current ranges
A potentiostat measures current. For optimal precision, the range between which currents are measured is split into multiple current ranges. A current range defines the maximum current a potentiostat can measure in a certain range. This means it will also determine the resolution, because the number of bits or rather states is fixed, while the current range is variable.

1 nA to 10 mA (8 ranges) | 1 nA to 100 mA (9 ranges) |
| maximum current | ± 20 mA typical and ± 15 mA minimum |

The current is measured using a zero resistance ammeter (ZRA).

current accuracy (deviation)
The current accuracy describes how close to the real values your measured current is.

electrometer amplifier input
The amplifier input resistance of the amplifier in the electrometer determines the load that the amplifier places on the source of the signal being fed into it. Ideally the resistance is infinite, and the load to be zero to not to influence your measurement.
