A unique feature is the AC Voltage indication on the LCD display. It also features a milli-amp (mA) trip setting with a separate test button. The unit can be set from 10mA, used for testing saturation and to eliminate nuisance tripping, to 35mA. The bright neon indication assists the user in confirming the wiring status of the circuit under test. Simply plug the MT310 into a wall socket and the results are clearly displayed. For additional safety, the MT310 is rated at CAT IV 300V and CAT III 600V.<\/strong><\/p>\n<p><strong>Major tech polarity tester MT310<\/strong><\/p>\n<p><strong><a href=\"https:\/\/allairaircon.co.za\/product-category\/tools-and-multi-meters\/major-tech-meters\/\">Find more major tech tester here\u00a0<\/a><\/strong><\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/section>\n","protected":false},"excerpt":{"rendered":"<h1 class=\"product_title entry-title\"><strong>Socket ELCB Tester<\/strong><\/h1>\n<p><strong>Features : <\/strong><\/p>\n<ul>\n<li><strong>Compact, lightweight and easy to use<\/strong><\/li>\n<li><strong>Correct Wiring Indication with neon lights<\/strong><\/li>\n<li><strong>Operates on 230V systems<\/strong><\/li>\n<li><strong>AC Voltage measurement on LCD display<\/strong><\/li>\n<li><strong>Fixed current settings from 10mA to 35mA<\/strong><\/li>\n<li><strong>Separate test button<\/strong><\/li>\n<li><strong>Double injection rubber housing<\/strong><\/li>\n<\/ul>\n","protected":false},"featured_media":8426,"comment_status":"open","ping_status":"closed","template":"","meta":{"_acf_changed":false},"product_brand":[],"product_cat":[270,338,336,265],"product_tag":[],"class_list":{"0":"post-5944","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_cat-major-tech-polarity-tester","7":"product_cat-major-tech-meters","8":"product_cat-sales-items","9":"product_cat-tools-and-multi-meters","11":"first","12":"instock","13":"taxable","14":"shipping-taxable","15":"purchasable","16":"product-type-simple"},"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO Premium plugin v27.3 (Yoast SEO v27.3) - https:\/\/yoast.com\/product\/yoast-seo-premium-wordpress\/ -->\n<title>Major tech polarity tester MT310<\/title>\n<meta name=\"description\" content=\"Major tech polarity tester MT310.
