NI TB-9214 Calibration Procedure

Initial Setup

Complete the following steps to set up the NI TB-9214.
1.

Install NI-DAQmx.

2.

Make sure the NI cDAQ-9178 power source is not connected.

3.

Connect the NI cDAQ-9178 to the system safety ground.
a.

Attach a ring lug to a 14 AWG (1.6 mm) wire.

b.

Connect the ring lug to the ground terminal on the side of the NI cDAQ-9178 using 
the ground screw.

c.

Attach the other end of the wire to the system safety ground.

4.

Install the NI 9214 in slot 8 of the NI cDAQ-9178 chassis. Leave slots 1 through 7 of the 
NI cDAQ-9178 chassis empty.

5.

Connect the NI cDAQ-9178 chassis to your host computer.

6.

Connect the power source to the NI cDAQ-9178 chassis.

7.

Launch Measurement & Automation Explorer (MAX).

8.

Right-click the device name and select 

Self-Test

 to ensure that the module is working 

properly.

Verification

The following performance verification procedure describes the sequence of operation and test 
points required to verify the NI TB-9214 and assumes that adequate traceable uncertainties are 
available for the calibration references.

Terminal Block CJC Verification

Complete the following procedure to determine the As-Found status of the NI TB-9214.
1.

Loosen the captive screws and remove the top cover from the NI TB-9214.

2.

Connect the thermocouple calibrator to the NI TB-9214 using the barrier strip assembly 
created in the 

Building the Barrier Strip Assembly

 section. Refer to Figure 3 for a 

connection diagram.
