The active end of the RTD should be located as close as possible to the working electrode in your cell.
This will minimize the effect of thermal gradients on the control accuracy.
Cell Cables from the Potentiostat
A TDC4 in your system does not affect the cell cable connections. These connections are made directly
from the potentiostat to the cell. Please read the your potentiostat's Operator's Manual for cell cable
instructions.
Setting up the TDC4 Operating Modes
The PID controller built into the TDC4 has a number of different operating modes each of which is
configured by means of user entered parameters.
Note: Please refer to the Omega Documentation supplied with your TDC4 for information
about the various controller parameters. Do not change a parameter without some knowledge
of that parameter's effect on the controller.
The TDC4 is shipped with default settings appropriate for heating and cooling a Gamry Flexcell using a
300 W heating jacket and a solenoid controlled cold water flow for cooling.
Appendix B list the factoryTDC4 settings.
Checking TDC4 Operation
To test the operation of the TDC4, you will run a simple checkout script provided with the CPT110 Critical
Pitting Test System. The name of this script is "CHECK110.EXP". Use the procedure in the CPT110
Installation Manual to perform this checkout.
