Notes:
Environment temperature: 20
℃
± 2
℃
, humidity: ≤75% 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 reading + 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
