The transformer scanning test program covers all kinds of transformer low-voltage measurement parameters. Including inductance, leakage inductance, turn ratio, DC resistance, impedance, coil-to-coil capacity and other primary parameters; quality factor, series equivalent resistance and other secondary parameters, as well as short-circuit inspection. High-speed digital sampling technology and scanning test fixture (A132501) design, so that the previous time-consuming and inefficient transformer production inspection becomes accurate and fast.<\/p>\n<p>The 3250\/3252\/3302 also provide a variety of output impedance modes for selection, making it possible to solve the problem of inductance difference caused by the difference in test current between test instruments due to the difference in test output impedance. In addition, the inductance conversion method is provided in the turn ratio measurement technique, which can improve the turn ratio measurement error caused by high leakage ratio of low coupling coefficient transformers.<\/p>\n<p>In addition to the transformer scanning function, the 3252\/3302 also provides the LCR Meter function, which can be applied to various parts for incoming and outgoing inspection, R&amp;D analysis or production line automation applications.<\/p>","protected":false},"excerpt":{"rendered":"<div class=\"sub-title\">Product Features<\/div>\n<ul>\n<li>Test frequency 20Hz~200kHz\/1MHz, accuracy 0.02%<\/li>\n<li>Basic measurement accuracy: 0.1%<\/li>\n<li>Three impedance output modes to choose from, and the measurement results are fully comparable with the LCR meters of well-known brands.<\/li>\n<li>Enhanced Turn Ratio for accurate measurement of low permeability cores.<\/li>\n<li>High-speed LCR measurement, up to 80 times\/sec.<\/li>\n<li>High-speed DCR measurement, up to 50 times\/sec.<\/li>\n<li>Graphical and tabular displays are available for scanning frequency, voltage and overlap current measurements (3252\/3302).<\/li>\n<li>Built-in 8mA reset current for RJ45 transmission transformer environment (optional, pre-shipment installation only)<\/li>\n<li>For TV Inverter transformers, 100Bin leakage classification and leakage balancing are provided.<\/li>\n<li>ALC (Automatic Location Compensation) function for MLCC (Multilayer Ceramic Electrolytic Capacitor) measurement (3252\/3302)<\/li>\n<li>Provide fixture stray capacity compensation function for transformer and inductor measurement.<\/li>\n<li>1320 DC Overlap Current Source Direct Control Power (3252\/3302)<\/li>\n<li>Large LCD display (320 x 240 dot matrix)<\/li>\n<li>Provide all kinds of standard test fixtures and special fixtures customized.<\/li>\n<li>Four-terminal test fixtures for accurate and stable measurement of DCR, inductance and turn ratio.<\/li>\n<li>Built-in comparator: 10 levels of bin sorting and counting (3252\/3302)<\/li>\n<li>Inductance measurement as leakage inductance center value for transformer applications in chargers.<\/li>\n<li>4M SRAM memory card for machine data setup and backup<\/li>\n<li>Standard RS232, HANDLER, PRINTER interface, support LCR function GPIB interface (optional)<\/li>\n<li>15 internal instrument settings to store and call<\/li>\n<\/ul>","protected":false},"featured_media":10822,"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":[3527],"product_cat":[15],"product_tag":[2917],"class_list":{"0":"post-9677","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_brand-chroma","7":"product_cat-uncategorized","8":"product_tag-2917","10":"first","11":"instock","12":"shipping-taxable","13":"product-type-simple"},"_links":{"self":[{"href":"https:\/\/ad.wbyq.cn\/en\/wp-json\/wp\/v2\/product\/9677","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=9677"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/ad.wbyq.cn\/en\/wp-json\/wp\/v2\/media\/10822"}],"wp:attachment":[{"href":"https:\/\/ad.wbyq.cn\/en\/wp-json\/wp\/v2\/media?parent=9677"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/ad.wbyq.cn\/en\/wp-json\/wp\/v2\/product_brand?post=9677"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/ad.wbyq.cn\/en\/wp-json\/wp\/v2\/product_cat?post=9677"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/ad.wbyq.cn\/en\/wp-json\/wp\/v2\/product_tag?post=9677"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
