Packets
You must assign a packet, event, or logical expression to a counter and/or timer.
Using a Counter
To use a counter:
Step 1 Click an event to display an arrow.
Step 2 Click a counter. This causes the counter to attach itself to the bottom of the event.
An arrow automatically connects the counter to the Trigger button.
Note: For Timers, do NOT use a timer as the first event in a sequence, since this
first “event” will be the start of recording, and this is not a precise or
predictable point in time from which to start timing. Use timers only AFTER
the first event.
Setting a Counter
To set a counter:
Step 1 Open the Recording Rules page, select an event, and drag it to the Global State
or Sequence cell.
Step 2 Counts can only be set on a per channel basis, so press the Up or Down channel
buttons to select the channel on which the count is performed.
Step 3 Right-click the selected event and select Add Counter from the menu to open
the Properties dialog.
Step 4 In the text box to the right of the label Count, enter a value. Make sure the
checkbox to the left of the word Count is checked.
Step 5 Click the X in the top right corner of the dialog box to close the dialog. A counter
button should appear just below your selected event.
Changing a Counter Value
To change the counter value:
Step 1 Click the small blue dot in the upper-left corner of the counter button to display a
menu.
Step 2 Select Change Counter Value.
Step 3 Enter a new value in the pop-up dialog box. The new value appears in the
counter button.
