1、Oil Immersion Provides Thermal Isolation All standards, except the 100 k/step standard, are immersed in a mineral oil bath. Oil immersion provides thermal isolation to minimize the effects of ambient temperature variations. This means maximum short-term thermal stability for the standards. The SR103

2、0 also exhibits superior long- term stability (20 ppm of nominal for six months; 35 ppm typical for two years; 50 ppm typical for five years). This gives you longer mean time between calibrations, increasing your calibration throughput. As an added benefit, the oil speeds the dissipation of heat cre

3、ated in the resistors during calibration. This heat dissipation further contributes to the stability of the standards. Gaskets seal the SR1030 to keep the work surface and measuring contacts clean. The gaskets also minimize oil aging and contamination to lengthen the time between oil changes. Since

4、the 100 k standard can be measured at much lower bridge power than the lower value standards, it is not necessary to immerse the standard in oil. However, this standard still benefits from the thermal lagging effects Extremely Accurate and Stable The Model SR1030 provides the part-per-million (ppm)
