The 5322A Electrical Safety Tester Calibrator helps calibration technicians comply with new regulatory standards, now up to four times faster than previous methods.

The 5322A calibrator sources high-value, 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 5 kV divider and multiplier access, you can select a wide range of continuously variable resistance values, from 10 kΩ to 100 GΩ with 4.5-digit resolution. When calibrating 10 kV insulation testers, the included R-multiplier extends these ranges to 10 T ohms and 10 kV measurement extends the resistors’ range up to 10 TΩ and 10 kV. The included 10 kV divider is used to measure testers up to that voltage level with greater precision (than the 40k V probe), insuring you get the TUR you need for these tests.

Simulate a leakage current for direct/touch, differential and substitute leakage current methods with 4.5-digit resolution from 0.1 mA to 30 mA. The 5322A lets you choose the leakage current test method that works best for your situation, unlike other calibrators that only offer a single method.

The 5322A makes quick work of these multifunction installation testers with the flexibility to calibrate insulation resistance, continuity, loop impedance, RCD and earth resistance tester capabilities. This means that calibrations are completed with one instrument.

The 5322A has all the functionality needed to calibrate PATs, with insulation resistance, ground bond, leakage current RCD, flash voltage and load test capabilities.

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 3.5 digits of resolution. Choose 2-wire or 4-wire modes for maximum flexibility to 10 mΩ resistance and lower test uncertainty ratios (TURs).

The 5322A 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 (5322A/VLC) to compensate for any residual impedance in the loop or line.

The 5322A simulates a circuit breaker (an RCD/GFCI) to verify and calibrate trip current and trip time, without tripping the installation’s current breakers. 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. The 5322A also has a special PAT RCD mode to calibrate the RCD function of those 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. Such testing is often required by government regulations to ensure product safety.

The 5322A provides best-in-class hipot calibration of ac and dc voltage. The built-in meter measures voltage and current for voltages up to 5 kV. For voltages over 5 kV the included 10 kV divider accessory or optional characterized 40 kV probe can be used. The 10 kV divider measures voltages to 10 kV with 0.5 % uncertainty. The built-in meter also measures hipot ripple coefficient and distortion (THD).

For calibration of hipot current up to 100 mA, Fluke Calibration offers a load adapter accessory. Use the load adapter in conjunction with the 5322A built-in current meter for full calibration of hipots.

The 5322A calibrator works with Fluke Calibration MET/CAL Calibration Software, in 5320A emulation mode, allowing you to increase throughput up to four times that of traditional manual and multi-product methods while ensuring calibrations are performed consistently every time. This powerful software documents calibration procedures, processes and results for ease in complying with ISO 17025 and similar quality standards.

Fluke calibrators are known for their accuracy and reliability. Fluke operates global calibration and repair facilities to keep your equipment in top working order. Reduce your calibrator downtime and control your cost of ownership with a Priority Gold service package. Fluke Calibration CarePlans feature an annual standard or accredited calibration of your 5322A calibrator with guaranteed turnaround and no cost for repairs.

Multiple model choices for the 5322A give you the flexibility to select the features best suited to your lab’s workload. The base 5322A model offers 1.5 kV high resistance sourcing.

The 5322A/5 offers 5 kV high voltage resistor sourcing to handle the growing population of high voltage based safety testers. Add to either model active loop compensation and a 600 V precision ac/dc output source for calibrating devices under test (DUTs) with metering capabilities, or a characterized 40 kV probe accessory for precision measurement of very high voltages to 0.5% accuracy.

Each 5322A comes with an external R-Multiplier to source resistances of 10 TOhm for testing insulation testers. A RCD PAT adapter is also included for safe secure connections to the 5322A for your specific regional electrical appliance plug and socket type. Also included is an external 10 kV divider to measure testers with 10 kV outputs, to meet more stringent test accuracy ratios required by some regulations.

This broad range of model options put you in control of selecting the right model to match your workload and your budget.

An optional 5322A-LOAD 5 kV high resistance load option is available with 5 kV high voltage resistors to allow direct connection to hipots for leakage tests. This 5322A-LOAD is unique in that it not only supports 5 kV but has nine high voltage resistors, ranging from 10 KOhm to 10 MOhm, that can be combined in parallel, within voltage limits, to obtain more precise results.
