  4. Interface Gold StandardTM Calibration Systems Controlled calibration process reduces calibration times by 50% to 90% and produces consistent calibration results Easy-to-use software reduces operator training time Fully integrated reporting functions Automatic archiving of calibration results Supports ASTM E74, ASTM E4 and ISO 7500/1, EH10002 Industry Accepted terms and calculations 0.1µV display resolution Used in over 250 calibration labs world-wide INTERFACE

  5. 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
