   Standard       Standards provide a highly accurate standard value of resistance, capacitance, inductance, voltage, or other electrical parameter for calibration and testing.  Standards usually consist of a single, fixed-value component or several components not in the same circuit.  Some standards are available that are continuously variable; often, they incorporate a potentiometer.  Standards that have more than one component (e.g., several fixed-value resistors) have multiple posts or a rotary switch to select different resistance values. 
   Decade Box / Substituter       Decade boxes, decades or decade substituters provide highly accurate and digitally variable standard values of resistance, capacitance, inductance, or combinations of these electrical parameters for calibration and testing. Decade boxes usually consist of several components (e.g., resistors) within the same circuit. The standard resistance value is selected by varying of the number resistors in the series or parallel circuit.  
   Other       Other unlisted forms or categories.

Specifications
   Decades       The number of decades available in the decade box. 
   Search Logic:      User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.
   Capacitance Range       The capacitance range of the capacitor.  Fixed capacitors have only one value.  Variable capacitors should have a range of capacitance values. Capacitance is a measure of a capacitor's energy storage ability, given as C = K A/D, where A is the area of the electrodes, D is their separation, and K is a function of the dielectric between the electrodes. The formula yields a result in farads (F), but a farad is so large that the most commonly used values are expressed in microfarads (µf = 10-6F) or picofarads (pf = 10-12F)
   Search Logic:      User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.
   Capacitance Accuracy       The accuracy or precision of the capacitance produced by the capacitor measured as a percent of the capacitance. 
   Search Logic:      All matching products will have a value less than or equal to the specified value.
   Capacitance Resolution (per Step)       Resolution is the digital value represented by one bit in the display in a digital measure. For example, a decade box where one bit on the display represents 10 ohms as a resolution of 10 ohms (also farads/step or least significant digit <LSD>). 
   Search Logic:      User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.
   Operating / Input Voltage:       The maximum operating or input voltage of the component or instrument. 
   Search Logic:      All matching products will have a value greater than or equal to the specified value.
   Temperature Coefficient       The temperature coefficient parameter measures the rate at which the nominal resistance value changes as a function of temperature. It is expressed in parts-per million per degree Celsius (ppm/C). 
   Search Logic:      All matching products will have a value less than or equal to the specified value.
   Operating Temperature       This is the full-required range of ambient operating temperature. 
   Search Logic:      User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.
   Stability       The stability in terms of accuracy over a period of a year. 
   Search Logic:      All matching products will have a value less than or equal to the specified value.

   Your choices are...         
   NIST / National Lab Traceable       The standard's calibration can be traced to the National Institute of Technology Standards (NIST) or other national laboratory. The standard has been compared to a master standard that was checked against a NIST standard. 
   AC       The standard or decade is suitable for alternating current (AC) calibration or testing applications. 
   DC       The standard or decade is suitable for alternating current (DC) calibration or testing applications. 
   Component / OEM       The standard, source or decade is suitable for use as a precision component in a larger system or product. 
   Low Zero / Residual       The standard or decade has low values of zero, offset or residual impedance resistance, inductance or capacitance. 
   Measurement / Calibrator       In addition to providing a standard reference value, the instrument can perform precision measurements (measures or reads) for testing or calibration. 
   Computer Interface / Programmable       The decade box, voltage divider, or component has a computer interface option for programming, control, or data acquisition. 
   Variable (Continuously)       The standard or reference can provide a precise and continuously variable value such as a variable capacitor or potentiometer. 
   Rack Mount       The standard, decade box, or divider is designed or suitable for rack mounting.  Rack-mount units offer options for front and rear outputs. 
   Stand Alone / Bench       The standard, decade box, or divider is packaged in a case with binding posts. 
   Transfer / Laboratory       Transfer, primary, or laboratory-grade standards are used to compare or transfer the accuracies from NIST or national lab certified standards to working standards, sources, simulators and calibrators, or for precision meter calibration. 
   Working       Working standards are robust or rugged units for production or in-line testing and calibration. Reference or working standards are compared or verified by the transfer or laboratory standards and are then used for calibration, testing and inspection of other components, meters and instruments. 
   Other       Other proprietary, patented or unlisted features. 
   Search Logic:      All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.
