Develop a Performance History
A Fluke Calibration specification is a set of performance limits that all products must
meet. To maintain consistent quality, Fluke calibrators are specified with enough margin
to include temperature, line, and load extremes, plus additional margin for production.
This means that a typical Calibrator in a typical environment operates inside 50 % of
specification limits. For some exacting applications, it can be helpful to know just how
accurately a particular Calibrator operates. The proper way to do this is to accumulate a
performance history by calibrating regularly and recording results on a control chart.
Calibrating regularly and recording the results on a control chart is tedious and requires a
large array of equipment. The Calibrator calibration check feature is an alternative with
some distinct advantages:
•
Calibrated check standards are already programmed into the unit. External standards
are not necessary.
•
The process is consistent and automatic and it does not require operator assistance.
Each calibration check produces a new set of data points for accumulating a historical
record. When this process is externally automated, significant history can be accumulated
much faster than with a manual calibration.
Save Calibration Reports
Calibration reports can be created and exported to a USB flash drive from the Calibrator
Calibration Report menu. The subsequent sections describe the reports.
To save a calibration report:
1. Put a flash drive into the front USB port.
2. Go to Setup Menu>Calibration>Generate Report.
3. Select one of the three reports:
•
Save Calibration Shifts
•
Save Check Shifts
•
Save Raw Data
Once an item is selected, the report is loaded to a USB flash drive. The report is in
comma separated value (CSV) format and is capable of being imported into a spreadsheet
program such as Microsoft Excel.
4. Open or print the file from the PC.
