These keys let you scroll through choices in a parameter list that apply to a
specific command. Parameter lists are circular; you can return to the starting
position by continuously pressing either key. If the command has a numeric range,
these keys increment or decrement the existing value. In meter mode, these keys
can be used to adjust the magnitude of the output voltage or current. Only the
flashing digit is changed by these keys. Use the
"

Enter is
pressed, the dc source returns to Meter mode.
