TREND DATA PRINTOUT (ASCII MODE)
The format of data displayed when a trend printout is requested is
similar to that of the real-time data
. The only differences are that
“TREND” is displayed in the top row instead of the “CRC:
XXXX” software verification number and there is no “Status”
column.
Readings are displayed in 2-second intervals
. The values on each
row are an average for the 2-second period.
At the end of the printout an “Output Complete” line indicates
that the transmission was successful
. If the “Output Complete”
line is not present, a corruption of the data may have been
detected and the data should be ignored.

Once a trend printout has begun, the NPB-295 must be turned off
and back on again before a new trend printout can begin
. A trend
printout cannot be aborted without turning off the NPB-295 or the
printer.
TREND DATA PRINTOUT (GRAPH MODE)
The graph mode disables all printout functions except trend data.
