| Kleinstein:
The measurement frequency can make quite a difference, as the input can have some resistance (and maybe inductance) from the protection in front of the main input capacitance. With a high test frequency the resistance can hide the capacitance, especially if large. With a low frequency series resistance is less relevant. For the use of the DMM the additional resistance can also make a difference: it can be enough that loading an OP-amp is no longer an issue. |
