Full Scale Range and Engineering Units
The full scale range is indicated by a two digit code. Ranges of 10 and above use the first digit to
select the leading number of the range and the second digit selects the exponent. For example,
the range code for a full scale of 1000 is 13. Only the 250 full scale uses a two letter designation
since it requires two numbers to define the range. Refer to Table 24 for a list of the order codes
for the full scale ranges.
