Measurement results occupy the first two rows of the display. The primary display
consists of larger sized characters that comprise the 6½ digits (-1999999 to 1999999),
plus a decimal point. In the example shown above, the primary display shows
measurement results for an ac voltage measurement.
The secondary display is smaller than the primary display and located in the upper right
area of the display. However, it is also capable of displaying 6½ digits. Its function is to
display the results of a secondary measurement associated with the primary measurement.
In the example shown, the secondary display shows the frequency of the ac voltage
measurement.
The Soft Key labels, row three, identify the functions of the five soft keys just below the
display.
