5.1.4 Equipment Required For Calibration
The primary source instrument used in the calibration procedures is the Fluke 5500A. If
a 5500A is not available, you can substitute another calibrator as long as it meets the
minimum test requirements.
• Fluke 5500A Multi Product Calibrator, including SC300 or SC600 Oscilloscope
Calibration Option.
• 50Ω Coax Cables (4x): use Fluke PM9091 (1.5m, 3 pcs.) and PM9092 (0.5m, 3 pcs.).
• 50Ω feed through termination (4x), Fluke PM9585.
• Male BNC to Dual Female BNC adapter (3x), Fluke PM9093/001.
• Dual Banana Plug to Female BNC Adapter (1x), Fluke PM9081/001.
5.2 Calibration Procedure Steps

1. Select the Calibration Mode, section 5.3
2. Do the Contrast Calibration Adjustment, section 5.4
3. Do the WarmingUp & PreCalibration, section 5.5
4. Do the Final Calibration, section 5.6
5. Save the Calibration Data and Exit the calibration mode, section 5.7
6. Do the probe Calibration, section 5.8
The following partial calibrations are allowed:
• Contrast calibration, do the above-mentioned steps 1, 2, and 5.
If during normal operation the display cannot be made dark or light enough, or if the
display after a Test Tool reset is too light or too dark, you can do this calibration.
• Probe calibration, do the above-mentioned step 6.
The probe calibration matches the probe to the used input channel.
