Clearing the Trend Chart 
 
Clearing the trend chart clears reading memory and restarts the reading count on 
the next trigger received.
Saving Readings
 
The readings represented by the trend chart can be saved to internal flash 
memory or to an external USB memory device as comma-separated values (CSV) 
in one measurement per line ASCII format. 
Selecting Save Readings opens the Export action window from which a path and 
file name can be selected or created. The number of readings exported is the 
number of readings in memory (Figure 6-8) at the time Export Readings is 
pressed - which may not be the total reading count (
TRIGger:COUNt x 
SAMPle:COUNt). 
Exporting readings clears reading memory and re-starts the trend chart on the 
next trigger received.
