Parameters/Characteristics
To obtain IR limit, divide MΩ-µF value by the capacitance and compare to GΩ limit. Select the lower of the two limits.
Capacitance and Dissipation Factor (DF) measured under the following conditions:
1MHz ± 100kHz and 1.0Vrms ± 0.2V if capacitance ≤1000pF
1kHz ± 50Hz and 1.0Vrms ± 0.2V if capacitance >1000pF
Note: When measuring capacitance it is important to ensure the set voltage level is held constant. The HP4284 & Agilent E4980 have a feature known as Automatic
Level Control (ALC). The ALC feature should be switched to "ON".
