| N.S. | 1%+10+2000/Cx | 2%+20+2000/Cx | N.S. | |
| Note: | ||||
| *Accuracy is ¡À(% of the reading +number of reading) | ||||
| *Cx is capacitance readout in counts | ||||
| *Accuracy is applied when Cx is from 20% to 100% of full scale range in series mode only. | ||||
| * Since the meter may test a capacitor under different conditions than that we make in factory, the values might not be identical as we do in factory, this is not due to meter error,just the test mode and test conditon may vary in different measurement conditions. | ||||
