Impedance Measurement Accuracy
I Z I - 6 Measurement Accuracy:
I Z ! Accuracy; ±[(% of reading) + (number of counts)], see Tables C-l and C-2.
0 Accuracy: ±[( 6 error in degrees) + (number of counts)], see Tables C-l and C-2.
Note:
Use Table C-l when the test frequency is lOkHz, lOOkHz, or IMHz.
Use Table C-2 for all other frequencies.
Note:
Accuracies obtained from Tables C-l and C-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 C-3 to the accuracies obtained from Tables C-l and C-2.
