TB-9212 Calibration Procedure
Verification
The following performance verification procedure describes the sequence of operation and
provides test points required to verify the TB-9212. The verification procedure 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 TB-9212.
1.
If you are using a TB-9212 with screw terminal, loosen the captive screws and remove the
top cover. If you are using a TB-9212 with mini-TC, you do not need to remove the top
cover.
2.
Connect the thermocouple calibrator to the TB-9212 using the barrier strip assembly
created in the
Building the Barrier Strip Assembly
section. Refer to Figure 2 for a
connection diagram.
