RTD Measure Verification
1. Push repeatedly until RTD is shown in the third row of the Product display.
2. Connect the 720URTDA to the Product.
3. Connect the 720URTDA Current HI to the 5522A HI RTD Output.
4. Connect the 720URTDA Sense HI to the 5522A HI RTD Output.
5. Connect the 720URTDA Current LO to the 5522A LO RTD Output.
6. Connect the 720URTDA Sense LO to 5522A LO RTD Output.
7. Set the 5522A to output the resistance setting in Table 5, and verify that the
display readings on the Product are within the limits.
