Outputting measurement values as binary numbers
The internal results values are scaled so that whole numbers are output. Result values are scaled by being
divided by the values from Table 6–31 (page 275). All binary numbers are output with 32 bits (4 bytes).
The numbers are stored in "big-endian" format, i. e. the larger bytes are stored first.

1 Space characters (20 hex) are displayed as underscores "_" in this table.
2 The number of digits before and after the decimal point for the torque and gradient depends on the maximum
torque for the tightening spindle.
