4.11 Thermocouple Measurements
The OM-DAQ-USB-2401 provides effortless thermocouple (TC) measurements.
The unit includes built-in cold-junction compensation (CJC), which is
automatically invoked when you select TC measurements. The DAQ unit
automatically converts acquired voltage readings into compensated-linearized
temperature readings. A DAQ system can make thermocouple and volts
measurements concurrently.
TIP: If you experience noise from thermocouple wires, you can connect a 100K
resistor from AxL to the COM to elimate some noise. Please reference the
following diagram:
