This will begin the selection process of a tag as described in the
section entitled "Select a Parameter". When you have completed
the selection process, the selected tag will be assigned to the trace,
as in Figure 3.81. To remove a tag from the highlighted trace, press
the [delete] (Backspace) key.

Setting the Trigger

nce you have assigned a tag to Trace 1, you may proceed to set the

trigger value. Three items of information are required, the trigger
type, the trigger condition and the trigger value. These are selected
for modification by pressing the [F9], [F2] and [F3] keys
respectively. (If nothing happens then you have not gained the
required access to make changes. Press the [F8] key and refer to the
section entitled

Enter/Modify an Access Level

to gain access).

There are two types of triggers possible. A Single

trigger

occurs

once and stops. The trigger must then be manually re-armed. This
is the default type of trigger. A Continuous trigger will re-arm itself
and continue to collect new trends until

viewing the contents of the

captured data stops it

. The current type of trigger is shown by either

a 'C' or 'S' in front of the Trigger label

(refer to Figure 3.81)

. To

switch between the two types, press the [F9] key.

The trigger condition and trigger value are set with the [F2] and [F3]
keys respectively. When the respective field is in reverse video, that
field may be modified.

The condition is set to one of the conditions listed below by pressing
the [cursor up] or [cursor down] keys to scroll through the

onditions.

Pressing [enter] ends the editing and accepts the shown condition.
