This module is a combination (of the PCBoards) of 3 modules:S3b,M1h,M0.
All specs can be found at the infopages of these modules. Difference with VIa is M1h (fast/low-Rin IV-converter)
Although specs are the same, because of limited frontpanel space some functions are skipped and the Lemo-connectors are replaced by the smaller MCX connectors (see picture).
Functional differences for the Imeas compared to M1h:
The ground/float switch is skipped, you do not loose functionality, the mcx labelled "gnd/ref" can be connected to either ground or a reference voltage (allowing groundlift).
The 2 switches "lowRin/LowNoise" and "postgain" have been combined in one
You loose some combination settings
now you get: x100ac with low noise/low Rin with x1/low noise with x1
