Data Logging
The observed data could be saved in two ways;
1.
Screen capture: it saves the current screen view as a 16-bit bmp formatted image via the
‘
Print Sc
’
button numbered (18).
2.
Text formatted record of the data from ADC memory: The values in ADC memory could be recorded
as txt formatted text file via the
‘
Export
’
button numbered (26) from the Menu 3. The file size may
vary depending on the amount of data the ADC has in memory. Text format recording has much more
data than picture format and this data can be exported to Excel for detailed analysis.
Note: The internal memory should be formatted to log the data properly (see also Part 7).
