4. PLOTX - EXTENSIONS

The program “PLOTX” is an extended version of “PLOT” with capacity to handle circular log buffers, multiple plotter colour options and various data processing options such as maximum, minimum and average. It does this at the expense of FTU memory. On a 16K FTU the amount of free memory available for RAM command files is severely restricted.

4.1RUNNING PLOTX

1.Load PLOTX into the FTU. Connect datacassette or Data Logger to FTU

2.Type:- RUN then press Return

3.Answer questions as for PLOT

4.1.1 PLOTX - Operator Responses

The questions asked by “PLOTX” are the same as “PLOT” with the following additional questions which relate to “PLOTX” extended features.

QuestionMeaning

Buffer number (0-7)number of buffer to unload & optional

(,log size)buffer log size if using a circular buffer in the data logger

Enter the buffer number (followed by the log size if unloading a circular buffer)

PLot Format,

F

=

Formatted input. (set of B,L,C)

Pointers & buffer

P

=

Buffer & Pointer format

Bypass, Skip buffer

B = Bypass data unloaded using “F” or “B”

or Done?

S = "

" “P”

 

D =Done (ready to

Plot)

 

plot Scales, Line or

S = Scales are drawn every interval

 

None?

L = A vertical Line is drawn every interval

 

N = No indication is required of intervals

This command allows

extra scale indications to be drawn on the
