ASCII
The ASCII (CSV) data file format stores the data in ASCII characters and is directly compatible with analysis applications like Excel and Lotus 1,2,3. If you use a spreadsheet for data analysis, then the ASCII (CSV) data file format may be the best choice.
You can covert an ASCII file to text. The text data file format is the same as the ASCII format, except that the timestamps have been converted into date/time strings using the Converting Data File ASCII Timestamps procedure (Utilities menu). The default file extension for text data files is *.txt.
∙
Data files contain the measurement data collected from the instruments. After the instrument completes a measurement scan, the data is stored temporarily in the instrument’s internal memory. NetDAQ Logger retrieves the scan data over the network and records it into a data file. Data files are recorded in one of three formats: Fast Binary, ASCII, or Trend Link.
A summary of each data file type is as follows. ∙ Fast Binary
The Fast Binary data file format provides the fastest way of getting data to disk and uses the least amount of disk space. Fast Binary is the only data file format that you can convert directly to the other two data file formats: ASCII (CSV) and Trend Link. The NetDAQ Logger Utilities menu lists the conversion utilities for Fast Binary files.

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.
