TC15– Figure 7. NI USB-9213 Terminal Assignments You can connect thermocouple input signals to the NI USB-9213. Connect the positive lead of the thermocouple to the TC+ terminal and the negative lead of the thermocouple to the TC– terminal. If you are unsure which of the thermocouple leads is positive and which is negative, check the thermocouple documentation or the thermocouple wire spool. - Page 11 The inner shield is not necessary for EMC compliance.

Refer to Figure 3 for an illustration of the NI 9940 connector backshell. NI USB-9213 Circuitry ach channel of the NI USB-9213 passes through a differential filter and then is multiplexed and sampled by a 24-bit analog-to-digital converter (ADC). Each channel also has an open thermocouple detection (OTD) circuit, which consists of a current source between the TC+ and TC–... - Page 13 Current Multiplexer USB-9213 Figure 10. Input Circuitry for One Channel of the NI USB-9213 The channels share a common ground, COM, that is isolated from other modules in the system. The NI USB-9213 common-mode range is the maximum voltage between any channel and COM. If COM is not connected, then the common-mode voltage range is the maximum voltage between any two channels.

Page 14: Cold-Junction Temperature Measurement Accuracy
Accuracy Considerations section of the Specifications for the errors for each thermocouple type when connected to the NI USB-9213. The errors do not account for the accuracy of the thermocouple itself. For the best accuracy results, keep temperature gradients across NI USB-9213 terminals to a minimum and enable the autozero channel. -
Page 15: Using The Autozero Channel
Using the Autozero Channel The NI USB-9213 has an internal autozero channel to compensate for the offset error. The NI USB-9213 specifications all assume the autozero channel is on for every sample, however, you can choose not to use the autozero channel in software. - Page 16 High-resolution mode......14.4 Hz High-speed mode......78 Hz High-resolution noise rejection (at 50 and 60 Hz) ........60 dB Overvoltage protection ......±30 V between any two inputs Differential input impedance ....78 MΩ Input current ...........50 nA NI USB-9213 User Guide and Specifications ni.com...
