Manual for VMP300-based instruments

13. Glossary

This glossary is made for the user to understand most of the terms used in this instrument
installation and configuration manual. The terms are classified in the alphabetical order.
Amplifier: current power booster that can be added to each channel individually.
Bandwidth: It depends on the electrochemical cell impedance. The bandwidths values are
going from 1 to 9. Bandwidth selection is important for the stability of the potentiostat during
measurement.
Calibration: operation that has to be done for each channel in order to reduce the difference
between a controlled value (for example E ) and the corresponding measured value (for
ctrl
example E ).
we
Cell connection: connection of the instrument channel board to the electrochemical cell with
five leads.
Mixed DB-25: connector with 25 pins on the instrument front panel where the cable connecting
the channel board and the electrochemical cell is set.
DB-9: connector with 9 pins on the instrument front panel used as auxiliary input/output.
DB-15: connector with 15 pins on the instrument front panel used to connect the channel board
to the booster or to the calibration board.
Default settings: settings defined and saved as default by the user and automatically opened
when the corresponding protocol is selected.
Firmware upgrading: the firmware is the operating system of the instrument. With new
improvements on the instrument, it is necessary to upgrade the firmware and the software to
benefit of the most recent version.
Gateway: IP address allowing the connection of computers from different networks onto an
instrument.
Impedance: defined by the ratio E/I.
Low current: option providing a sub-aA resolution that can be added to each channel by the
mean of a cable with an electrometer. This option extends the current range down to 1 pA with
gain. This option can be added both to standard or Z option channel boards.
Network: group of computers connected together in which the multichannel potentiostat can
be added. Several users with different computers can lead experiments in one or more
channels of the potentiostat.
Specifications: Characteristics of the instrument such as cell control or current and potential
measurement.
Subnet mask: IP number used when the instrument is not in the same network as the
computer.
