The ANYLOAD AN404 Series is a portable load cell tester designed for comprehensive bridge resistance, insulation, and sensitivity measurements in laboratory and field environments. This portable instrument measures bridge resistance, insulation resistance (500-10,000 M\u03a9), input and output resistances, and zero balance with high precision, making it essential for load cell calibration, verification, and troubleshooting.<\/p>","protected":false},"excerpt":{"rendered":"
The ANYLOAD AN404 Load Cell Tester is a precision instrument designed for comprehensive load cell diagnostics and validation in the lab or field. Featuring a 7-inch color touch screen display and advanced synchronous digital ratio technology, the AN404 delivers high accuracy measurements of \u00b10.5\u03a9 below 2000\u03a9 and \u00b11\u03a9 above 2000\u03a9, with a total resistance measurement range of 0 to 4000\u03a9. The instrument simultaneously measures bridge resistance, insulation, input and output resistances, and zero balance \u2014 making it essential for load cell manufacturers, system integrators, and field technicians who require quick, reliable diagnostics.<\/p>\n
\nThe AN404 Series combines robust functionality with user-friendly operation through per-channel calibration, automatic settings retention after power loss, and configurable sensitivity decimal places (4\u20135 positions). Its RS-232 interface and Modbus Protocol support enable seamless integration into automated testing labs and data logging systems. Insulation testing capability reaches 500 to 10,000 M\u03a9 at 100V (\u00b15%), providing thorough electrical safety validation for load cells before deployment in critical applications.<\/p>\n
\nAvailable in four international plug variants (Type-B, Type-F, Type-I, and Type-G), the AN404 is built for global distribution and regulatory compliance. Weighing approximately 4.48 kg with a power supply of 100\u2013240 VAC (50\u201360 Hz), it operates as a standalone portable test station or integrates into larger scale production and QA environments. The AN404 is indispensable for quality assurance in weighing industries, load cell manufacturing, sensor validation, and any application requiring certified load cell performance confirmation.<\/p>\n<\/p><\/div>\n
