Users Manual

Unable to Open Setup File!

You have specified a setup file name or directory that does not exist.

Check your files and directories for the correct name and path. If you are using this setup file on the NetDAQ Logger command line, change the command line to a valid file name and path. (See "Starting NetDAQ Logger with a Setup File" in Chapter 3 of this manual.)

Unable to read Trend Link default template chart file - tldef.cht!

Your NetDAQ Logger installation is missing the required c:\Program Files\Fluke\netdaq\tldef.cht file.

The installation of NetDAQ Logger may be corrupted. Reinstall NetDAQ Logger following the procedures in Chapter 2.

Unable to stop scanning!

You have lost communications with your instrument and scanning cannot be stopped.

When you lose communications with the instrument while scanning, it is indeterminate if it is a network problem or an instrument problem. If it is a network problem, then the instrument continues to scan. To remedy this situation, correct the communications problem and then click the Stop Instrument button (acknowledge the "Unable to stop scanning!" message) and then click the Start Instrument button again. You can also cycle the instrument power to stop scanning.

Unable to Write to Configuration Text File!

The name you selected for the text file already exists as a Read-Only file or you have run out of disk space.

Choose a different name for the text file, remove the Read-Only property of the existing file, or free up disk space.

Unable to Write to Data File! Check disk space.

You have run out of space on the disk drive used for your data file, or the disk drive is not responding.

Check your disk medium. If you are using a floppy disk, make sure the disk has not been removed from the drive.

If you are writing to a Trend Link data file and there is still free disk space remaining on your disk drive, data logging may have been stopped due to settings

2645A, 2640A specifications

The Fluke 2640A and 2645A are advanced bench multimeters that represent a significant leap in measurement technology, designed primarily for electrical engineers and technicians who require precision and reliability in their readings. These multimeters are built to cater to complex applications in manufacturing, research, and development.

One of the standout features of the Fluke 2640A and 2645A is their high accuracy. With specifications that can reach up to 0.0035% DC Voltage accuracy, users can trust that their measurements will be consistent and precise. This is especially critical in fields like automated test equipment (ATE) where exact measurements can be crucial for product quality and safety.

Both models incorporate a large, easy-to-read display, making it convenient for users to view measurement results clearly from a distance. They also feature a wide measurement range, capable of handling a variety of tasks, from basic voltage and current measurements to more complex tasks such as resistance and temperature measurements with appropriate sensors.

The multimeters also stand out with their advanced data logging capabilities. The Fluke 2645A, for instance, can store up to 10,000 readings, allowing for extensive data collection and analysis without the need for constant monitoring. This is beneficial for long-term studies or processes that require continual oversight.

Connectivity is another key characteristic. Both the 2640A and 2645A support USB and RS-232 interfaces, which enable easy integration with computers and other devices for seamless data transfer. This feature is important for engineers who rely on software for data analysis and visualization.

Another notable technology included in these models is the Fluke Connect app compatibility, which allows users to remotely monitor measurements from their smartphones or tablets. This capability provides added flexibility, enabling technicians to work hands-free while still keeping an eye on process measurements.

Additionally, the Fluke 2645A comes with a graphical display option, allowing users to visualize measurement trends over time. This graphical representation can be invaluable for diagnosing issues or observing patterns in data.

In conclusion, the Fluke 2640A and 2645A multimeters offer exceptional performance with their high accuracy, extensive data logging, connectivity options, and advanced visualization capabilities. These features make them indispensable tools for professionals in a variety of fields, ensuring that they can achieve reliable results in their measurement endeavors.
