Maximize your workload coverage with the 5320A Calibrator

The 5320A Multifunction Electrical Tester Calibrator combines many electrical calibration functions into a single instrument, replacing the resistors, decade boxes and other custom solutions commonly used to calibrate electrical testers. It’s flexible and precise enough to calibrate a wide range of instrumentation.

Multifunction installation testers

The 5320A has all the functionality needed to calibrate installation testers with insulation resistance, continuity, loop, RCD and earth resistance test capabilities.

Portable appliance testers (PATs)

The 5320A has all the functionality needed to calibrate PATs, with insulation resistance, ground bond, leakage current, flash voltage and load test capabilities.

Insulation resistance testers

The 5320A calibrator sources high ohms, high voltage resistors and measures the high voltage output of megohm meters and other portable and bench insulation testers. When calibrating insulation resistance testers up to 1 kV, you can select a wide range of continuously variable resistance values, from 10 kΩ to 10 GΩ, with 4 ½ digit resolution and one single value of 100 GΩ. When calibrating 5 kV insulation testers, the external 10 kV dual function adapter extends the resistors’ range up to 10 TΩ. The adapter functions both as a 1000: 1 voltage divider to 10 kV, and as a x1000 resistance multiplier to 10 TΩ.

Continuity testers and earth (ground) resistance testers

To calibrate these low ohms testers, a calibrator must be able to source precision low ohms. From its low ohms precision resistors, the 5320A calibrator sources resistance values ranging from 100 mΩ to 10 kΩ, with 3 ½ digits of resolution. Choose 2-wire or 4-wire modes for maximum flexibility.

Loop/line impedance testers and ground bond testers

The 5320A calibrator has 16 high power, high current resistors it can source, to increase the resistance of a loop or line by a known amount. Use Scan mode to automatically determine the resistance of the loop, and use Active Loop Compensation mode to compensate for any residual impedance in the loop or line.

Residual-current device (RCD) or ground fault current interrupter (GFCI) testers

The 5320A simulates a circuit breaker (an RCD/GFCI) to verify and calibrate trip current and trip time, with a wide range that enables it to accurately handle most models in this instrument category. For most RCD testers, trip times are calculated to an uncertainty of 0.25 ms, to provide better than 4:1 test uncertainty ratios (TUR). Trip current uncertainty is 1 %, which also provides better than 4:1 TURs in most applications.

Leakage current testers

Simulate a leakage current for direct/ touch, differential and substitute leakage current methods with 4 ½ digit resolution from 0.1 mA to 30 mA. The 5320A lets you choose the method that works best for your test, unlike other calibrators that only offer a single method.

Voltmeters

Many testers have built-in voltmeters. But you don’t need an additional calibrator to test this part of the workload. The model 5320A/VLC calibrator adds a precision voltage source to 600 V with 0.1 % accuracy, to calibrate V ac and V dc meters.

Hipot testers

Electrical safety testing with hipots is an integral part of development and manufacturing of electronic and electrical products, ranging from refrigerators to power supplies to test equipment to cables. Such testing is often required by government regulations to ensure product safety. The Fluke 5320A provides best-in- class hipot calibration of ac and dc voltage. The built-in 1000 V meter measures voltage and current. For voltages over 1 kV, Fluke offers two accessory items: a 10 kV adapter or 40 kV probe. With the 10 kV adapter, ac voltages to 10 kV can be calibrated with 0.5 % accuracy. Either item can be used with the built-in meter to measure voltage or flash voltage over 1000 V.

Medical safety testers

With the broad functionality and high accuracy of the 5320A, calibrating medical safety testers is a snap, allowing you to add these items to your calibration workload.
