The decimal points shown above are not actually transmitted in the data stream, but their position
is implied. The displays are configured to show the decimal point in this position.
*Time Deviation is output in two formats in the same data stream: 33
±
s.ss and 34
±
sss.sss.
Output for the 33
±
s.ss format will be +9.bb when the measured value e9.99 (b = blank).
It will be -9.bb when the measured value is less than -9.99.
Output for the 34
±
sss.sss format will observe the following conventions for out-of-range values and
leading blanks. Decimal points are implicit and do not appear in the data stream.
