The tests mainly verify accuracy and offset of voltage and current inputs. Tests indicated with (*) are optional. They can be done to check if the Analyzers hardware (analog input channels) is OK. Bear in mind that the outcome of these checks is rather influenced by hardware sanity than by Calibration Adjustment. Accuracy of all other Analyzer functions is linked to input accuracy and is embedded in the software. This link is tested extensively for each new software release. This testing is done with the Fluke 6100A Electrical Power Standard and 6101A Auxiliary units. This setup allows multiphase operation and direct testing of measuring functions such as flicker, harmonics, interharmonics, fluctating harmonics, dips the test pattern as shown in Figure 3-1 may be not visible or hardly visible. Observe the display closely, and verify that the display shows no abnormalities, as for example very light pixels or lines. Figure 3-1. Display Pixel Test Pattern 7. Press F2 . The test pattern is removed; the Analyzer shows Contrast (CL 0100): 8. Press F2 again to do the next step Contrast (CL 0110): 9. Press F3 CALIBRATE The Analyzer shows the display test pattern shown in Figure 3-1, at default contrast. Observe the display closely, and verify that the display shows no abnormalities. Also verify that the contrast of the upper left and upper right square of the test pattern is equal. 10. Press F2 . The test pattern is removed; the Analyzer shows Contrast (CL 0110): 11. Press F2 again to do the next step Contrast (CL 0120): 12. Press F3 CALIBRATE The Analyzer shows a light display; the test pattern as shown in Figure 3-1 may not be visible or hardly visible. Observe the display closely, and verify that the display shows no abnormalities. 13. Turn the Analyzer OFF and ON to exit the calibration menu and to return to the normal operating mode. If the maximum, minimum, or default display contrast is not OK, then you can set these items without performing a complete calibration adjustment; refer to Section 4 for detailed information.
