介電常數(shù)高頻測試儀維修

1．新購儀器的檢查

新購的儀器能先用LKI-1電感組，將各個電感在各個不同頻率測試Q值，把測試的情況，例使用的電感號、測試頻率Q讀數(shù)、電容讀數(shù)等多次測得數(shù)及測試環(huán)境條件逐一詳細記錄，并把記錄保存起來，以供以后維修時作參考。

LKI-1電感組是測試時作輔助電感用的，不能把這些電感當作高精度的標準電感看待。隨著測試環(huán)境條件不同，測得電感器Q值和分布電容可能略有不同。

b．使儀器經(jīng)常保持清潔、干燥；

c．本儀器保用期為18個月，如發(fā)現(xiàn)機械故障或失去準確度，可以原封送回本廠，免費修理。
