y [ Entry Off]

You can use this key to clear and turn off the active entry area, as well as any displayed prompts, error messages, or warnings. Use this function to clear the display before printing or plotting. This key also helps prevent changing active values accidentally by moving the knob.

The backspace key has two main functions:

nDeletes or modifies entries

nHides the softkey menu

Modifyiug or Deleting Entries

You can use the backspace key to delete the last entry, or the last digit entered from the numeric keypad. You can also use this key in one of two ways for modifying a test sequence:

n deleting a single-key command that you may have pressed by mistake (for example
..//.i/:::.....:... i	......,...,,.,.,.,...; _;__,”‘;,::;.;; “,,:,:,:,:,:,:,~,:,” ‘““i’.” :....:::.::::
~~~~~~~~~~~a,: ~~~~~:~~;.;)
.	.*.	..^_

ndeleting the last digit in a series of digits that you may have input, as long as you haven’t yet pressed a terminator (for example if you pressed @ 112) but did not press m, etc)

Turning off the Softkey Menu

The @ key can also be used to move marker information off of the graticules and into the softkey menu area. The softkey menu is turned off in this mode.

This function is useful when marker information obscures the display trace and you wish to see the display traces more clearly.

This is a toggle function: repeatedly pressing B alternately hides the softkey menu and makes it reappear If two or more markers are on, marker annotation will move off of the graticules and into the softkey menu area when the menu is hidden. Pressing L-J, or a hardkey which opens a menu, or any softkey, restores the softkey menu and moves marker annotation back onto the graticules.

You can use this key to add a decimal point to the number you entered.

Q

You can use this key to add a minus sign to the number you entered.
