Set a new measurement format.

sss = String consisting of modifiers and abbreviations for measured parameters. See Table 3 and Table 4. Maximum length 127 characters.

Example: show currently used measurement format (default format shown):

form
3.1 "T=" T " " U3 3.1 "RH=" RH " " U4 3.1 "Td=" Td " " U3 3.1 "Tw=" Tw
" " U3 4.1 "h=" h " " U7 \r \n

Output example:

send
T= 25.1 'C RH= 39.4 %RH Td= 10.3 'C Tw= 16.2 'C h= 45.1 kJ/kg

Example: set output format as RH and T, with start of text (ASCII character 002) and end of text (003) ASCII codes, and without line feed and carriage return at the end:

form #002 3.1 "RH=" RH U4 3.1 "T=" T " " U3 #003
OK

Output example (ASCII codes not visible here):

send
RH= 39.3%RH T= 25.1 'C
