功率钳会从电源线开始的地方,不断移动,一直移动到6m长的位置。

这个0.6m没有明确的解释,但是我根据功率钳的机械结构来看,应该是功率钳的长度,下面是功率钳的尺寸图片。

6.3.2 Measurement procedure 测量程序

6.3.2.1 Measurement of the disturbance power is made firstly on the mains lead of the main appliance using the absorbing clamp in accordance with 6.2. Any lead connecting the main appliance to an auxiliary apparatus is disconnected if this does not affect the operation of the appliance, or is isolated by means of ferrite rings (or an absorbing clamp) close to the appliance.
首先,在器具主体电源引线上按6.2用吸收钳进行骚扰功率的测量。如果不影响器具的运行,连接器具主体到辅助装置上的任何引线都应断开,或者通过靠近器具的铁氧体环(或吸收钳)隔离。

6.3.2.2 Secondly, a similar measurement is made on each lead which is or may be connected to an auxiliary apparatus, whether or not it is necessary for the operation of the appliance; the current transformer of the clamp pointing towards the main appliance. Isolation, or disconnection of the mains lead and other leads is made in accordance with 6.3.2.1.
其次,在接到或可能接到辅助装置的每根引线上进行类似的测量,而无论器具运行时是否需要该引线;吸收钳的电流互感器指向器具主体。电源引线和其他引线的隔离或断开按6.3.2.1进行。
NOTE For short, permanently connected leads the movement of the clamp (as described in 6.2.3) is limited by the length of the lead.
注:对于短的、永久地连接的引线,吸收钳的移动受引线长度的限制(如6.2.3所述)

6.3.2.3 In addition, measurement is made as above but with the current transformer of the clamp pointing towards any auxiliary apparatus, unless this auxiliary apparatus is not needed for the operation of the main appliance and a separate test procedure for it is specified elsewhere (no disconnection or r.f. isolation of other leads is of course necessary in this case).
此外,测量仍按上述方法进行,但吸收钳的电流互感器指向任一辅助装置,除非辅助装置是器具主体运行所不需要的而且另外规定有单独的试验程序(当然,在此情况下其他引线不必断开或射频隔离)。

6.4 Assessment of measuring results
The measured power is derived from the maximum indicated value found at each frequency of measurement and the calibration curve of the absorbing clamp (see also the example given in Annex B of CISPR 16-1-3).
测量结果的评定
骚扰功率的测量值是在每个测量频率点找到最大指示值和吸收钳的校准曲线得出。(见CISPR16-1-3附录B中给出的例子)。
