Micromanipulator users:
It appears as if the HP 4075 LCR meter is not functioning.  In particular, when pressing the "Test V" button, there is no evidence that is it producing the variable aplitude AC signal that is required to measure AC capacitance and/or impedance.
I've not yet had the time to investigate this more fully to know whether this is a straightforward or more serious problem.
