3.2 Abbreviations
Delete, from the existing list, the abbreviation "RTF" and associated term "Reference transfer
factor".
4.3 The absorbing clamp assembly calibration methods and their relations
Replace, in the existing second paragraph, the two occurrences of the word “three” by the
word “two”.
Replace, in the last sentence of the existing fourth paragraph, the word “three” by the word
“two”.
Delete the entire item c) (entitled “The reference device method”) and all corresponding text,
including Equations (9) and (10).
Replace, in the paragraph immediately following the existing item c), the two occurrences of
the word “three” by the word “two”.
Delete, in the fourth paragraph following the existing item c), the last sentence “Similarly, the
reference transfer factor RTF is determined by” and corresponding Equation (12).
Delete the entire paragraph immediately following Equation (12).
Replace, in the last paragraph of this subclause, the second sentence by the following new
sentence:
The jig method gives the CF , from which the original absorbing clamp factor can be
jig
calculated using Equation (11).
Add, at the end of this subclause, the following new paragraph:
Absorbing clamps with different geometries, different arrangement and material of ferrites,
different current probes as well as different housing material do require a separate
determination of the JTF. A new determination is also required if a different type of jig is used,
e.g. larger geometry.
4.5.3 Requirements for the ACTS
Add, after the first sentence of item e), the following new text:
It is also permissible to use clamp factors provided on a calibration certificate by a calibration
laboratory. However, such clamp factors that are used as a reference for an ACTS validation
shall be determined only using the original calibration method.

4.6.1 Overview
Delete, in the second paragraph, the phrases “and the reference device calibration method”
as well as “and the reference device clamp factor”.

Figure 1 − Overview of the absorbing clamp measurement method and the associated
calibration and validation procedures
In the figure, delete the entire item d).

Table 1 − Overview of the characteristics of the three-clamp calibration methods and
their relation
In the title, replace the phrase “three-clamp” by the new phrase “two clamp”.
In the table, delete the entire third row (the row having the name “The reference device
method”).
Figure 3 – Schematic overview of the clamp calibration methods
Delete Figure 3d.
Delete, from the key in this figure, the symbol “CF ”
ref
In the note, delete "and 3d", and replace the word “three” by the new word “two”.

B.2 Calibration methods of the absorbing clamp assembly
Replace, in the first sentence of the first paragraph, the words “For all three” by the new word
“Both”.
B.2.1.1 Calibration set-up and equipment
Replace, in the first sentence of the second dashed item, the phrase “larger than” by the new
word “of”.
Add, after the second sentence of the third dashed point, the following new sentence:
For practical reasons it is recommended to use a flexible lead under test.
Add, after the dashed list, the following new note:
NOTE A good match with the requirement of 4 mm diameter can be achieved by using the outer screen of a
coaxial cable (for example RG-58).

B.2.1.2 Calibration procedure
Add, after the second sentence of the third paragraph, the following new third sentence:
The receiver cable shall be suspended such that it is always spaced at a minimum of 200 mm
from the horizontal ground plane throughout the entire calibration process.

© IEC 2016
B.2.2.2 Calibration procedure
Add, after the last sentence of the fourth paragraph, the following new sentence:
The receiver cable shall be treated with a SAD. The SAD shall be positioned as shown in
Figures B.3 and B.4.
B.2.3 The reference device calibration method
Delete this entire subclause.
B.2.4 Measurement uncertainty of the absorbing clamp calibration
Add, immediately after the second bulleted list (pertaining to the jig calibration method) the
following new note:
NOTE It is assumed that the measurement instrumentation uncertainty of the required correlation process with the
original calibration method is sufficiently small such that there is no appreciable contribution to the uncertainty of
the jig calibration method.
Delete the entire third dashed list (“The reference device calibration method”).
Replace the last paragraph of this subclause by the following new paragraph:
Detailed guidance on the treatment of the measurement instrumentation uncertainty for
disturbance power measurements is given in CISPR 16-4-2.

Figure B.3 − Side view of the calibration jig
Replace the existing Figure B.3 by the following new figure:
