It has the ability to quickly test and display the resonant frequency F0 of various loudspeakers, and real-time display the test voltage value. It can set the upper and lower limit ranges according to the specifications of the loudspeaker, and judge whether the loudspeaker is qualified or not by the test of pass\/fail judgment circuit, so it is especially suitable for testing in the production line.<\/p>","protected":false},"excerpt":{"rendered":"<div class=\"e_richText-58 s_title clearfix response-transition\">ZC5990D loudspeaker F0 tester is a special test equipment with excellent testing precision, accuracy and stability. When the test frequency range is set to 400Hz, the resolution can be up to 1Hz, and the smaller the test frequency range, the higher the resolution, which is very favorable to the F0 test of low-frequency loudspeaker (box). The 4.3-inch color LCD display can directly display the F0 curve of the loudspeaker.<\/div>\n<div class=\"e_container-19 s_layout response-transition\">\n<div class=\"cbox-19-0 p_item\"><\/div>\n<\/div>","protected":false},"featured_media":5596,"comment_status":"open","ping_status":"closed","template":"","meta":{"themepark_post_bcolor":"#f5f5f5","themepark_post_width":"1022px","themepark_post_img":"","themepark_post_img_po":"left","themepark_post_img_re":false,"themepark_post_img_cover":false,"themepark_post_img_fixed":false,"themepark_post_hide_title":false,"themepark_post_main_b":"","themepark_post_main_p":100,"themepark_paddingblock":false},"product_brand":[3538],"product_cat":[2020,52],"product_tag":[2027],"class_list":{"0":"post-4245","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_brand-zctek","7":"product_cat-electroacoustic-device-testing-equipment","8":"product_cat-tydzcs","9":"product_tag-f0","11":"first","12":"instock","13":"shipping-taxable","14":"product-type-simple"},"_links":{"self":[{"href":"https:\/\/ad.wbyq.cn\/en\/wp-json\/wp\/v2\/product\/4245","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/ad.wbyq.cn\/en\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/ad.wbyq.cn\/en\/wp-json\/wp\/v2\/types\/product"}],"replies":[{"embeddable":true,"href":"https:\/\/ad.wbyq.cn\/en\/wp-json\/wp\/v2\/comments?post=4245"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/ad.wbyq.cn\/en\/wp-json\/wp\/v2\/media\/5596"}],"wp:attachment":[{"href":"https:\/\/ad.wbyq.cn\/en\/wp-json\/wp\/v2\/media?parent=4245"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/ad.wbyq.cn\/en\/wp-json\/wp\/v2\/product_brand?post=4245"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/ad.wbyq.cn\/en\/wp-json\/wp\/v2\/product_cat?post=4245"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/ad.wbyq.cn\/en\/wp-json\/wp\/v2\/product_tag?post=4245"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
