1．測試注意事項

a．本儀器應水平安放；

b．如果你需要較精確地測量，請接通電源后，預熱30分鐘；

c．調(diào)節(jié)主調(diào)電容或主調(diào)電容數(shù)碼開關(guān)時，當接近諧振點時請緩調(diào)；

d．被測件和測試電路接線柱間的接線應盡量短，足夠粗，并應接觸良好、可靠，以減少因接線的電阻和分布參數(shù)所帶來的測量誤差；

e．被測件不要直接擱在面板頂部，離頂部一公分以上，必要時可用低損耗的絕緣材料如聚苯乙烯等做成的襯墊物襯墊；

f．手不得靠近試件，以免人體感應影響造成測量誤差，有屏蔽的試件，屏蔽罩應連接在低電位端的接線柱。

Using method
High frequency Q table is multi-purpose impedance measurement instrument, in order to improve the measurement accuracy, in addition to the Q table test loop itself residual parameters as much as possible, so that the frequency response of the coupling loop is as good as possible, but also master the correct test method and residual parameter correction method.
1 test note
A. the instrument should be placed horizontally;
B. If you need a more accurate measurement, please put on the power supply, preheat 30 minutes;
C. regulates the main capacitor or main capacitor digital switch, when close to the resonant point please slow tune;
The D. is the connection between the test piece and the test circuit wiring should be as short as possible, thick enough, and should be in contact with good, reliable, in order to reduce the resistance and the distribution parameters caused by the measurement error;
E. is not directly placed on the top of the panel, the top of the top of a centimeter above, when necessary, the use of low loss of insulation materials such as polystyrene, etc.;
F. hand shall not be close to the test piece, lest the human body sensor affect the measurement error, and there is a shield of the test piece, and the shield cover should be connected to the terminal of the low potential.
