Navigation wheel
Turn the navigation wheel to scroll to the desired menu option or to change the
value of the selected numeric parameter. Pressing the navigation wheel has the
same functionality as pressing the ENTER key. See ENTER key (on page 4-25)
for more information.
When changing a multiple character value, such as an IP address or channel
pattern name, press the navigation wheel to enter edit mode, rotate the
navigation wheel to change the characters value as desired, but do not leave
edit mode. Use the CURSOR keys to scroll to the other characters and use the
navigation wheel to change their value as needed. Press the ENTER key when
finished changing all the characters.
RANGE keys
Press the RANGE keys  to select the next higher or lower measurement
range on the measurement display for the selected function.
If the Series 3700 displays the overflow message on a particular range, select a
higher range until an on-range reading is displayed. Use the lowest range
possible without causing an overflow to ensure best accuracy and resolution.
You can also use these keys when entering a range value from the front panel.
For details, see Auto ranging over the front panel (on page 5-3).
If you select a range of channels, that range must stop when the channel type
changes. Therefore, you can never select a range of channels which includes
different channel types.
For more information, see Range (on page 5-1).
