Instrument Preparation

Viewing the Instrument Ethernet Address

2-36.

Perform the procedure in Figure 2-28 to view the Instrument Ethernet address. (See Figure 2-29 for examples.) The network administrator must know the instrument Ethernet address when the instrument operates on a general network. You do not need this information when you operate the instrument on an isolated network. For your convenience, record the Ethernet address inside the rear cover of this manual.

Ethernet Address Format The Ethernet address is a 12-digit hexadecimal number. For example, 00:80:40:12:34:56. The first 6 hexadecimal digits represent a manufacturer, for example, 00:80:40 represents Fluke Corporation. The remaining digits are a sequential number assigned during manufacturing. Ethernet addresses are always unique; they are never altered, reused, or duplicated.

Ethernet Address Display The Ethernet address display consists of six 2- digit segments: Eadr 0 to Eadr 5. In the example above, Eadr0=00, Eadr1=80, Eadr2=40, Eadr3=12, Eadr4=34, Eadr5=56.

ENTER

COMM

Press the COMM key to open the communications display because this is a review process only.

Press the up/down arrow keys until EAdr (Ethernet Address) appears in

the primary display (comm appears in the secondary display).

Press the ENTER key. Eadr0 appears in the secondary display, the first 5 digits of the Ethernet address appears in the primary display (always 00.80.4).

Press the left/right arrow keys to display each byte: Eadr0 (always 00), Eadr1 (always 80), Eadr2 (always 40), then Eadr3, Eadr4 and Eadr5.

Press the COMM key again to exit. Record the Ethernet address inside the rear cover of this manual.

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.
