The accuracies specified for the IF8u RTDs do not include errors due to
lead resistance imbalances.
Important: To ensure temperature or resistance value accuracy, the
resistance difference of the cable lead wires must be equal to or less than
0.01 ohms.
Important: Keep total lead resistance as small as possible and less than
25 ohms.
There are several ways to insure that the lead values match as closely as
possible. They are as follows:
* Use quality cable that has a small tolerance impedance rating.
* Use a heavy gauge lead wire which has less resistance per foot.
