RESISTANCE BOX & RTD SIMULATOR PRS-370 IET LABS
The PRS-370 presents a groundbreaking shift from traditional resistance decades, boasting patented advantages that revolutionize calibration processes and enhance operational efficiency.
One of its standout features is its self-adjusting capability, which surpasses the accuracy of traditional resistance standards by better than 10 ppm. This eliminates the need for individual resistance standards, providing users with consistent accuracy and reliability. Moreover, the PRS-370 ensures that the right resistance standard is always available for calibrating new instruments, streamlining calibration procedures and minimizing downtime.
A key innovation lies in its single-button press adjustment, a stark departure from the manual trimming or inputting of resistor calibration values required by conventional systems. This intuitive interface saves significant time, making calibration processes more efficient and user-friendly.
Functionally, the PRS-370 serves as a Self-Adjusting Programmable Resistance Substituter, seamlessly integrating with 8.5 digit DMMs such as the Fluke 8508A, 8588A1, or the Keysight 3458A via the IEEE-488 interface. It transforms into a short-term stable variable resistance standard, optimizing accuracy to nominal resistance values with exceptional precision, typically better than 10 ppm.
The device’s design facilitates seamless connectivity, utilizing both front and rear binding posts to enable simultaneous connection of the Device Under Test (DUT) and the DMM. After the DMM measures the source resistance via the rear binding posts, the source resistance is then switched to the front binding posts, ensuring smooth operation.
The PRS-370’s user interface is a marvel of modern technology, featuring a large color capacitive touchscreen that provides rapid response times and exceptional clarity. Even under challenging lighting conditions, the display remains highly legible, featuring large fonts and user-friendly menus. Softkeys and a numeric keypad further enhance usability, offering alternative navigation options.
Moreover, the PRS-370 prioritizes reliability and longevity, utilizing high-quality components such as low resistance, low thermal emf relays with gold-clad silver-alloy contacts. These components minimize contact resistance and ensure consistency and repeatability over extended usage.
With a comprehensive five-year warranty, the PRS-370 underscores its commitment to quality and customer satisfaction. Its versatility extends beyond resistance calibration, doubling as a programmable decade resistor and RTD simulator. Built-in tables for PT100 and PT1000 RTDs, along with customizable user-defined tables, make it ideal for RTD simulation applications.
The device’s AC performance is equally impressive, with minimal resistance change below 1 kHz, thanks to its low inductance wirewound and Z-foil resistors. It offers both local and remote operation via a color touch screen and numeric keypad or IEEE-488 interface, providing flexibility in testing environments.
Additionally, the PRS-370 features robust cybersecurity measures, ensuring data integrity and protection. Firmware updates are restricted to authorized personnel, and a factory reset option restores the device to its default settings, erasing all user data.
In summary, the PRS-370 sets a new standard in resistance calibration technology, offering unparalleled accuracy, efficiency, and reliability. Its innovative features and user-friendly interface make it indispensable for laboratory and production environments, simplifying calibration processes and reducing test times.
