PRS

  • Product No:PRS
  • Manufacturer:IET LABS, Inc. 

Description:

The PRS-300 dramatically improves the most important aspects of the older manual resistance decades. It introduces an advanced algorithm to create a easy to use programmable resistor with 30% improved accuracy and 1000 times better resolution than traditional laboratory decade boxes and RTD Simulators.
The PRS-300 was designed with the right mix of features for to be efficient for both manual and automated application in both laboratory and production environments.  With its wide range the PRS-300 was designed to replace multiple decade boxes and reduce test time.  
With its industry leading 5 year warranty all aspects of the PRS-300 focus on reliability, reduced ownership costs and simplicity out of the box.  
The simple user interface  makes PRS-300 well suited for high accuracy requirements for both manual and automated applications such as RTD simulation, DMM calibration, circuit trimming, and load testing.


Features:

• Basic accuracy of 70 ppm
• Resistance range from 100 mΩ to 20 MΩ
• Virtually automatic self-calibration
• No zero subtraction required - as is necessary with other manual or programmable units
• Use for RTD applications is straightforward without and "subtractions"
• Built-in RTD tables for PT100 and PT1000
  May be used with 2 or 4 terminals

• User friendly software
• Reduced number of components and resistors for longer term reliability
• Standard USB interface for computer control
• Optional IEEE-488.2 and ethernet interfaces
• LabView drivers for control, adjustment, and using the Keysight 3458A or Fluke 8508A; no need for manual adjustment

  • User interface: Numeric keypad to enter resistance value with digital display.

  • Accuracy: ±(70 ppm + 1 mΩ) 2 and 4 Terminal at 23°C ±5°C

  • Minimum setting: 0.1 Ω

  • Resolution: 1 μΩ or 6 digits

  • Range: 0.1 Ω- 20 MΩ

  • Stability: ±50 ppm/year

  • Thermal emf: < 15 μV

  • Maximum Load: 2 A, 200 V (peak), 0.5 W whichever applies first

  • Resistors: Precision wire-wound and metal foil

  • RTD Tables: 9 RTD tables can be entered into memory to allow user selection of temperature and the correct value of resistance will automatically be programmed. PT-100 and PT-1000 tables for both Fahrenheit and Celsius are pre-programmed into memory locations 1 to 4.

  • Adjustment: Automatic adjustment procedure utilizing a high precision DMM eliminates the requirement for manual trimming of resistors.
