SECTION I
Model 4277A
Table l-L Specifications (Sheet 9 of 17)
Inductance Measurement Accuracy
L-D Measurement Accuracy 5
L Accuracy:
±[(% of reading) + (L error) + (number of counts)], see Tables R-1 and
B-2.
D Accuracy:
±[(% of reading) + (D error) + (number of counts)], see Tables B-1 and
B-2.
Note:
Use Table B-1 when the test frequency is lOkHz, lOOkHz, or IMHz,
Use Tables B-2 for all other frequencies.
Note:
Accuracies obtained from Tables B-1 and B-2 are valid only for
measurements made with the CABLE LENGTH switch set to Om.
When the CABLE LENGTH switch is set to Im, add the errors listed
in Table B-3 to the accuracies obtained from Tables R-1 and B-2.
