1,Ionization charge based sampling technique significantly improves the accuracy of the vacuum interrupter vacuum measurement.
A built-in vacuum interrupter abroad almost all measurement curves tube can choose.
2, the leakage current treatment. Starting method using two high-pressure, less leakage current, ensure the accuracy of vacuum interrupter vacuum.
3, improve the input protection circuit. Instrument can accept a strong current impact, when faced with completely airtight tube, the instrument automatically identified.
1, range: 1 × 10-5 ~ 1 × 10-1Pa
2, the measurement error: 1 × 10-4 ~ 1 × 10-1Pa error of <10%
