The unit is assembled in a clean-room environment and sealed together, after which it is assigned one single type number and one single serial number. This means that the combined unit has better precision and long-time stability, and is handled as one complete unit.
The unit also contains TEDS, which means that information about the serial number, type and sensitivity is stored within it.
