AC/DC Shunts

Precision References And Standards

Transmille offer a set of current shunts enabling measurement of current from 1mA through to 100A. Each shunt develops 0.7V at nominal full scale, enabling a wide range of multimeters to be used without loss of resolution due to changing range.

  • Shunt values for measurements between 1mA to 100A
  • AC/DC differences from 1ppm
  • Simplifies precision calibration of calibrators and current sources
  • Low inductance & capacitance flat frequency response
  • From DC to 30kHz
  • Can be used with a precision multimeter or an AC measurement standard

As multimeters add more accurate low current ranges, traditional multi-product calibrators lack the precision and noise level for accurate calibration. With the EA013 pA source adapter, calibration of these instruments becomes simple

  • Ideal for calibration of electrometer instruments
  • Source accurate current down to picoamp levels
  • Low open circuit compliance voltage
  • Safe to use on sensitive input circuits
  • Controlled directly from the calibrator front panel or via supplied software
  • Compatible with ProCal for full measurement automation
