1、试验电压：不了解试品阻抗的情况下可以先用 2V试测，如果试验电流小于 1A可以改用 25V测量。

1, test voltage: if the impedance of the test product is not understood, it can be tested by 2V first. If the test current is less than 1A, it can be measured by 25V.

2、电流检测：钳形 CT夹到需要测量电流的部位。例如可以夹到连接电容的引线上而不一定是电容的套管。如果是测量总电流，也可以直接夹到电压引线上。

2、电流检测：钳形 CT夹到需要测量电流的部位。 For example, a sleeve that can be clamped to a connecting capacitor is not necessarily a capacitor. If the total current is measured, it can also be directly clamped to the voltage lead.

3、钳形 CT朝向：要求将电流钳的正面朝向红夹子（即 2V或20V）方向，此时仪器自动区分电容、电感或者电阻。

The 3 clamp CT: positive clamp toward the red clip (2V or 20V), then the instrument automatically distinguish between the capacitance, inductance or resistance.

4、磁场干扰：建议钳型 CT远离仪器 1米以上。如果测量一个漏磁严重的电感，建议远离电感 1米以上。

4, magnetic field interference: it is suggested that the forceps CT is far away from the instrument more than 1 meters. If a magnetic flux leakage inductor is measured, it is suggested that the inductance be far away from the inductance of more than 1 meters.

5、低电感（感抗）和大电容：夹子应尽量靠近试品引出线端子。

5, low inductance (inductance) and large capacitance: the clip should be as close as possible to test lead wire terminal.

6、测量过程：接线完毕启动测量电源。测量过程中，不要移动电压线，不要触摸或移动钳型 CT。

6, measurement process: the connection is completed to start the measurement of the power supply. In the process of measurement, do not move the voltage line, do not touch or move the tongs type CT.
