- Page 2 The user must make sure to discharge his-/herself from any electrical charge before touching the potentiostat (TIP: use grounded ESD-matts). Maintain the maximum input voltage of the device and the selected voltage range. Use electrically insulated thermocouples. Do not expose the PMUX-S and RMUX card to heat.

3.1 Setup PMUX-S Current Limit The Thales software has a initial current limit of ±500 mA for RMUX channels. To enable the full PMUX-S ±5 A range edit the global measurement setup. Change the PMUX installed entry from “0” to “1” as described below. - Page 7 PMUX-S 4 Connection Caution! Before connecting either the PMUX-S to the ZENNIUM PRO/X or the cells to the PMUX-S, switch off the potentiostat! The PMUX-S functions are controlled through the internal system bus, whereas the connections of the analog signals have to be set up externally. For that purpose, a potentiostat connection cable is shipped with the PMUX-S.

Blue – working electrode sense Green - reference electrode Red - counter electrode Caution! If an PMUX-S channel is used with a ZENNIUM PRO/X main potentiostat, please make sure that nothing is connected to the BNC outlets. 6 Front Panel The RMUX card has a two-digit 7-segment display. -

After the installation Thales will detect the RMUX card automatically during its start- up procedure. 7.1 Using ZENNIUM Series Potentiostat It will enable the selection of the PMUX-S channels in all RMUX compatible software sections when using the Zennium series potentiostat. 7.1.1 Testsampling & Control Potentiostat Main Menu ->... - Page 10 PMUX-S The right-hand side of the window will show the Multicell Setup, then: Main potentiostat RMUX4 channels 1 - 16 EPC42 channels 1 - 16 Displays selected channel Opens Testsampling page Opens comment window Copies all control parameters & protocol The squares on the top indicate the status of each channel: grey ->...
- Page 11 When using the PMUX-S with an external potentiostat controlled over EPC interface the channel selection differs from measuring with the Zennium series potentiostats. In general, the PMUX-S channel must be selected first and then the Thales software must be switched back to the channel of the external potentiostat PP/EL. The multiplexer routing is retained when switching to the external potentiostat.
