HIOKI ST5540/ST5541 LEAK CURRENT HiTESTER - 1

A/ewJ LEAK CURRENT HiTESTER ST5540/ST5541 Safety standards measuring instruments Leak Current Measurement - Essential to Electrical Safety 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. /www.hioki.com ) HIOKI company overview, new products, environmental considrations and other information are available on our website.

3 For Standard- and Regulation-compliance Measurement of General-use Electrical Devices ST5541 There are various standards in place concerning networks (body simulated resistance), and a standard-compliant network is required in order to make measurements. ST5541 provides standard support for standard-compliant networks (excluding medical-use electrical devices). A single, robust solution

4 ST5540/ST5541 Features ■Uninterrupted polarity switching function The ability to conduct tests without turning off the power when switching the power supply polarity dramatically reduces cycle times. The ST5540/ST5541 can switch polarity without stopping the supply of power to the device under measurement (patent pending). Old models require that the device under measurement be turned off and then back on again when switching polarity, but the ST5540 and ST5541 let you progress smoothly to the next testing process. ■Improved test reliability Blown fuse check function When measurement...
