2640A/2645A NetDAQ

Users Manual

operations refer to the instrument by BCN. NetDAQ Logger supports up to 20 instruments for operation. You cannot operate an instrument from more than one host computer at a time.

Isolated Networks

1-19.

An isolated network consists of only NetDAQ instruments and host computers. The advantages include simplified setup, faster network operation, and freedom from general network problems. Data throughput specifications are guaranteed only for isolated networks. When you install NetDAQ Logger for an isolated network, it automatically handles instrument IP addressing. You must configure your host computer networking software to use a host computer IP address of 198.178.246.1xx and subnet mask of 255.255.255.0. See “Setting Host Computer Network Parameters” in Chapter 2 of this manual.

General Networks

1-20.

A general network consists of host computers, NetDAQ instruments, and servers, routers, gateways, or other network devices. Refer connectivity issues to your network administrator and review Appendix I “Network Considerations” for more information. When you install the NetDAQ software for a general network, you must enter the instrument IP addresses manually.

Ethernet Port Selection

1-21.

Each instrument has two network ports: 10Base2 coaxial and 10BaseT twisted pair Ethernet. The instrument automatically monitors and selects the active Ethernet port. You may change ports at any time and the instrument will detect the change and automatically connect to the active port.

Asynchronous Instrument Operations

1-22.

Using NetDAQ Logger, you denote instruments as asynchronous or grouped. An asynchronous (independent) instrument controls its own scanning operations, including scan interval and method of triggering scans. NetDAQ Logger records measurement data from each asynchronous instrument in an individual data file.

Group Instrument Operations

1-23.

Using NetDAQ Logger, you can group multiple instruments to act as one instrument. NetDAQ Logger records data from all instruments in the group into a single data file. You can group up to 20 instruments for up to 400 time-correlated channels.

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.
