Hipot Current Calibration Load Resistors

The 5320A-LOAD High Voltage Load Adapter is an accessory to the Fluke 5320A Multifunction Electrical Tester Calibrator. It loads a hipot tester to create the leakage current needed to perform hipot tester calibration with the Fluke 5320A Multifunction Electrical Tester Calibrator.

The 5320A-LOAD consists of a series of eight power-rated resistors configured to provide eight resistance taps from 10 kΩ to 5 MΩ. Used to provide a resistive load on the test signal generated by a hipot tester, the test voltage and the resulting current through the Load is tested and calibrated by the 5320A calibrator.

Because of the high voltages created by hipot testers, the 5320A-LOAD is designed to withstand a maximum voltage from 1.2 kV to 5.5 kV, depending on the selected resistor. During the hipot calibration test, the 5320A measures the actual test voltage and leakage current from the hipot tester. These measurements are used to verify/calibrate similar measurements made by the hipot tester being calibrated.

The 5320A-LOAD comes standard with a traceable calibration certificate including verification data. An optional 17025 accredited calibration certificate is available for an extra charge.

The 8508A/CASE is a sturdy case available for transporting the 5320A-LOAD.

The design of the 5320A-LOAD allows it to be placed on top of or under the 5320A calibrator for convenient operation and a small footprint.
