Complete Columns A-E as follows:
A Enter the 437B present frequency Reading (W).
B Enter the 437B 50 kHz Reading (W).
C Apply power sensor correction factor for present frequency (W): CF * (Column A
entry)
D Apply power sensor correction factor for 50 kHz (W): CF * (Column B entry)
E Compute and enter Error relative to 50 kHz plus floor (%): 100 * [(sqrt(Column
