Nickname: High Voltage Meter; voltage divider; digital voltage meter
Feature:
1. High precision
Adopt precision high-voltage film capacitors and precision glass glaze resistors, high input impedance, reducing the test current, low power consumption, improve the instrument's measurement precision and stability;
Signal processing part, using high-performance OP to amplify signal, using the latest technology dual integral AD sampling, four semi-liquid crystal displays, the highest resolution reaches 0.001kV, it is the upgrading production of static high voltage meter.
2. Good anti-jamming performance
Adopt special shielding technology. The surface of equalizing ring is smooth and glossy, effectively improve the electric field distribution around the equalizing ring to prevent point discharge, improve the anti-jamming capability of measurement data. The voltmeter adopts all-metal enclosed structure shielding, using high quality coaxial cable connect HV divider with the voltmeter, reduce the impact of HV on the indication values, so as to achieve high stability, high linearity.
3. Safe and reliable
The instrument is composed of high-voltage divider and voltmeter, high voltage divider using DuPont filling materials, special casting process, smaller in structure, lighter in weight, to minimize internal partial discharge, higher reliability. There is no leakage problem. When working, use high quality coaxial cable connect HV divider with the voltmeter, safe and reliable.
4. Simple operation
Adopt DIP switch to switch high voltage and low voltage, AC and DC, convenient and quick. Four semi-liquid display direct shows measurement result, simple and intuitive. It is convenient for on-site testing work.
5. Easy to carry
Use portable structure, the whole chassis with aluminum box can be easily dismounted. Small in size, light in weight, easy to carry, easy to use.
