IR (Insulation resistance)?

When I measure the IR of a capacitor with IR meter. First I need to charge the capacitor, normally with its rated voltage, charge the capacitor for a certain time. When I use higher charging voltage, the IR measured is also getting higher. Why?

Answer:

I'm not sure an IR meter is the optimal way for testing capacitors? But, if you do this, I would suggest that the capacitor only be tested at its rated voltage. And, a meaningful measurement may only be obtained if you use a known good reference capacitor for comparison.
I expect, measurement values will vary between capacitor types, i.e. disc, ceramic, vs. electrolytic, tantalum, etc. So, I expect a good known reference is needed to make a valid assessment.
