Example of default output:
RH = 5.17 %RH T = 24.33 'C
RH = 5.17 %RH T = 24.33 'C
RH = 5.18 %RH T = 24.33 'C
RH = 5.18 %RH T = 24.33 'C
...
Command to set output format as Tdf and T with Modulus-256
checksum:
>form "Tdf =" U3 4.2 tdf " T =" U3 3.2 t CS2 \r \n
Output example:
Tdf = -15.72 'C T = 24.38 'C C9
Tdf = -15.71 'C T = 24.38 'C C8
Tdf = -15.71 'C T = 24.38 'C C8
Tdf = -15.69 'C T = 24.38 'C CF
...
Command to set output format as Tdf 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 "Tdf =" U3 3.2 tdf " T =" U3 3.2 t #003
Output example (ASCII codes not visible here):
Tdf =-15.14 'C T = 24.40 'CTdf =-15.14 'C T = 24.40 'CTdf
=-15.14 'C T = 24.40 'CTdf =-15.14 'C T = 24.40 'CTdf =-
15.13 'C T = 24.40 'CTdf =-15.13 'C T = 24.40 'C ...
