It also displays \u003cstrong\u003eprospective fault current\u003c\/strong\u003e (up to 26 kA) from loop and line measurements, so electricians can inspect and maintain an installation with one tool instead of several meters.

The Ramp test finds the trip current, and the tester also offers AC and pulsating DC (half-wave and full-wave) test types. Loop and RCD functions are specified for 220V ±10%, which includes Sri Lanka's 230V supply. It is rated CAT III 300V and is intended for 220V single-phase RCD and loop tests. The UT593 has no ×2 RCD test, which is available on the \u003ca href=\"\/products\/uni-t-ut595-multifunction-installation-tester\"\u003eUNI-T UT595\u003c\/a\u003e.

tool. If you test RCDs more than anything else, the \u003ca href=\"\/products\/uni-t-ut582-digital-rcd-elcb-tester\"\u003eUNI-T UT582+ single phase RCD tester\u003c\/a\u003e is a simpler and more compact choice. Do not test live circuits in continuity or insulation modes. The RCD and loop tests operate on a live 220V supply, so follow the safety instructions in the manual. The listed ratings are CAT III 300V.\n\u003c\/p\u003e\n\n\u003ch3\u003ePackage Includes\u003c\/h3\u003e\n\u003cul class=\"package-list\"\u003e\n  \u003cli\u003e1 x UNI-T UT593 Multifunction Tester\u003c\/li\u003e\n  \u003cli\u003e8 x 1.5V AA batteries\u003c\/li\u003e\n  \u003cli\u003e1 x Test lead set\u003c\/li\u003e\n  \u003cli\u003e1 x Carrying bag\u003c\/li\u003e\n  \u003cli\u003e1 x Manufacturer's calibration certificate\u003c\/li\u003e\n  \u003cli\u003e1 x User manual\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eDownloads\u003c\/h3\u003e\n\u003cp\u003e\n  \u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0679\/7587\/2725\/files\/uni-t-ut593-data-sheet.pdf\" target=\"_blank\"\u003e📄 Download UNI-T UT593 Data Sheet\u003c\/a\u003e\u003cbr\u003e\n  \u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0679\/7587\/2725\/files\/uni-t-ut593-user-manual.pdf\" target=\"_blank\"\u003e📄 Download UNI-T UT593 User Manual\u003c\/a\u003e\n\u003c\/p\u003e\n\n\u003cdiv class=\"product-vendor\"\u003e\n  \u003cstrong\u003eBrand:\u003c\/strong\u003e \u003ca href=\"\/collections\/vendors?q=UNI-T\"\u003eUNI-T\u003c\/a\u003e\n\u003c\/div\u003e\n\u003cdiv id=\"variant-inventory\"\u003e\u003cspan class=\"in-stock\"\u003eIn stock!\u003c\/span\u003e\u003c\/div\u003e","brand":"UNI-T","offers":[{"title":"Default Title","offer_id":53842836488405,"sku":null,"price":246500.0,"currency_code":"LKR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0679\/7587\/2725\/files\/uni-t-ut593-multifunction-installation-tester-front-view.jpg?v=1779341780","url":"https:\/\/nanozone.lk\/products\/uni-t-ut593-multifunction-loop-and-rcd-tester","provider":"Nano Zone Trading","version":"1.0","type":"link"}
