Power Recorder Required Equipment The cables listed in Table 3 are necessary for verification and calibration adjustment. To assemble the cables, see cable assembly figures in the Test Cables section. Table 3.
1750 Calibration Manual Verification Tests XWWarning To avoid electrical shock, personal injury, or fire: • Do not perform the calibration procedures or calibration verification tests described in this manual unless you are qualified to do so. • Repairs or servicing should be performed only by qualified personnel. The following tests are used to verify the functions of the Recorder. If the Recorder fails any of the verification tests, calibration or repair may be needed.
Power Recorder Verification Tests power analyze live view screen.bmp Figure 1. Power View Software Live View 7. Connect the calibrator NORMAL HI to inputs A, B, C, and J of the Recorder. 8. Connect the NORMAL LO to input N and the protective conductor terminal . of the Recorder. 9. Apply the voltages from Table 4 and list the Recorder readings for channels AN, BN, CN, and NG in the appropriate areas. Sine waves will be displayed for AN, BN and CN, all at the same amplitude and phase shift.
1750 Calibration Manual Neutral Voltage Verification 1. Connect NORMAL LO to A, B, C, J, and .. 2. Connect the calibrator NORMAL HI to N on the Recorder. 3. Apply the voltages from Table 5, listing the Recorder readings for the appropriate model. Table 5. Neutral (AC) Voltage Accuracy Check Applied NG Reading Limits 60 V @ Local Hz ± 1.12 V 100 V @ Local Hz ± 1.20 V 4. Verify that the N LED is on. 5. Set the calibrator to STBY, verify that the LED for N turns off. 6.

1750 Calibration Manual Watt Verification 1. Use the same connections as the CT current verification and apply 440 V and local line frequency out of the NORMAL output and 1.9 V on the AUX output. 2. Click on the power button in Power Analyze. The A, B and C should be 41.8 kW ± 0.3 kW. 3. On the calibrator press the blue button for Phase and Ref Menu. 4. Press the blue button for AUX Phase NRM. 5. Enter 90 with the numerical keypad and press Enter. The power should be 0 ± 0.1 kW.
Power Recorder Verification Tests 17. Set the calibrator to 1000 V 10 kHz. 18. Connect the voltage test cable to UUT voltage input J for approximately 15 seconds, then disconnect. Note, this signal is designated G in Power Analyze. 19. Press STBY on the calibrator. 20. Set the calibrator to 0 V 0 Hz. To Use Power Analyze to Verify the Amplitude Accuracy of Recorded Impulse Events 21. Wait two minutes for the UUT to compile event information. 22. Click on 1750 Download, and then Save. 23.

Power Recorder Calibration Calibration is controlled by 1750 Cal Wizard Software (Cal Wizard), which communicates with the Recorder over Ethernet. Cal Wizard steps through the calibration procedure, with instructions for making cable connections, setting the correct sources, and finalizing the calibration. The following steps detail the calibration adjustment procedure: 1. Connect the Recorder and the PC to the network with an Ethernet cable.
