Error and Status Messages

Current Master instrument will become Async. Continue?

You are changing an Asynchronous instrument into a Master instrument.

A group instrument consists of a Master and one or more Slaves. If you redefine an Asynchronous instrument as a Master, the old Master becomes an Asynchronous instrument. Click Yes to proceed or No to cancel the operation.

Currently logging instruments will be stopped!

You tried to exit NetDAQ Logger while instruments are still logging.

If you wish to exit and stop all logging, click OK. To keep the application open until logging has stopped, click Cancel.

Demo Version of NetDAQ Logger - 60 minutes is up!

Your NetDAQ Logger demonstration software has been in operation for 60 minutes.

Close the application. You may open the application again for another 60 minutes of operation, if desired.

Demo Version of NetDAQ Logger - will stop after 60 minutes!

You will be able to use the NetDAQ Logger software in the demonstration mode for up to 60 minutes.

After the 60 minutes is over, the message "Demo Version of NetDAQ Logger - 60 minutes is up!" appears. You must close the application and, if desired, open it again for another 60 minutes of operation.

Duration Interval must be greater than zero!

You tried to enter a duration interval of 0 or else entered extraneous characters.

Enter a duration interval greater than 0. The format is Hours:Minutes:Seconds.

Entered values do not generate valid Mx+B values!

Your Input Range and Scaled Range values for the Mx+B calculation generate invalid M and/or B values.

Enter Input Range and Scale Range values such that M and B are less than +9.9999E+9.
