10-bit A/C Converter is adopted. High resolution provides extremely precise testing.
Improved basic performances of impulse tester (such as signal-to-noise ratio, frequency characteristic, etc.) enabled more detailed Partial Discharge noise detection.
Base line fluctuation of AC or DC coupling due to the temperature change is controlled by the auto zero adjustment; as a result, precision of PASS/FAIL detection has improved. The auto zero adjustment is essential for materializing 10-bit voltage resolution tester.
