The 1000 series of standards are highly stable low value resistors designed for laboratory or on-site calibration use. They may be used as low resistance standards or as semi-precision shunts.
Rated accuracy is for full current. Each standard is calibrated at four current levels, for complete characterization. Up to 150% current may be applied for brief periods without damage.
Their low temperature and power coefficients allow them to be used in a variety of environments without loss of accuracy. They are not significantly affected by changes in barometric pressure or relative humidity, and are will withstand moderate vibration and shock. They feature low reactance, allowing their use as both dc or ac standards.
All models are housed in a rugged, die-cast aluminum case. Internal shock-absorbing construction reduces the possibility of shifts in value due to vibration or impact. Connections are made via gold plated five-way binding posts which accept bare wire, spade lugs or banana jacks.
All models are supplied with NIST traceable calibration data, including temperature characterization..
All models are available with an optional temperature sensor bonded to the resistance element. Decade values are standard; other values are available.
