i[Battery ] – This outputs the word between the brackets [ ].
z257 – This outputs the fixed string ‘Voltage’.
space – This outputs an ASCII space.
f6:1 – This takes the value from location 2 and outputs it in a field with a total
width of 6 characters. There is 1 decimal place available within the field.
z273 – This outputs the fixed string ‘CrLf (carriage return line feed)’.
