All about Trace Math
Trace Math is available ONLY in CAT and NA Mode, but not in DTF
measurements.
A trace is a series of measurement data points that are connected to form a
line. This ‘live’ data trace is updated as data points are measured.
A memory trace is a live trace that has been stored in the FieldFox volatile
memory. It then becomes static, meaning it is not updated with measurements.
It can be displayed on the screen by itself, or with a data trace for comparison
purposes.
— In NA mode, memory traces are the same color as data traces, but muted
(duller).
— In CAT mode, the data trace is displayed in yellow and the memory trace is
displayed in blue.
How to display data and memory traces
—Press Trace 6.
—Then Data->Mem
to store the current live trace into memory. A ‘beep’
sounds to confirm the data trace has been saved to memory. There is no
display annotation that indicates that the memory trace has been stored.
—Press Data
to view only the data trace.
—Press Memory
to view only the memory trace.
—Press Data & Memory
to view both the live trace and the stored
memory trace.
How to perform Trace Math
Trace math is performed between a live trace and a memory trace. When one
of the following math operations are selected, the yellow data trace displays
the current measurement with the selected trace math applied. The math
operation symbol indicated below in [brackets] is displayed on the lower left
corner of the screen.
—Press Trace 6
.
— If not already stored, press Data->Mem
to store the current live trace into
memory.
—Then Data Math
.
— Then choose one of the following:
— Data + Mem
[D+M] Current measurement data is added to the data in
memory.
