APPENDIX – 1000-OHM BRIDGE COMPLETION The 2310B Signal Conditioning Amplifiers provides the capability of 1000-ohm quarter bridge operation. For this mode, the 120-ohm dummy terminal (pin B of input plug) is converted to a 1000-ohm dummy terminal by removing a solder shunt from a factory-installed precision resistor in series with the internal 120-ohm dummy gage. -
