Product Highlights

The TRS1 is a unit designed to be used with ratio meters as a high accuracy reference ratio standard. This unique standard is able to provide ratios in both step down (traditional ratio test instruments) and step up (Biddle Hand Crank TTR) test modes. The standard is designed for use as a laboratory calibration standard, or as a portable check standard for field ratio and phase verification of any ratio instrument.

The TRS1 can be used with any single phase and three phase ratio meter. When testing three phase ratio meters with the TRS1, one uses the instrument’s single phase excitation for testing. Alternatively, three TRS1s can be combined to test a Wye-Wye configuration using the ratio meters three phase excitation test method.

  • Step Down & Step Up Ratio
  • Includes ratios from 1 to 2048 step down, and 1 to 32 step up
  • High Accuracy 0.01%
  • Rugged Design for Field Use
  • Designed to be used with large test clips or banana jack inputs
  • Four-terminal Kelvin - no lead compensation required
  • Universal standard for use with all ratio meters
