- Basic accuracy of 70 ppm
- Resistance range from 100 mΩ to 20 MΩ
- Virtually automaƟ c self-calibraƟ on
- No zero subtracƟ on required - as is necessary with other manual or programmable units
- Use for RTD applicaƟ ons is straighƞ orward without and "subtracƟ ons"
- Built-in RTD tables for PT100 and PT1000 May be used with 2 or 4 terminals
- User friendly soŌ ware
- Reduced number of components and resistors for longer term reliability
- Standard USB interface for computer control
- OpƟ onal IEEE-488.2 and ethernet interfaces
- LabView drivers for control, adjustment, and using the Keysight 3458A or Fluke 8508A; no need for manual adjustment LABVIEW DRIVERS LabView instrument drivers are avail- able for control, adjustment, and cali- bration of the PRS-300. These drivers are written based on the National Instruments instrument tem- plate, using VISA handles and standard initialize, confi gure and query functions. The drivers can be used with the USB, Ethernet or GPIB interfaces. for both manual and automated applica- tion in both laboratory and production environments With its wide range the PRS-300 was designed to replace multiple decade boxes and reduce test time. The PRS-300 can be used at an auto- mated resistance carousel with built-in EIA "preferred value" resistance tables crements or user specifi ed increments. With its industry leading 5 year war- ranty all aspects of the PRS-300 fo- cus on reliability, reduced ownership costs and simplicity out of the box. The simple user interface makes the PRS-300 well suited for high accuracy requirements for both manual and au- tomated applications such as RTD simulation, DMM calibration, circuit trimming, and load testing. NEW & ADVANCED FEATURES The PRS-300 dramatically improves the most important aspects of the older manual resistance decades. It intro- duces an advanced algorithm to create a easy to use programmable decade 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 it to be effi cient New
