This interface allows you to exchange calibration data with the Fluke Documenting Process Calibrator 74X and 75X series models. By means of wizards, you can download (export) tag number calibration settings to the calibrator, and after collecting the calibration data, you can upload (import) calibration data into Smart Instrumentation for the required calibrated tag numbers.
When performing calibrations using the Fluke interface, there are two special forms
that come shipped with Smart Instrumentation: d_ff_default_fluke_result.psr and d_ff_default_fluke_settings.psr. These forms can be found on the hard drive where you installed the application under
the 'Program Files(x86)\SmartPlant\Instrumentation\PSR' folder. For more information
about using and assigning forms, see Specification Pages, Spec Forms, and PSR File Customization Using InfoMaker.
Important Information when Using your Fluke Calibrator over a WAN Connection (Citrix Environment)
In order to use the Fluke calibrator over a WAN connection (Citrix environment), to upload or download data to Smart Instrumentation, please make sure you have installed the latest firmware update on your Fluke calibrator.
-
If you have difficulties or need more information please contact Fluke technical support @ (800)44-FLUKE.
-
If you are working on a Citrix console to which a Fluke Calibrator is connected, to enable the software to detect the calibrator on the serial port located on the client computer, you must first map the serial port to the client computer. For details, see Map a Serial Port to Use the Fluke Calibrator on a Citrix Console.
-
When uploading or downloading data from your Fluke device over a WAN connection, the data transfer can take some considerable time. It is recommended that before using your Fluke device over a WAN you;
-
Ensure that the battery is fully charged
-
Ensure that the Auto Battery Save feature is disabled
This will prevent the Fluke device from shutting down while data is being transferred.

When performing calibration checks with the Fluke calibrator, discrepancies could arise between the values entered in Smart Instrumentation and the values downloaded to the Fluke calibrator. These discrepancies are caused by differences in the number of decimal places allowed by Smart Instrumentation and the Fluke calibrator resolution causing the calibrator to round up or down downloaded values.
-
For example, temperatures in the Fluke Documenting Process Calibrator are limited to one tenth of degree Celsius resolution. If the downloaded value has two or more decimal places, the values are rounded by the Fluke calibrator and therefore are different to those in Smart Instrumentation. This causes unexpected deviations from the anticipated point levels that will be reflected in the calibration result points.
-
For more information on the level of accuracy for the different values measured by your Fluke calibrator, please consult your Fluke documentation or Fluke support.
-
When not interfacing with the Fluke (using manual data entry), Smart Instrumentation determines the expected output based on linear distribution of the number of points in terms of input values (that is % of input range). Fluke however, linearizes the number of points based on the output range. The transfer function is still the same.
-
When working with square root output calculations, due to the high slope at the range < 1% of input, Fluke linearizes the transfer function between 0 to 1% of input range. The Calibration module has aligned this strategy with Fluke so that same expected results are displayed in Smart Instrumentation.
-
When setting the source mode to manual, Fluke prompts % of output for the source value for square root calculation. This is standard Fluke behavior. Smart Instrumentation has aligned the task’s parameters for this case when downloading the task to the Fluke calibrator. However, when uploading such results, Smart Instrumentation translates these values back to engineering values using the Ranges fields from the calibration settings. This results in different values being displayed between the Fluke and Smart Instrumentation, however the errors are the same.
