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
á and â keys to move
the flashing digit.
These keys move the flashing digit in a numeric entry field to the right or left.
