Accuracy is ± ( % of reading＋number of digits ).
Cx is capacitance readout in counts.
Accuracy is applied when C is from 20 to 100% of full scale range in series
mode measurements.

Electrical Specifications
The test leads should be as short as possible to
minimize the measurement error.
For best accuracy, zero adjustment should be
performed appropriately before testing.
