Attempt to set instrument to invalid time - Verify your PC time!

When logging starts, the instrument time is set according to the clock on your PC. If your PC date and time settings are invalid, the instrument time cannot be set and this message will appear.

Reset the date and time on your PC. If this message continues to appear, check your PC’s clock batteries and replace if necessary.

Attempt to start Trend Link failed!

Trend Link could not start.

Make sure Trend Link is installed. Note the directory used for the installation and try again. If prompted for the directory location, enter the path to the location of the Trend Link installation. If Trend Link is not installed, see the procedures in Chapter 2.

Bad calibration input value - Check your source!

Your calibrator did not input a valid calibration value to the instrument.

Check your calibrator output, particularly for 4-wire connections (Ohms for example) as the calibrator must be configured for both Sense and Source.

Base Channel Number must range from 1 to 99!

You tried to enter the number 00, or other characters. Select a number in the range 01 to 99.

Batch information in data set has been corrupted!

This will occur when NetDAQ Logger starts logging into an existing Trend Link data file for which the batch information has been corrupted. The best workaround is to start logging into a new Trend Link data file.
