The volt box is likely to be a voltage divider that was used to divide a
voltage to be measured down to a value within the measurement range of a L & N
potentiometer (not the 3 terminal component but the type that sets up the
current in a series string of resistors to a known vale by comparing
Hello Dave.
So far I have identified 3 different Leeds & Northrup "Boxes".
Originally my intention was to re-purpose the box, panel connectors and
switch for a project to make my own precision resistor banks.
All use different switches and vastly different resistors to achieve
their original

I must admit I don't know what the purpose of the original unit is. Perhaps
as part of a bridge given the

No environmental chamber yet, have a Yokogawa controller and and an EIS
sensor simulator, going with a small box in the first for individual
components, but workload keeping me from completion of so many fun
projects. Now

Much appreciated! I saw some of those units listed on eBay inexpensively and
was curious about such a “mod”. Have you characterized it for tempco?
