Features
Verify insulation performance with waveforms and values (Waveform display function)
The Hioki ST5680 is a DC Hipot tester that can perform DC withstand voltage testing and insulation resistance testing in compliance with a variety of safety standards. In addition to generating PASS/FAIL judgments, the instrument can display and record applied voltage waveforms and leakage current waveforms acquired during testing. Its ability to visualize and analyze testing is useful from a test traceability standpoint.
Waveform display of applied voltage and measured current
The behavior of the applied voltage and measured current can be checked by monitoring the waveforms. In addition, the instrument can display voltage, current, and resistance measured values as a time series so that behavior can be reviewed. It can also display an enlarged view of just the waveforms for more detailed review. In this way, the Hioki ST5680 lets you analyze results immediately in the field, without using a computer.
Advantages of the waveform display
By analyzing waveforms during testing, you can infer the causes of defects in production processes. And by identifying those causes and improving the processes, you can improve production efficiency.
Analyzing defective parts returned from the market
You can also look back at results, at the waveform level, from shipping inspections of products that were later returned due to defects. By improving the standards based on which PASS judgments are made, you can boost production quality.
Promoting inspection quality
The ability to record and manage waveforms is useful from an inspection traceability standpoint. By developing higher-quality testing structures, you can increase the trust of customers.
Prevent minuscule failures due to arc discharges (Arc discharge detection function)
The Hioki ST5680 DC Hipot Tester can detect arc discharges, which are caused by residual materials like burrs and cuttings. By correctly identifying parts with minuscule insulation defects as defective, the instrument helps prevent the risk of hazards such as fires and accidents caused by heating after shipment.
Preventing testing do-overs due to erroneous judgments (Contact check function)
The instrument can determine whether it has made proper contact with the test target by measuring the capacitance between the measurement terminals (stray capacitance and the capacitance of the test target).
Ideal for withstand voltage testing of batteries, motors, electronic components, and other parts
The Hioki ST5680 DC Hipot Tester tests insulation performance by applying a high voltage to the test target. It’s capable of performing safety testing for a broad assortment of targets, including electronic devices, electronic components, and materials, in settings ranging from R&D labs to production lines. For batteries, it’s used to perform withstand voltage testing between the enclosures and electrodes of modules, packs, and cells.
Output voltage: Max. 8 kV Output current: Max. 100 mA
The Hioki ST5680 DC Hipot Testerprovides two modes: DC withstand voltage test mode, which evaluates insulation by measuring the leakage current in the test target, and insulation resistance test mode, which evaluates insulation by measuring resistance.
In DC withstand voltage testing, it can output up to 8 kV, one of the highest values for any instrument of its kind. Test cycle times can be reduced since it can charge test targets quickly with high-capacity, 100 mA output, even if the target includes a capacitance component.
Perform tests without worrying about the capacitance component.
Even if your test target includes a capacitance component, an overshoot-resistant design ensures the Hioki ST5680 won’t exceed the set voltage when applying voltage to the target, allowing you to perform tests with peace of mind.
In addition, you can set a delay time so that no judgments are made while the charging current continues to flow, helping prevent erroneous judgments.
High-precision judgments with a maximum resolution of 0.001 μA
As the insulation performance of batteries and motors improves, there’s growing demand for the ability to use ever more minuscule current values to generate PASS/FAIL judgments in withstand voltage testing. If you use a withstand voltage tester with low resolution, you won’t be able to accurately measure leakage current. Since the Hioki ST5680 realizes high-precision performance with a maximum resolution of 0.001 μA, it can accurately measure minuscule leakage currents and use them to generate PASS/FAIL judgments.
Insulation breakdown voltage (BDV) measurement function
The Hioki ST5680’s BDV function can check the insulation breakdown voltage of the test target. It can increase the applied voltage at a set speed and check the voltage that leads to insulation breakdown. Test methods are defined by standards, including continuous voltage rise testing and stepped voltage rise testing. The Hioki ST5680 can perform both tests. The instrument can be used to evaluate insulation performance (dielectric strength) in R&D work.
