3 Phase Power Quality Analyzer
Accuracy Verification Procedure
17
W Caution
Be careful when you set the calibrator output voltages. High voltages applied to
the current input will damage the Product.
To measure current:
1. Connect the Voltage-to-Current Input Cable Assembly to the Analyzer current probe input.
See Ta b l e 3 .
2. Connect the 3PHVL-1730 "N" lead and the single test lead Earth to the calibrator AUX LO.
3. Connect the calibrator AUX HI output to the 3PHVL-1730 L1+L2+L3 leads.
4. Stack the 17xx Calibration Cable Assembly together: red to red and black to black.
5. Plug the attenuator into the calibrator Normal HI and LO.
6. Connect the stacked Calibration Cable Assembly to the attenuator. Connect the black
leads to NORMAL LO.
Note
For accurate results, it is important to connect the 17xx Calibration Cable Assemblies
to all four current inputs on the device.
7. For all ranges in Ta bl e 1 1 , set the calibrator to the voltages indicated in the given order.
Check that the values are between the limits.
8. When finished, set the calibrator to Standby.

[1] Calibrator Output Impedance and Analyzer loading will effect actual voltage being applied. Fluke
recommends that you use a divider and the Calibrator Tool described above.
