TDF

P

Gives

ASCII decimal value

. Values

are in parameter units.

+10.00

 

 

Data output is followed b

y line feed

(ASCII

code

10)

and

 

 

 

 

end-or-identify (EOI). T

race points

are

 

separated

b

y

a comma

 

 

 

 

character .

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

TDF

M

Gives

ASCII integer

value

. Values

are in measurement units.

 

+1000

 

 

Line feed ( ASCII code 10) and EOI follow data output.
