millisKanner rather than the milliK. This means that the voltage measurement uncertainty
is the same whether measurements are made directly on the milliK or via a millisKanner.

One of the most common sources of failure in instruments of this complexity is the
contacts in switches, relays, connectors and potentiometers. For this reason, the
millisKanner was designed to have no switches, mechanical relays, internal connectors or
potentiometers in order to ensure optimum reliability.
Conventional instruments of this type use mechanical relays for some or all of the signal
routing. The millisKanner uses only solid-state switching. The thermal EMFs from these
solid-state devices are significantly less than even the best mechanical relays. As a
result, the millisKanner achieves voltage offsets significantly less than 2\V.
