4.3.3 Screen Keys (Contd.)
4.3.3.3 Introducing Deviation and Offset Values
Pressing the '∆' key (bottom row) presents a screen with ∆% and ∆V labelling the two top
right screen keys:
Pressing the '∆%' screen key adds
the 'Percentage Deviation' value
to the lower left of the display
presentation and the screen reverts
to the main DC Voltage display
as shown below. The Deviation
value is limited to ±10% of the
Output value.
Pressing the '∆V' screen key adds
the 'DC Voltage Offset' value to
the lower right of the display
presentation and the screen reverts
to the main DC Voltage display
as shown below.
Note that as each of the '∆' keys is
pressed to show its value on the
screen, the cursors will move to
the latest selection.
The main DC Voltage display is
shown here with both ∆% and ∆V
additions in place. This would
require two separate operations
of the ∆ key on the bottom row, as
after each selection, the screen
reverts to the main display, the
cursors following the new
selection. After reversion, the
cursors can be transferred to any
of the displayed values for editing,
here shown on the main output
display. Otherwise, the operation
of the editing keys is unchanged
(paras 4.3.3.2), and direct editing
can also be used
