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.
