1000 series Low Resistance Standards
- HIGH STABILITY
- HIGH IMMUNITY FROM ENVIRONMENTAL EFFECTS
- FOR USE IN AIR - NO OIL BATH NEEDED
- 1 Ω AT 1 A TO 1 μΩ AT 100 A
- IMPROVED SPECIFICATIONS
The 1000 series of standards are highly stable low value resistors designed for laboratory or on-site calibration use.
Each standard is calibrated at several 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.
All resistance standards include ISO 17025 Accredited calibration, as well as temperature characterization.
1 and 10 micro-ohm standards include a RTD temperature sensor bonded to the element. This is optional on other models. Decade values are standard; other values are available.
