44. For all A dc steps, calculate the output with the formula below. Use the appropriate conversion to
convert from base units to units for the specific evaluation step.
45. With the entire table populated, evaluate each step for compliance to limits. If Guardbanding is to
be applied, create a table from the example in this manual, where the acceptance limits are
properly modified by your Guardbanding method.
