Uniform 0.01% Reading Accuracy Across Full Current and Voltage Ranges<\/h3><p>Unlike most products that have higher error in the low range (1A\u2013200A) due to %RG design, the PIU2000D delivers \u00b10.01% reading accuracy across the full range\u20141A to 2000A for current and 1V to 2000V for voltage. This ensures equally reliable testing for both low-current and high-voltage scenarios, allowing a single unit to handle the calibration of battery cell, module, and PACK charge-discharge testers.<\/p><h3>2. Dual-Mode: Feed-Through and Direct-Input<\/h3><p>Features a high-current feed-through mode (with a large 70 mm aperture) that employs isolated measurement for high currents, alongside a direct-input mode for low currents that guarantees the accuracy of weak signals. This multi-purpose functionality reduces the user&#8217;s initial investment costs.<\/p><h3>3. Integrated Voltage, Current, and Power Measurement<\/h3><p>Simultaneously measures voltage, current, and power\u2014a capability superior to pure ammeter-based solutions.

One Device Covers All Specifications: Significantly Reduced Costs<\/h3><p><strong>Industry Status Quo: <\/strong>Third-party testing agencies and manufacturers often deal with a wide variety of equipment specifications and models requiring testing. Different specifications of charge-discharge testers typically require matching with various calibration devices, resulting in substantial hardware asset investments and high management costs.<\/p><p><strong>Hangzhi Solution:<\/strong> Multi-purpose functionality in a single unit. The PIU2000D covers a current range of 1A to 2000A and a voltage range of 1V to 2000V, maintaining a full-scale reading accuracy of \u00b10.01%. A single device is compatible with the calibration of virtually all charge-discharge tester specifications, significantly reducing procurement and maintenance costs.<\/p><h3>2. Consistent \u00b10.01% Reading Accuracy Across the Full Range: Precision Even at Low Currents<\/h3><p><strong>Industry Status Quo:<\/strong> Traditional equipment performs adequately in the high-current range; however, in the low-current range (1A\u2013200A), they often rely on &#8220;range accuracy&#8221; (%RG) specifications. This leads to larger error margins and fails to meet the high-precision requirements for battery cell charge-discharge testers.<\/p><p><strong>Hangzhi Solution:<\/strong> The PIU2000D maintains a reading accuracy of \u00b10.01% across its entire operating range. Whether measuring 1A or 2000A, the precision remains consistent, ensuring reliable multi-purpose utility from a single device.<\/p><h3>3. Breaking Through the Bottleneck of High-Voltage Testing (&gt;1000V)<\/h3><p><strong>Industry Status Quo:<\/strong> Traditional multimeters are limited to measuring voltages up to 1000V. However, modern energy storage battery testing often involves voltages approaching 2000V; consequently, traditional multimeters are no longer capable of meeting these new testing demands.<\/p><p><strong>Hangzhi Solution:<\/strong> The PIU2000D offers a full-scale voltage range of 1V to 2000V with a reading accuracy of \u00b10.01%. It effectively meets the high-voltage testing requirements for energy storage batteries, providing a practical solution to a critical industry pain point.<\/p><h3>4. Integrated Design for Simplified Operation: Enhanced Efficiency and Stability<\/h3><p><strong>Industry Status Quo:<\/strong> The traditional &#8220;shunt + multimeter&#8221; configuration offers a precision level of only 0.1 to 0.5. Furthermore, it requires manual data conversion, is prone to errors introduced by contact resistance in wiring, and suffers from stability issues caused by temperature drift\u2014all of which result in low operational efficiency.<\/p><p><strong>Hangzhi Solution:<\/strong> PIU2000D. Features 0.01-grade direct-reading accuracy, eliminating the need for external shunts or cumbersome calculations while effectively nullifying the influence of wiring resistance. It supports both cable-through and series connection methods and offers multiple communication interfaces\u2014with RS232 and RS485 included as standard, and a CAN interface available as an option. Calibration results can be directly imported into test reports, thereby exponentially boosting operational efficiency and facilitating seamless system integration and automated testing.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-c61e7e7 elementor-widget elementor-widget-text-editor\" data-id=\"c61e7e7\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p>The PIU2000D is specifically designed for the calibration of current charge-discharge testers.<\/p><p>In the field of battery testing and metrology, the transformative impact of the PIU2000D can be summarized in a single statement:<\/p><p>A single Hangzhi PIU2000D unit handles the calibration of battery charge-discharge testers across all specifications and models.<\/p><p>Beyond simply enhancing data credibility, it delivers:<\/p><ul><li>A substantial increase in calibration efficiency<\/li><li>A significant reduction in testing costs<\/li><li>Comprehensive coverage of both laboratory and field applications<\/li><\/ul><p>The PIU2000D serves as a pivotal tool for battery manufacturers, metrology institutions, testing laboratories, and similar entities seeking to enhance their competitive edge.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<section class=\"elementor-section elementor-inner-section elementor-element elementor-element-583bd40 elementor-section-boxed elementor-section-height-default elementor-section-height-default\" data-id=\"583bd40\" data-element_type=\"section\" data-e-type=\"section\">\n\t\t\t\t\t\t<div class=\"elementor-container elementor-column-gap-default\">\n\t\t\t\t\t<div class=\"elementor-column elementor-col-50 elementor-inner-column elementor-element elementor-element-1661e6d\" data-id=\"1661e6d\" data-element_type=\"column\" data-e-type=\"column\" data-settings=\"{&quot;background_background&quot;:&quot;classic&quot;}\">\n\t\t\t<div class=\"elementor-widget-wrap elementor-element-populated\">\n\t\t\t\t\t\t<div class=\"elementor-element elementor-element-d46289d elementor-widget__width-initial elementor-widget elementor-widget-heading\" data-id=\"d46289d\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<h2 class=\"elementor-heading-title elementor-size-default\">Over Hangzhi<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t<div class=\"elementor-column elementor-col-50 elementor-inner-column elementor-element elementor-element-c91af99\" data-id=\"c91af99\" data-element_type=\"column\" data-e-type=\"column\">\n\t\t\t<div class=\"elementor-widget-wrap\">\n\t\t\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<div class=\"elementor-element elementor-element-adbe105 elementor-widget elementor-widget-text-editor\" data-id=\"adbe105\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p><a href=\"https:\/\/www.hangzhiprecision.com\/nl\/\"><strong>Shenzhen Hangzhi Precision Electronics Co., Ltd.<\/strong><\/a> is een technologisch toonaangevend bedrijf dat zich toelegt op onderzoek en ontwikkeling, productie, verkoop en klantspecifieke oplossingen van zeer nauwkeurige stroomsensoren, spanningssensoren en zeer nauwkeurige elektrische meetinstrumenten.
