LC module

The Low Current module (LC module) adds 3 real current ranges below the existing current ranges of the Ivium potentiostat to which it is connected. These additional current ranges are available for potentiostatic measurements. It is an analog module and is compatible with almost all Ivium potentiostats, including the 24bit instruments.

The IviumStat and CompactStat have real current ranges down to 100pA full scale as standard (the 10pA and 1pA current ranges are gained ranges). When the LC module is connected, the 10pA, 1pA, and 100fA real current ranges are added.

All other instruments (excluding the pocketSTAT2.LC) have real current ranges down to 10nA (the 1nA and 100pA current ranges are gained ranges). When the LC module is connected, the 1nA, 100pA, and 10pA real current ranges are added.

The LC module connects between the potentiostat and the cell cable, and is powered from the cell cable (no additional power supply is required). As the LC module adds high sensitivity current ranges, it should always be used inside a Faraday cage.
