Preparing for Operation 2

Instrument Preparation

Reviewing and Setting the Base Channel Number

2-30.

Perform the procedure in Figure 2-17 to review or set the Base Channel Number (BCN). The BCN identifies the instrument. The BCN is also the first two digits of the Global Channel Number (GCN), which uniquely identifies each instrument channel. For example, a GCN of 2716 indicates instrument 27 and analog channel 16. (See Figure 2-18 for examples.)

BCN Range The BCN can be any number from 01 to 99. If you plan to install NetDAQ Logger for isolated network operation, each instrument on the network must have a unique BCN.

BCN Review or Set identifier The REVIEW annunciator displays when reviewing the BCN; the SET annunciator displays when setting the BCN.

ENTER

Press the COMM key to review the Base Channel Number (BCN), or press and hold the COMM key for 3 seconds to set the BCN.

Press the up/down arrow keys until bASE (Base Channel Number) appears

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

Press the ENTER key. bASE appears in the secondary display and the current BCN (two digits) in the primary display.

For BCN set procedures, press the left/right arrow keys to select the BCN 10s or 1s digit position (highlighted).

Press the up/down arrow keys to select the desired number, 0 to 9, for the

positioned BCN digit. In this manner, set both BCN digits.

Press the ENTER key to exit. (Pressing any other function key will cancel set operations.)

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.
