Figure 2-3 shows the configuration of the supplied charge filter. The purpose of
the filter is to minimize the effects of rapid voltage calibrator rise times that
would otherwise affect charge measurements.
To use the charge filter, connect the OUTPUT jack to the 1nF or lOOoF BNC jack
of the Model 5156, and connect the INPUT jack to the DC voltage calibrator
using a suitable BNC cable. Note that the charge filter should he used only for
