Manual Instrumentation Control
Having precise manual control over instrumentation as is possible with a Manual ZRA or a Manual Potentiostat can be a useful tool in an educational environment Manual Instrumentation Control enables a computer controlled instrument to be manually controlled.
Begin by selecting the correct instrument serial number and click on the Open button.
ZRA
The Zero Resistance Ammeter section begins operating as soon as communication is opened to the instrument Over / Under range LED’s are provided as a guide for selecting the correct count resistor. A Show Trend button can be pressed to show a small trend graph of potential and current. Set to Rp sets the Value to the rest potential it should only be clicked when the instrument is Isolated from the cell.
Potentiostat
Potential offsets can be applied by changing Value. The Value can also be changed by moving the mouse up and down click and hold the left mouse button down on the yellow Change square and move the mouse up and down. The mouse gives an analogue movement that is similar in many ways to a turn-pot found on manual Potentiostats.
Sweep Generator
The Sweep Generator section allows very simple sweeps to be constructed. Enter your From and To potentials and the length of time the sweep will be Over. A Loop can be specified for example if Loop were set at 3 the sweep would go From-To-From-To. To start a sweep press Go the current value of the sweep is shown in Value (Potentiostat section).
