Param. Description
t-al2 * Permissible time to accuracy limit for second
energizing period of the duty cycle.
Note: Only displayed if parameter "Spec." is
"by Duty" and "Duty" is "CO-CO".
Possible values: 0.000 to 5.000s or soft key
40ms.
Default: ? or ?*.
* If displayed, this parameter is relevant for
assessment. No automatic assessment is
available if the user did not enter data for this
parameter prior to the test (see page 82).
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
3. If the question mark is entered, the CT Analyzer uses the excitation current measured at the
voltage value defined at E . In this case, the assessment for this parameter is OK.
