Using the Freeze Button to Compare Loops

You can freeze the Loops screen and select a reference loop for
comparison. When real-time data refreshing resumes (by
pressing the Freeze button again), the selected loop will remain
in the background behind the real time graphic.
To create a reference loop refer to Figure 4–6, Figure 4–7, and
Figure 4–8 and do the following.

Saving a loop

Press the Freeze button to freeze the loop you wish to use as a
reference then press the Save Loop touch screen display in the
right hand bar, beneath the frozen graphic display (Figure 4–6).
This puts the selected loop into memory and places a time
reference into a field in the left hand bar beneath the graphics
display as shown in Figure 4–7. A total of four (4) loops can be
saved at one time. When the fifth loop is saved, the oldest loop
is removed.

Creating a reference loop

Press the touch screen directly over the touch screen field
in the left bar which represents the saved loop you wish to use
as a reference. The field will highlight (Figure 4–7). Press the
"Ref Loop ON/OFF" field on the right hand bar (Figure 4–6 and
Figure 4–8) to turn the reference loop on.
When you press the Freeze button again, the reference loop remains visible in the background, while the active display
places current loops in real time over the top of it.
To turn off the reference loop, freeze the screen again and press the Ref Loop On/Off toggle button shown in Figure 4–8.
