Maximize workload coverage in a quarter of the time
The Fluke Calibration 5322A Multifunction Electrical Tester Calibrator combines many functions into a single instrument, replacing discrete resistors, decade boxes and other custom solutions commonly used to calibrate electrical safety testers. It’s flexible and precise enough to calibrate a wide range of instrumentation, and fast enough to handle the job in a quarter of the time you spend on manual multi-product methods.
Insulation resistance testers
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, 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 TΩ and 10 kV. The included 10 kV divider measures testers to 10 kV with greater precision than the 40 kV probe, insuring you get the TUR you need for these tests.
Leakage current testers
Simulate leakage current for direct/touch, differential and substitute leakage current methods with 10 µA 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.
Multifunction installation testers
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.
Portable appliance testers (PATs)
The 5322A has all the functionality needed to calibrate PATs, with insulation resistance, ground bond, leakage current RCD, flash voltage and load test capabilities.
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 5322A 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 or a discrete 4-wire 10 mΩ resistor to cover even more workload.
Loop/line impedance testers and ground bond testers
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. Ground bond resistance outputs are either 2-wire or 4-wire. The lowest 4-wire output is 1 mΩ.
Residual-current device (RCD) or ground fault current interrupter (GFCI) testers
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.
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. 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. The 5 kV range also measures hipot ripple coefficient and distortion (THD).
For measurement 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. 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 MET/CAL® Calibration Management Software advantage
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.
The support you need, when you need it
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. (CarePlans are not available in all countries. Please check with your local Fluke Calibration sales representative for calibration services in your area).
Flexible choices to calibrate your electrical tester workload
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.
To either model, add active loop compensation and a 600 V precision ac/dc output source for calibrating the voltage measurement function of DUTs. You can also add a characterized 40 kV probe accessory for making precision measurements of very high voltages to 0.5% accuracy.
Included accessories offer additional flexibility
Each 5322A comes with an external R-Multiplier to source resistances of up to 10 TΩ for testing insulation testers to 10 kV. 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.
Optional 5322A-LOAD
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 supports 5 kV testing and has nine high voltage resistors, ranging from 10 kΩ to 10 Ω, that can be combined in parallel, within voltage limits, to obtain more precise results.
