126 Ion Operations Manual
Using +% and -%
Use +% and -% to incrementally change parameter values. To access this function on Ion, press
[Shift] & [+] or [Shift] & [-]. By default, +% and -% are assigned a value of 10. This can be changed
in Setup. This can be used with any parameter.
Channel Intensity
When channels are selected, pressing [Shift] & [+] increments the intensity level by 10 (or by the
value established in setup, see {Manual Control}, page 104). Alternatively, you may press [Shift] &
[-] to decrement the intensity level by 10. You may use these keys consecutively to “add to” or
“subtract from” the intensity level.
For Example:
Select channels 1 through 10 and set them to an intensity level of 45% from the keypad.
• [1] [Thru] [1] [0] [At] [4] [5] [Enter]
Change the intensity level to 65% using +% which is set to its default value of 10% in the
setup menu.
• [Shift] & [+] [Shift] & [+]
Non-intensity Parameters
+% and -% may be used to incrementally adjust non-intensity parameters as well.
For Example:
• [1] {Iris} [Shift] & [+] [Shift] & [+]
• {Zoom} [Shift] & [-] [Shift] & [-]
