, humidity: ≤80% R.H;
Preheat the instrument for at least 30 minutes before the test;
Test at the test notch on the end face of the instrument;
It is better to conduct open and short circuit correction before the
test;
Measure with the recommended equivalent mode;
The percentage in terms of error indicates:
± (% of the r last digit)
If the actual measurement of the instrument and the display exceeds
the scope specified in the table, the accuracy of the excessive part
will not be given;
The meaning of the subscript
S- series equivalent; p- parallel equivalent; e- accuracy
Some parameters cannot be given in the data table, and it can only be
calculated based on the measurement results;
8.3.1. Accuracy indicator 1(ET433)
When the test level is 0.6V, the measurement accuracy by using Kelvin test fixture is
as follows:
