider and low pressure display instrument, high voltage divider using DuPont filling material, special process pot-sealing, smaller structure, lighter weight, internal local discharge to the lowest, higher reliability. There is no oil spill problem. The high voltage divider and low voltage instrument are connected by coaxial cable, and the distance between the high and low parts is far away, and the work is safe and reliable.
4. Simple operation
Use dip switch to switch high and low voltage, AC and DC, convenient and fast. The four-digit semi-liquid crystal displays the measurement results directly, which is simple and intuitive. Bring convenience to the on-site inspection work.
5, easy to carry
With portable structure, the whole machine is made of aluminum alloy packing case, which can be easily disassembled and assembled. Small size, light weight, easy to carry, very convenient to use.
