.
Select a calculation method using the soft keys:
acc. to IEC 60044-1 (calculation exactly acc. to
standard), acc. to OMICRON (calculation considers CT
remanence) or acc. to GB 16847 (acc. to Chinese
standard GB 16847).
Default: As defined in the default test settings (see
"Default Standard" parameter in section 5.7.1 on
page 65).

1. If the question mark is entered for this parameter and a new test is started, the CT Analyzer
automatically tries to determine the value using its integrated guesser function (see chapter 7 on
page 131).
2. If the question mark is entered, half the voltage entered or measured for E
k
is used.
3. If the question mark is entered, the CT Analyzer uses the excitation current measured at the
voltage value defined at E
1
. In this case, the assessment for this parameter is OK.
