2.9 Using the DFI 9000 Verify the calibration daily for best results. To use the DFI 9000, simply apply the load on the device to be measured and read the display. Recalibrate the DFI 9000 each time you use it with a different transducer. For details about using the peak detector and other options, see Section 4. -

Page 8: Options
The DFI 9000 has three options: • Peak detector • Analog voltage output • High input See below for brief descriptions of the DFI 9000 options. For more information about the options, contacts Cooper’s Sales Department at 1-800-344-3921. CF12 DFI 9000... -
Page 9: Peak Detector
In peak mode, the DFI 9000 detects and displays the highest positive peak signal level. After two conversions of the analog-to-digital converter (at 1.5 conversions per second), the unit stores the highest value. If the DFI 9000 identifies a higher peak, the peak detector reactivates to record and display the new value. -
Page 10: Erratic Readings
If the display reads close to 0000, the transducer may be faulty. Try using another transducer with the DFI 9000, calibrating first. 5. If an ovverange indication is still present, the problem may be with the DFI 9000. Return the DFI 9000 to Cooper, following our Warranty and Repair policy. -
