1, high precision
Using precision high-voltage film capacitors and precision high-voltage glass glaze resistance, the input impedance is high, the test current is reduced, the power consumption is small, and the measurement accuracy and stability of the instrument are improved; the signal processing part uses high-performance OP for signal amplification and uses the latest double Integral AD sampling technology, four-and-a-half-digit liquid crystal display, with a maximum resolution of 0.001kV, is an updated product of high-voltage electrostatic voltmeter.
2, good anti-interference performance
Using special shielding technology. The surface of the pressure equalizing ball of aluminum alloy material is smooth and shiny, which effectively improves the electric field distribution around the equalizing ball, prevents sharp discharges, and improves the anti-interference ability of the measurement data. The low-voltage display instrument adopts all-metal enclosed structure shielding, and the high-voltage divider and the low-voltage display meter are connected by high-quality coaxial cables to reduce the influence of high voltage on the indication value, thereby achieving high stability and high linearity.
3, safe and reliable
This instrument is composed of a high-voltage divider and a low-voltage display instrument. The high-voltage divider is filled with American DuPont filling materials, and is potted with a special process. The structure is smaller, the weight is lighter, the internal partial discharge is minimized, and the reliability is higher. There is no oil leakage problem. When working, the high-voltage divider and low-voltage instrument are connected by coaxial cables, and the high and low voltage parts are far apart, so the work is safe and reliable.
4, simple operation
Adopt dial switch to switch between high and low voltage, AC and DC, which is convenient and quick. Four and a half LCDs directly display the measurement results, which is simple and intuitive. Bring great convenience to on-site inspection work.
5. Easy to carry
Using a portable structure, the whole machine uses an aluminum alloy packing box as the casing, which can be easily disassembled and assembled. Small size, light weight, easy to carry, and very convenient to use.
