‘Peak’ Events
Launch pulse: The first peak on the screen is the “launch pulse” which occurs
where the LT51 connects to the test leads (at a distance of 0 metres). The
distance to the cursor includes the length of the test leads.
Open: A clean or partial open will show up as a peak on the screen. The
“cleaner” the open, the taller the peak. A complete open will be the tallest peak
(other than the launch pulse). You can not see events past a complete open.
Load Coil: A load coil looks very similar to an open. If you think there is a load
coil on the pair, use the LT51 Load Coil function to verify its presence. You can
not see events past a Load Coil.
