- Low Capacitance & Low Inductance Design
- High Accuracy 0.02%
- Suitable for Direct Current & Technical Frequencies
- Oil-Filled Design Ensures Great Long Term Stability <0.01% Over Many Years
The DCCS Series Current Shunts are calibration grade devices used for precise dc current measurements. They extend high accuracy measuremenets beyond the available limits of self-contained dc ammeters and the DCCS Current Shunts can be used as standard reference resistors.
The DCCS Current Shunts are low cost 4 terminal calibration resistors that combine high accuracy , class 0.02, long term stability and permanence of calibration in a compact unit. Constructed using carefully selected low temperature coefficient Manganin or Zeranin wire, depending on the value, and mounted to ensure mechanical stability, these current shunts will provide a cost-effective addition to any labratory or workshop.
Main Areas of Application For The DCCS Current Shunt:
- for tests of measuring bridges or electrical temperature measuring equipment
- for a laboratory setup of a Wheatsone bridge
- as shunt resistor for current measurement
- as part of standard equipment in research laboratories
