The arrow keys are the same as the up-down-left-right keys on a connected PC keyboard and are used to navigate screens, dialogs, and entry fields. The up and down keys also function as increment and decrement controls during active function entry.
Rotating the knob increases or decreases a numeric value, or moves the highlight to the next digit, character, or item in a list. Press the knob to enter the current value or make a selection.
Same as the backspace key on a connected PC keyboard. Used to edit or correct numeric and textual entries. It can also be used in file dialogs to navigate back up a directory tree.
This front-panel key performs the following functions:
Cancels dialogs
Cancels active function
Returns you to local control (if in remote)
Returns the GUI to the home screen
When the instrument is controlled remotely, any hardkey that is pressed on the front panel generates a message that says "Instrument is in Remote. Press ESC to return to Local." The exception is the Home key, which takes the instrument out of remote operation.
When the instrument is also in the local lockout state (LLO), the Local key is locked out as well. In this case, when the Local key is pressed, a message is generated that says "Local key is locked out by remote computer. Cancel Local Lockout on computer or release remote control." When you get this message, you should disconnect the remote computer, or use it to take the instrument out of the local lockout state.
If an external keyboard is connected, the Esc key performs the Cancel action but without returning the GUI to the home screen, as the Home front-panel hardkey would do.
The number pad is the same as the number pad on the PC keyboard.
The number keys and decimal point add to the current entry, if there is a numeric entry in progress. If there is not a numeric entry in progress, they open the numeric keypad and put the number of the key pressed (or a decimal point) into the entry area.
The +/– key on the number pad negates the current entry, if there is a numeric entry in progress. If there is not a numeric entry in progress, it opens the numeric keypad and puts a preceding minus into the entry area.
This button immediately executes an armed trigger when the Trigger Source is set to Key. It is equivalent to the Trigger button (
