12* is displayed, for example, at the completion of the next
measurement.
This value ( 0.00012) is the small difference between the signal being
measured and the reference value ( OFFS: 10.00000 MHz ) obtained in
step 5.
Using the reference allows you to observe small differences in the
13th–15th digits which would not be observable in the 12-digit display.
