7. Compute the maximum current and shunt voltage values (before overflow), as shown by Equation 44 and
Equation 45. Note that both Equation 44 and Equation 45 involve an If - then condition.
(44)
If Max_Current
≥ Max Possible_I then
Max_Current_Before_Overflow = MaxPossible_I
Else
Max_Current_Before_Overflow = Max_Current
End If
(Note that Max_Current is less than MaxPossible_I in this example.)
Max_Current_Before_Overflow = 62.2573 (Note: This result is displayed by software as seen in Figure 27.)
(45)
If Max_ShuntVoltage
≥ VSHUNT_MAX
Max_ShuntVoltage_Before_Overflow = VSHUNT_MAX
Else
Max_ShuntVoltage_Before_Overflow= Max_ShuntVoltage
End If
(Note that Max_ShuntVoltage is less than VSHUNT_MAX in this example.)
Max_ShuntVoltage_Before_Overflow = 0.0622573 (Note: This result is displayed by software as seen in
8. Compute the maximum power with equation 8.

9. (Optional second calibration step.) Compute the corrected full-scale calibration value based on measured
current.
