1．测试注意事项

a．本仪器应水平安放；

b．如果你需要较精确地测量，请接通电源后，预热30分钟；

c．调节主调电容或主调电容数码开关时，当接近谐振点时请缓调；

d．被测件和测试电路接线柱间的接线应尽量短，足够粗，并应接触良好、可靠，以减少因接线的电阻和分布参数所带来的测量误差；

e．被测件不要直接搁在面板顶部，离顶部一公分以上，必要时可用低损耗的绝缘材料如聚苯乙烯等做成的衬垫物衬垫；

f．手不得靠近试件，以免人体感应影响造成测量误差，有屏蔽的试件，屏蔽罩应连接在低电位端的接线柱。

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.
