The CBA-131A is a full bridge strain calibrator for static and dynamic strainmeters. The input bridge resistance can be switched between 120Ω and 350Ω, and the bridge excitation is available in both constant voltage and constant current.

Features

• Computer control possible (via RS-232C)
• Wide calibration range (±1000000×10-6 strain)
• High resolution (1/100000, 0.1×10-6 strain at the maximum)
• Excellent stability
• Usable as a standard power source of ±20V (0.1mV resolution)
  (Also usable as a constant current output)
• Geneation of dynamic output
