The Yokogawa<\/a> 2558A is a high-performance AC voltage and current calibration standard specifically designed for accurate measuring instrument calibrations. With a wide output range, impressive accuracy and intuitive operation, this instrument is ideal for both laboratory and industrial applications. The 2558A offers reliable performance and long-term stability, making it an excellent choice for professionals who depend on high-precision calibrations.<\/p>\n

Application as calibration standard<\/h3>\n

This standard is particularly suitable for calibrating AC voltmeters, ammeters and current transducers. Its long-term stability ensures that calibrations remain consistent and reliable, without frequent recalibration of the standard itself.<\/p>\n

Extended range for diverse applications<\/h3>\n

The Yokogawa 2558A supports a wide range of voltages and currents, making it flexible for use in different measurement and testing environments.
\nWith a voltage range of 1 mV to 1200 V AC and a current range of up to 60 A AC, the range of this voltage and current standard is further than most calibrators can handle. This allows it to meet the requirements of both high-voltage applications and precision measurements at low signals.<\/p>\n

Moreover, the 2558A is designed to provide minimal output impedance, ensuring low distortion and high signal purity. This makes it ideal for applications where accurate signal reproduction is crucial.<\/p>\n

Easy operation and automation<\/h3>\n

The clear front panel with a clear digital display makes it easy to adjust settings and check measurements. The 2558A is also equipped with interfaces for external control, such as IEEE-488.2 (GPIB), making it easy to integrate into automated calibration systems.<\/p>\n

Reliability and precision in one instrument<\/h3>\n

Whether for calibrations in a high-end measurement laboratory or manufacturing environments where precision is a requirement, the Yokogawa 2558A delivers the performance you need. This instrument combines accuracy, stability and ease of use in a robust housing, making it a reliable choice for calibration professionals worldwide.<\/p>\n","protected":false},"excerpt":{"rendered":"
