PC time earlier than existing Trend Link data! Verify PC time, wait [nn] seconds, or create a new Data Set.

This message indicates that the Trend Link Data Set you are trying to initialize or log to has a timestamp that is newer than the current PC time.

This message can occur under the following conditions:

The Instrument clock is slightly faster than the PC clock. If NetDAQ Logger runs for several days, then when the instrument is stopped, the last recorded timestamp may be later than the PC time. In this case, wait for the PC time to “catch up” before trying to initialize the Trend Link data file for collecting additional date. For example, if the PC time is 1 minute behind the instrument time, wait at least 1 minute before restarting. You can also create a new Trend Link Data Set.

The PC clock is losing time. Reset the PC clock to the correct time. If this problem continues, you may have to replace the battery in your PC that powers the internal clock.

The PC clock is set to a new time. You will not be able to log data to an existing Trend Link file after changing the PC clock to a time earlier than the timestamps in the Trend Link file. To continue, let the PC time catch up to the time recorded in the timestamps or create a new Trend Link file.

Performing Rollover.

This is a status message that appears at the end of converting a binary data file to a Trend Link data file. It indicates that the Trend Link *.now file just created by the conversion procedure is being rolled over into a *.tlg (history) file.

Plot Maximum must be larger than Plot Minimum!

You tried to configure a Quick Plot where the plot maximum was less than the plot minimum.

Change your Quick Plot maximum and minimum values such that the maximum value exceeds the minimum value.
