Data format
When a result array is downloaded to HyperTerminal, all of the data from
a test is sent without pause. The data flow cannot be stopped or paused.
The example shows the channel number, start date, start time and the
format of the downloaded data. BOD values in mg/L follow. Only the first
data points of a maximum of 360 equal distance points are shown. Each
line ends with a carriage return and a line feed. The end of the data
stream is shown by a message such as "Test Run to Completion" and a
dollar symbol ($).
If small negative BOD values are seen at the start of a test, refer to
Troubleshooting on page 20.
