再說明一下：Sensitivity Requirements - At least once each year the sensitivity of the dielectric equipment is to be checked. The sensitivity of the equipment is to be such that when adjusted to produce the required test voltage and with a 120,000 ohm resistor across the test terminals, the equipment indicates a "breakdown" (a nonconforming performance indication by the tester) within 0.5 seconds. The resistor used shall be provided by the manufacturer and shall have a resistance found to be equal to or greater than 120,000 ohm when measured using a calibrated ohmmeter traceable to the National Institute of Standards and Technology (NIST). If the equipment does not meet this sensitivity test, it shall be readjusted and provision made to maintain the proper calibration.
靈敏度的要求-至少每年一次的介電設備的靈敏度進行檢查。該設備的靈敏度是這樣的，當調(diào)整以產(chǎn)生所要求的試驗電壓和一個120000歐姆的電阻在測試終端設備，表示“崩潰”（一個不合格的績效指標的測試）在0.5秒。電阻器必須由制造商提供的，必須有一個電阻的發(fā)現(xiàn)是等于或大于120000歐姆歐姆表測量時，使用校準可溯源到國家標準與技術研究所（NIST）。如果設備不符合這種敏感性試驗，應當調(diào)整，保持適當?shù)男试O置。 |
