occurs, you must reconfigure communications to add the network parameters (select the Communications Config command from the Setup menu).

ROM Failure! Continue?

Your instrument has detected a fault during internal performance monitoring.

This message does not appear under normal operating conditions. Note the message and click Yes to continue operations or No to terminate operations. If the fault recurs, stop operations, and cycle instrument power. If the fault still persists, remove the instrument from service and return it to a Fluke Service Center for repair, along with a description of the error message.

RTD Alpha value must range from 0.00374 to 0.00393!

You entered an out-of-range RTD probe constant Alpha value.

Enter a value between 0.00374 and 0.00393. The default is 0.00385055.

RTD R0 value must range from 10 to 1010 Ohms!

You entered an out-of-range RTD R0 (ice point).

Enter an R0 value between 10 and 1010 Ohms. The default is 100 Ohms. (The R0, or ice point, refers to the resistance of the RTD at 0 degrees C.)

Sampling interval must range from 1 to 3600 seconds!

You tried to select a Quick Plot X-Axis Sampling Interval that was less than 1 second or more than 3600 seconds.

Reenter a Sampling Interval that is between 1 and 3600 seconds. The Quick Plot displays 40 interval points on the plot.

Select at least one group average channel!

You selected the Average Computed Channel or the Difference from Average function but did not specify any channels to average.

Select at least one channel from the Group Average list box for the Average Computed Channel function.

Select at least one spy channel!

You selected the Spy window but did not specify any channels to spy on.

Select at least one channel from the Channel list box for the Spy window feature.

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.
