The 5320A Multifunction Electrical Tester Calibrator combines many 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.
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.
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.
