    Yo u can connect thermoco u ple inp u t signals to the NI 9214.Connect the positive lead of the thermoco u ple to the TC+ terminaland the negative lead of the thermoco u ple to the TC terminal. If

    yo u are u ns u re which of the thermoco u ple leads is positive andwhich is negative, check the thermoco u ple doc u mentation or thethermoco u ple wire spool.

    The NI 9214 also has two common terminals, COM, that areinternally connected to the isolated gro u nd reference of themod u le. A connection to COM is not necessary for mostapplications. Specifically, leave COM u nconnected forconfig u rations in which all thermoco u ples are floating, allthermoco u ples are referenced to the same common-mode voltage,or one thermoco u ple is referenced to a common-mode voltage andall others are floating.

    However, for config u rations in which two or more thermoco u plesare referenced to different common-mode voltages, connectingCOM according to the following g u idelines improves

    common-mode rejection performance. Connect COM to chassisgro u nd if the common-mode to chassis voltages are smaller than1.2 V. Otherwise, connect COM to a valid common-mode voltagereference that is within 1.2 V of the common-mode voltages of allthe thermoco u ple inp u ts.

    Each thermoco u ple channel also has a resistor between theTC+ and COM terminals and between the TC and COMterminals. Beca u se long thermoco u ple wires can act like resistors,

    the bias c u rrent from the OTD circ u it can ca u se small offset errors.The gain and offset errors res u lting from the so u rce impedance ofconnected thermoco u ples are negligible for many applications. Thermoco u ples with a higher lead resistance can introd u ce moresignificant errors. Refer to the Compensating for OTD Current

    section for information abo u t compensating for offset errorsca u sed by bias c u rrent and lead resistance. Refer to theSpecifications section for more information abo u t errors res u ltingfrom so u rce impedance.

    The channels share a common gro u nd, COM, that is isolated fromother mod u les in the system. The NI 9214 common-mode range isthe maxim u m voltage allowed between any channel and COM. TheNI 9214 meas u res the common-mode voltage level of each channeland ret u rns a warning in the software if the signal is o u tside thecommon-mode voltage range. Refer to the Specifications sectionfor more information abo u t the common-mode voltage range.

    The NI 9214 s u pports high-resol u tion and high-speed timingmodes. High-resol u tion timing mode optimizes acc u racy and noiseand rejects power line freq u encies. High-speed timing mode

    information abo u t setting the timing mode, or conversion time,in software. Visit ni.com/info and enter c s erie s doc forinformation abo u t C Series doc u mentation.

    Temperature Measurement AccuracyConsiderationsTemperat u re meas u rement errors depend partly on thethermoco u ple type, the acc u racy of the thermoco u ple, thetemperat u re being meas u red, the resistance of the thermoco u ple

    wires, and the cold-j u nction temperat u re. Refer to the Temperature Measurement Accuracy section in the Specifications section for themod u le acc u racy for each thermoco u ple type when connected tothe NI 9214.

    For the best acc u racy res u lts, keep temperat u re gradients acrossNI 9214 terminals to a minim u m, n u ll the lead wire resistance, andenable the a u tozero channel. Refer to the Minimizing ThermalGradients section, the Compensating for OTD Current section,and the Using the Autozero Channel section for more information.

    Cold-Junction Temperature Measurement AccuracyThe NI TB-9214 has three cold-j u nction compensation channels.Heat dissipated by adjacent mod u les or other nearby heat so u rcescan ca u se errors in thermoco u ple meas u rements by heating u p theNI 9214 terminals to a different temperat u re than the cold-j u nctioncompensation sensor. The thermal gradient across the terminalscan ca u se the terminals of different channels to be at differenttemperat u res, in which case the res u lting meas u rement createserrors not only in absol u te acc u racy b u t also in the relativeacc u racy between channels. Refer to the Specifications section forthe cold-j u nction compensation acc u racy specifications. Thethermoco u ple acc u racy specifications incl u de the errors ca u sedby the thermal gradient across the NI 9214 terminals forconfig u rations with the NI 9214 terminals facing forward oru pward. Refer to the Temperature Measurement Accuracy sectionin the Specifications section for the thermoco u ple acc u racyspecifications.

    Minimizing Thermal GradientsThermal gradients can be ca u sed by changes in the ambient airtemperat u re near the front connector or by the thermoco u ple wireif it cond u cts heat or cold directly to the terminal j u nctions. For the

    best acc u racy res u lts, follow these g u idelines for minimizingthermal gradients: Use small-ga u ge thermoco u ple wire. Smaller wire transfers

    less heat to or from the terminal j u nction. If yo u are u sing a low channel co u nt on the mod u le, insert the

    foam pad in the NI TB-9214 opening. Refer to the Connectingthe Signals section for more information.

    R u n thermoco u ple wiring together near the NI TB-9214 tokeep the wires at the same temperat u re.

    Avoid r u nning thermoco u ple wires near hot or cold objects. Minimize adjacent heat so u rces and air flow across the terminals. If possible, u se the foam pad in the NI TB-9214 opening to

    restrict airflow aro u nd the terminals. Keep the ambient temperat u re as stable as possible. Make s u re the mod u le terminals are facing forward or u pward.

    Keep the mod u le in a stable and consistent orientation. Allow the thermal gradients to settle after a change in system

    power or in ambient temperatu

    re. A change in system powercan happen when the system powers on, the system comes o u tof sleep mode, or yo u insert/remove mod u les. Refer to thewarm- u p time in the Specifications section for moreinformation.

    Compensating for OTD CurrentThe OTD c u rrent ca u ses a voltage error on the inp u t when p u shingagainst a so u rce resistance. This error is minimal for manyapplications, b u t can be significant for some applications thatreq u ire high acc u racy and u se long, narrow ga u ge thermoco u plewires that ca u se large so u rce resistances. Refer to theSpecifications section for more information abo u t the OTD biascu rrent.

    Yo u can also eliminate the OTD bias c u rrent by disabling the OTD.Refer to the software help for information abo u t config u ring theOTD circ u it. Visit ni.com/info and enter c s erie s doc forinformation abo u t C Series doc u mentation.

    Yo u can compensate for the OTD bias c u rrent if yo u r applicationreq u ires high acc u racy, high resistance thermoco u ple wires, andthe ability to detect open thermoco u ples. Take a meas u rement withthe OTD enabled and a second meas u rement with the OTDdisabled. The voltage difference between the meas u rements isthe error voltage d u e to the OTD bias c u rrent. S u btract the errorvoltage from s u bseq u ent meas u rements.

    Using the Autozero ChannelThe NI 9214 has an internal a u tozero channel, which can besu btracted from each thermoco u ple reading to compensate foroffset errors. Use of the a u tozero channel is optional, however theNI 9214 specifications ass u me that a u tozero is applied to everysample. Refer to the software help for information abo u t u sing theau tozero channel. Visit ni.com/info and enter c s erie s doc forinformation abo u t C Series doc u mentation.

    Sleep ModeThis mod u le s u pports a low-power sleep mode. S u pport for sleepmode at the system level depends on the chassis that the mod u le is

    plu gged into. Refer to the chassis man u al for information abo u tsu pport for sleep mode. If the chassis s u pports sleep mode, referto the software help for information abo u t enabling sleep mode.Visit ni.com/info and enter c s erie s doc for informationabo u t C Series doc u mentation.

    Typically, when a system is in sleep mode, yo u cannotcomm u nicate with the mod u les. In sleep mode, the systemcons u mes minimal power and may dissipate less heat than it doesin normal mode.
