Industry’s Fastest Testing Speed
The Insulation Tester ST5520 delivers the fastest insulation resistance testing in the industry, meeting all the requirements of production lines thanks to rapid takt times.
Rapidly assess in as fast as 50 ms
Testing is complete in as little as 50 ms — the fastest time in the industry. This is 700 ms faster than legacy Hioki models.
Quickly discharge residual voltage
The post-test residual voltage discharge time has been reduced significantly compared with legacy models. As a result, when comparing an identical sample under the following conditions, a takt time improvement of 990 ms is estimated.
Prevents errors due to poor contact
The contact check function allows you to check that proper contact has been made with the device under test prior to the testing. This ensures that resistance testing is not carried out without proper contact, as this can result in erroneous assessment.
There are two methods: 4-wire contact check and comparator contact check.
Stops potential defects from reaching the market
With this function, a low voltage (2 V to 4 V DC) is applied to the test patterns to check for micro-shorting prior to insulation testing.
Safe, easy operation at your fingertips
The use of optional Switched Probe 9299 lets you to operate the ST5520 while holding the probe.
