Users Manual

Packet Driver A network device driver specification defined by 3COM. Packet drivers support operation of only a single protocol stack over the driver and hardware interface.

PC Personal Computer. A much misused term usually used to refer to a computer built to comply with the IBM PC defacto standards. Also used to refer to just about any small computer.

PC Port Address The Intel X86 processor architecture supports addressing of I/O devices in a separate address space from memory. The PC/AT architecture supports 1024 of these I/O device addresses, commonly called port addresses. In most cases, each I/O device (including network adapter cards) are assigned one or more port addresses to allow the software to communicate with the interface hardware.

PING Packet Internet Groper. A program for testing if a host with a specified IP address or name is reachable on the net. Some PING programs report statistics about the path to the host that is found.

PLA Parallel to LAN adapter. A network interface adapter device that plugs into the standard parallel interface (Printer Port) of an IBM PC or clone.

Port Also called an application port or socket port. A number used to identify a specific connection to an application using TCP services. TCP uses port numbers to provide multiple connections between applications in one host and applications in one or more other host.

Proxy ARP A protocol used by Routers and Gateways to establish inter-subnet routine paths automatically during the execution of an ARP between two hosts.

Network Protocol A standard procedure for regulating data transmission between computers.

net.cfg A file in a standard format used to hold configuration information for an ODI driver.

Protocol Stack A group of software packages that work together to implement a network protocol. These packages are usually arranged so that one package communicates with at most two other packages, one that implements a lower level of the protocol and one at a higher level. This is why the collection is called a “Stack”.

protocol.ini A file with a standard format used to hold configuration information for NDIS drivers.

Repeater A device used to physically isolate and extend the length of a network wiring segment.

RFC Request For Comment. RFC documents describe all aspects and issues associated with the International Internet and the TCP/IP protocol. Whenever a

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.
