Introducing a leak current measuring instrument that complies with the IEC 60601-1 standard (3rd edition, with the ST5540), the ST5540 series feature an improved measuring method and dramatically faster cycle times, thanks to its uninterrupted polarity switching. The new devices support rated currents of up to 20A, making it more than ideal for use with products built to new standards.
Note: For applications involving leak current measurement of medical-use electrical devices, use the ST5540.
