The board’s high-impedance isolated inputs accommodate both grounded and ungrounded thermocouple configurations.

While the board handles the physical signals, you must ensure the ToolboxST software settings match the specific thermocouple type connected to each channel pair.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Is it necessary to recalibrate the board after installation?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eA: The IS400TCATH1 arrives factory-calibrated. Since thermocouple measurements rely on millivolt-to-temperature lookup tables and onboard CJC, the system maintains accuracy automatically. Periodic \"zero\" checks via the Mark VIe diagnostic software suffice for standard maintenance.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: How do I verify a \"Cold Junction\" error?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eA: The board provides diagnostic feedback to the Mark VIe controller.
