Performance Test

Initializing the Performance Test Setup

6-7.

Complete the following procedure to initialize the performance test setup. It is assumed you have configured the host computer and instrument as described in "Configuring the Performance Test Setup" (above). Testing begins with the instrument and host computer unpowered. This assures that at power-up self-tests are completed successfully, the correct host computer Ethernet port is activated, the host computer configuration is accurately reflected, and other background operations are completed. This procedure clears the instrument of any existing BCN, Line Frequency, and Network settings.

1.Apply Instrument Power with Configuration Reset Hold down the COMM key on the instrument front panel and apply power to the instrument. After the instrument beeps and momentarily displays "rESEt" (Reset), release the COMM key. If any self-test errors are reported on the front panel display, refer to "Self-Test Diagnostics and Error Codes" in this chapter. Configuration Reset sets the instrument to the default parameters: BCN=1, Line Frequency=60, and Isolated Network.

2.Set the Line Frequency If the ac power applied to your instrument is 60 Hz (default), continue to Step 3. If the ac power applied to your instrument is 50 Hz, complete this step.

Press the COMM key for three seconds, until a beep is heard and the SET annunciator in the display is lit. Press the up/down arrow keys until LinE (Line Frequency) is displayed in the primary display. Press the ENTER key. Press the up/down arrow keys until 50 (50 Hz) is displayed in the primary display. Press the ENTER key.

3.Apply Host Computer Power Apply power to the host computer.

4.Open NetDAQ Logger You can use Start Programs, double-click on a setup file shortcut on the Windows desktop, or double-click on a setup file name in the Windows Explorer or File Manager.

5.Add Instrument Select the Communications Config command from the Setup menu to open the Communications Configuration File dialog box. Observe the Instruments on Network list. If the list includes instrument 01 with the correct model number (model 2640A or model 2645A), continue to Step 6.

If instrument 01 is listed but with the wrong model number, select (highlight) the instrument on the Instruments on Network list and click the Modify button. Select the correct model and click OK. If instrument 01 is not listed, click the Add button and add instrument 01 with the correct model number. Click OK.

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.
