Faster testing due to fast measurement speed
The ST5520 and ST5520-01 deliver pass/fail assessment in as fast as 50 ms. and 25 to 1000 V test voltage with 1 V resolution, shortening your test processes.
Contact check function preventing shipment of defective parts
the ST5520 comes standard with a contact check function that notifies the operator in the event of a measurement line break or faulty contact. 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.
Operator-configurable output voltage from 25 V to 1,000 V in 1 V increments
The insulation resistance measurement process involves applying a test voltage to the object under test. There is no specific test voltage commonly established for insulation testing of lithium-ion and other batteries, so the test voltage varies by manufacturer. Additionally, test voltages used for electronic components such as relays and connectors are expected to change over time to accommodate evolving standards. Consequently, Hioki made the test voltage operator-configurable from 25 V to 1,000 V in 1 V increments.
Verification of external I/O signals on the instrument's screen
On production lines where large quantities of parts are tested, measuring instruments are automatically controlled using external I/O signals. The ST5520 has functionality that enables operators to check the I/O status of these signals on its screen.
Use the RS-232C interface to capture measurement and assessment results from a PC, PLC or other system. The ST5520 is also equipped with a "data output function" for automatically sending the measurement values and assessment results at the end of each test.
Included: Instruction manual, power cord, EXT. I/O Connector and connector cover.
