2 The Modify Keys
You use these keys to edit parameters. For the purposes of editing, there are
two types of parameter. One type is the parameter that can have one of several,
separate values, these are discrete valued parameters. The second type is the
parameter that can have any value between certain limits, these are continuous
valued parameters.
Editing Discrete Valued IParameters
When selecting one of several discrete values, the (J) selects the next highest
value and the (J) selects the next lowest value.
Example The averaging time can have only particular values. If you are
editing this parameter and it is currently 200ms, pressing (J)
changes the value to 500ms. If you are editing this parameter
and it is currently 200ms, pressing (J) changes the value to
100ms.
O and have no effect in the editing of discrete valued parameters.
Editing Continuous Valued Parameters
Where a value is being set from between certain limits, you can edit each
character individually.
The changes the editable character to the next one on the left. The
changes the editable character to the next one on the right. The editable
characters include each digit of numeric parameters, the decimal point (see
below), and characters in messages. When a character is selected for editing it
blinks.
Pressing (J) decrements the editable character. The (J) increments the editable
character.
Editing Units
Tb edit the magnitude of Watt values, select the decimal point as the editable
character. Use the (JQ to move the decimal point to the left, use (J) to move the
decimal point to the right.
When the decimal point reaches its rightmost or leftmost position, pressing the
key again changes the multiplier of the units.
