Instrumentation Amplifier WGI-400A

• 3 sensitivity registration modes (Actual load calibration, sensitivity-registered calibration, numerical value-registered calibration)
  
• Selectable 4 high/low limit patterns in memory
  
• Level test with desired set-value

The WGI-400A is a compact Instrumentation Amplifier which has basic functions required for measurement in combination with strain-gage transducers.
