Standard Resistance Standards and Decades Datasheets

The A40 Series consists of 12 shunts rated from 10 mA up to 5A. The A40A shunts add 10A and 20A ranges. The A40/A40A allows you to make ac/dc current transfer measurements with the 792A Transfer Standard or 5790A Measurement Standard. Special cables are required. * AC current transfer measurements...[See More]
