See Insulation Resistance Limit Table
(Rated voltage applied for 120 ±5 seconds @ 25°C)
Regarding aging rate: Capacitance measurements (including tolerance) are indexed to a referee time of 1,000 hours.
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:
1 kHz ±50 Hz and 1.0 ±0.2 Vrms if capacitance ≤ 10 μF
120 Hz ±10 Hz and 0.5 ±0.1 Vrms if capacitance > 10 μF
Note: When measuring capacitance it is important to ensure the set voltage level is held constant. The HP4284 and Agilent E4980 have a feature known as
Automatic Level Control (ALC). The ALC feature should be switched to "ON."
