Trace Memory
A memory trace is a pulse measurement Tr 1 data trace (NOT the trace in the
Zoom window) that has been stored in the FieldFox volatile memory. It then
becomes static, meaning it is not updated with normal pulse measurements. It
can be displayed on the screen by itself, or with a pulse trace for comparison
purposes.
The Tr 1 data trace is displayed in yellow.
The memory trace is displayed in blue.
