I took some data in error the other day and have deleted the spectra and waveform data using Stored Data Management, but cannot figure out how to correct the trend.

In Periodic Measurement Point Data Delete Options - DM-14 you are given ranges of trend, spectral, and waveform data to delete. In spectral and waveform data you can chose none, all, last or selected but in trend data you are only given none, all or last. The trend data that I want to delete is the next to last.

Any ideas on how to delete this trend data?

Thanks,

I have done this in the past. DM14 screen, ranges of trend, spectral, & waveform data -- choose ALL. then go to the Limit Time Span? check box and enter date and time of the data I want to remove. It worked for me. Hope this helps

Tommy is correct.

One thing, to remember, you have to enter the hour, minute and second range you need to delete. If you overlap into any data you want to keep by one second, it will be deleted also.
