This module pretty much defines how accurate the whole system is — it holds the voltage reference and the resistance reference. It can be removed — the manual describes advises that you can interchange these modules between systems and it is practical really — you can send your calibration module to the lab and keep the device running.

The module can be adjusted slightly by these trimpots. Precise and fun stuff. A big red resistor?

These are then connected via flying cables with the rest of the 3455w. Also note that the resistance reference was connected to the rest of the system not like the voltage — on the board — but rather through a special plastic connector so that no gunk or crap may cause leakage and measurement errors.
