Description: 1. The Julie Research Labs DMR-104 1 Kohm Step Precision Resistance Standard is a unit that consists of twelve (12) ultra-precision resistors having nominal values of 1 Kohms each. The ultra-precision resistors are designed for high-accuracy low-resistance measurement applications. All resistors in this unit have an absolute accuracy to within ±0.0015%. 2. It is constructed with Manganin, a trademarked name for an alloy typically consisting of 84.2% copper, 12.1% manganese, and 3.7% nickel. Manganin is used to manufacture resistors because of its virtually zero temperature coefficient of resistance value and long-term stability. 3. The accuracy is attained through developed methods, which permit the manufacture of extremely accurate and stable resistors. Special design techniques were used to minimize temperature coefficients, the effects of dissipation, and electrical and thermal induced transients. Compensation is provided as well for differential expansions and winding strains. 4. The following are key details of the unit: Product OverviewTotal number of individual resistors: Twelve (12)Absolute accuracy: Within ±15 ppm (±0.0015%)Stability: Less than ±15 ppm (±0.0015%) absolute and ±5 ppm (±0.005%) relative (resistor to resistor)Temperature coefficient: Within ±5 ppm/°C absolute and ±2 ppm/°C relativeSelf-heating coefficient of resistors: 10 ppm/watt (0.001%/watt)Thermal transients: Less than 5 ppm (0.005%) at rated currentVoltage maximum: 200 volts between terminals of a resistorConstruction: Hermetically sealed in a metal case, which provides electrostatic shielding and isolation from environmental effects other than temperature, and filled with moisture free oilFeatures · High Precision: Ensures reliable and accurate resistance measurements · Long-Term Stability: Maintains performance over time with minimal drift · Robust Construction: Designed to withstand various environmental conditions Applications · Ideal for use in calibration labs, research institutions, and industries requiring precise resistance measurements · Commonly used in metrology, electrical testing, and quality control processes------------------------------------------------------------------------------------------------------------------------------------------------------------------------------Payments· Acceptable payment for equipment is through PayPal, Wire Transfer in US Dollars, or by Company/Personal Check.· If the purchase is paid for with a check, the equipment will not ship until the check clears the seller’s financial banking institution.· Customers who want to claim tax exemptions must send a tax exemption form to eBay. eBay collects all sales taxes, as we have no control over this process.Shipping (Domestic) · The packing process is photographed for your security and ours.
