Error and Status Messages

Token String is too Large!

This equation exceeds the limit of 1000 bytes after it’s been converted into binary format.

Once equations are converted into binary format (so they can be read by the instrument) they cannot exceed 1000 bytes in length. To reduce this equation’s length, reference other computed channels (average, difference, and difference from average) in the equation.

Trend Link data file paths must begin with a drive letter. Universal Naming Convention (UNC) path names are not supported at this time.

This will occur in the 32-bit version only, in the Data File Configuration dialog box, when the user has selected an UNC path name for a Trend Link data file name.

Trend Link Data Set file not found! Close Trend Link, start logging again, and then reopen Trend Link.

A Trend Link data file that Trend Link is currently accessing has been deleted. Exit Trend Link, begin logging data again, and then re-open Trend Link.

Trend Link Data Set .NOW file already exists! Delete the Data Set or create a new Data Set.

You are attempting a Fast Binary (BIN) to Trend Link (SET) conversion using an existing Data Set name that contains a *.now file.

Choose new Trend Link file names when converting Fast Binary files instead of using existing names.

Trend Link file prefix must be 7 characters or less!

Your Trend Link data file name has 8 characters instead of 7 (or less) characters.

Trend Link file names are a maximum 7 characters (plus extension). For example, testdat.set. This is necessary because the data set directory is the same name as the data file name, preceded by an underscore, e.g., the data file testdat.set is in the directory _testdat.set.

Trigger Interval must range from 0 to 24 hours (86400 seconds)!

You tried to enter a Trigger Interval greater than 86400 or tried to enter extraneous characters.

Enter numbers only between 00000.000 and 86400.000 for the Primary Interval.

Fluke 2640A, 2645A user manual Token String is too Large, Trend Link file prefix must be 7 characters or less

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.
