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.
