The equipment we have in our lab only provides a single polarity,
positive with respect to ground when in DC mode, which requires us to
manually reverse the leads to perform the test. We would like to
automate this without requiring the operator to manipulate the test leads.
We also do not want an operator to be involved in reversing the leads
if we need to perform this as a routine test in manufacturing
You could use a reversing switch (DPDT, cross-connected) if you can find
one with a high enough voltage rating.
