Gold StandardTM Calibration System Options GS-USB: Provides USB interface for HRBSC, SCB1, DA-101 and HL4IO instrument boards includes internal power supply, cooling fan and USB cable. SCB1: 20 bit instrument board provides signal conditioning for the Gold StandardTM System. Available in single or dual channel versions. HRBSC: High-resolution 22 bit instrument board increases accuracy over the SCB1. DA-101: Digital to analog board for generating command signal for system control. Provides setpoint signal for servo controlled hydraulic force testing. HL4IO: High level 4-channel input board allows calibration of ±5 and ±10 VDC output transducers and includes all features of the DA-101. Load Cell Simulator: mV/V transfer standards are used to calibrate the Gold StandardTM system, and for setting up and testing load cell readout devices. CX-0404 - specifically designed for instrument substitution testing as per ASTM E74. Desktop, laptop or portable PC: Contact factory for currently available configurations. Gold StandardTM or Platinum StandardTM load cells as required. INTERFACE

Why use a simulator or mV/V Standard ? Calibrate Indicator or Signal Conditioner periodically Daily sanity check on measurements Establish true zero Check cables 11
Model CX Standard 6 digit calibration 10 ppm uncertainty 12
Shunt Calibration Technique of unbalancing bridge with external shunt resistor Less Expensive OK for medium-accuracy work Affected by preload, temperature, bridge resistance drift, cable length 13
Measurement Uncertainty Model, Calibrating Load Cell by Comparison 16
Uncertainty Components CNS = Cal of Standard Transducer by NIST DS = Drift in Standard since last cal PS = Creep in Standard Transducer TS = Temperature effect on output of Standard RHF= Nonreproducibility of frame, load string CH = Calibration of HRBSC Instrument DH = Drift in HRBSC since last cal TH = Temperature effect on HRBSC Instrument LH = Nonlinearity of HRBSC Instrument NH = Noise of HRBSC Instrument 17
CH Uncertainty in calibration of HRBSC (rectangular distribution) Source of Uncertainty Type Uncertainty (%RDG) CCX = Calibration of CX-0610 B 0.0008 DCX = Drift in transfer function of CX-0610 between calibrations B 0.0010 TCX = Temperature effect on CX-0610 B 0.0054 NCX = Noise of the HRBSC instrument during calibration with the CX-0610 B 0.0003 ------------ Combined (Root Sum of Squares) 0.0056 18
