2640A/2645A NetDAQ

Users Manual

Connection Successful, but instrument has older software that will not support computed channel equations or custom RTDs!

You have successfully established communications with an instrument and can continue to operate, but you will not be able to use computed channel equations or custom RTDs.

As long as you do not attempt to set computed channel equations or custom RTDs in NetDAQ Logger, you can continue to operate with your current software. If you want to use these features, you will need to contact your Fluke Service Center for a firmware upgrade.

Constant too Large!

Your equation contains a constant that exceeds the maximum limit of 3.402823e38.

Modify the equation as necessary so no constants exceed this limit.

Conversion is complete!

Indicates the conversion for Binary to ASCII Conversion, ASCII Timestamp Conversion, or Binary to Trend Link Conversion (Utilities menu) is complete.

Converting File: [% Complete]

Gives the status of file conversion activities in percent complete for Binary to ASCII Conversion, ASCII Timestamp Conversion, and Binary to Trend Link Conversion (Utilities menu).

During file conversion, you can click the Abort button to terminate the conversion process.

Copying to different model. Some channel definitions may differ. Continue?

You are trying to copy channel configurations between different models.

Channel functions and ranges are different for each instrument. For example, the maximum volts dc range is 50V for the 2645A and 300V for the 2640A (channels 1 and 11), and there is no 2-wire RTD function for the 2645A. Click Yes to copy the channels configuration as closely as possible between instrument models, or No to cancel the operation.

Current Master instrument will become a Slave. Continue?

You are changing a Slave instrument into a Master instrument.

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