To delete an instrument icon, select Setup Delete Instrument Icon. A message appears warning you that the instrument’s configuration will be lost. If you choose to delete the icon, it will disappear from the Icon Bar in the Main Window.

Designating Instruments as Group or Asynchronous

3-13.

You can designate instruments as grouped or asynchronous (standalone). NetDAQ Logger treats grouped instruments as one large instrument, logging all their scan data to one data file. A group consists of one Master instrument, and one or more Slaves. Scanning for the entire group is controlled by the configuration of the Master instrument.

For the ASCII and binary file formats, NetDAQ Logger records each Master scan along with the set of scans from the Slave instruments that match closest in time to the Master scan. NetDAQ Logger uses the timestamp for the Master as the timestamp for the whole scan record. NetDAQ Logger can best associate the Slave data with the correct timestamp when scanning for all the grouped instruments is properly synchronized. No merging of data is performed when recording in the TL format but proper synchronization is still important for accurate correlation of data between instruments. Use the following guidelines to minimize non-synchronization errors.

Wired Group

To reliably synchronize a group instrument, connect the TO (Trigger Out) line of the Master to the TI (Trigger In) of each Slave (along with a common connection to the ground terminals). Check the “Group is Externally Wired” check box in the Group Instruments dialog box. See “External Wiring for a Group Instruments” in Chapter 2 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.
