(5 ±1 seconds and charge/discharge not exceeding 50 mA)
10% (6.3 and 10 V), 7% (16 and 25 V) and 5% (50 V)
See Insulation Resistance Limit Table
(Rated voltage applied for 120 ±5 seconds @ 25°C)
Parameters/Characteristics
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
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."
