Scaling Values

For linear mVdc, Vdc, and mAdc ranges, use 0.1% tolerance resistors.
Larger tolerances may cause significant errors. Correct any errors due to
resistor tolerance with built-in linear scaling. You can also install other
components (like capacitors) for signal conditioning; please consult
Watlow Anafaze for more information.

The next table shows scaling resistor values.
