Users Manual

Move your instrument to a less loaded subnet of your network or isolate the NetDAQ instruments on their own network.

If possible, increase the scan interval.

Use the Fast Binary file format rather than CSV or Trend Link formats.

Make sure that there are few or no other Windows applications running at the same time as NetDAQ Logger.

Upgrade to a faster PC and disk drive and increase the amount of RAM in your PC.

Disable the Windows Screen Saver function or make sure that it doesn’t activate during data collection.

Turn off Trend Link, QuickPlot, and Spy in NetDAQ Logger and don’t open any dialog boxes in NetDAQ Logger.

Close any dialog boxes that you have open in NetDAQ Logger. Avoid operations which open dialog boxes, such as configuring an instrument, while logging data at high speed.

Load smartdrive during PC boot or use vcach with Windows for Workgroups. Use of disk caching utilities increases throughput to the data files. However, data could be lost if the PC crashed suddenly due to power failure or malfunction.

Make sure the disk drive that you’re writing the data files to is not fragmented. Disk fragmentation develops during a long period of writing and deleting files on the disk. Use a defragmentation utility (like Norton speedisk) to reduce this problem.

If you’re using a general network that is loaded by other communication, isolate your instruments and host computer onto separate wiring and a separate host computer interface adapter from general network communication. If you must still communicate via the general network, consider installing two network adapters in your host computer and communicate only with NetDAQ instruments on one adapter and wiring (see “Running Two Network Cards in a PC” in this appendix).

6.Interaction with advanced display adapter driver packages.

A very common software interaction exists between network support software and advanced display adapter driver and support packages. If your network software doesn’t load or operate properly, try selecting the standard VGA driver in Windows Setup under the control panel. If the problems go away, contact your display adapter vendor for the latest version of their display adapter driver and associated support software. If using the latest version doesn’t fix the problems, you may have to use a less capable display adapter driver package when running the NetDAQ and other networking software.

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.
