Bio-Rad BioLogic Signal Import Module (SIM) - Manual (Page 84)

3.6.3 pH Monitor
The pH monitor, available as an option from Bio-Rad, (refer to section 2.5.4 for more information) may be
connected to the DuoFlow system in one of two ways:
• To a Workstation connect the Signal Import Module (SIM) included with the pH Monitor. The SIM
connects to the DuoFlow Workstation through the bus communication cables (System Cables 17,
18, 19, 21, or 30).
• To a Maximizer, if in use, connect to the rear BNC connector labeled pH.
Figure 3-11. pH Monitor
To connect the Bio-Rad pH electrode to the SIM,
1. Connect the output cable from the pH electrode to the connector labeled pH Connector on the SIM.
2. Connect the SIM to the USB Bitbus Communicator by using an Instrument Bus cable (System
Cables 17, 18, 19, 21, or 30), as shown below.
3. Connect an external power source to the USB Bitbus device (see Section 2.1.2).
