  • Page 3: Description And Specifications

    DESCRIPTION The Model 9820 is a microprocessor-based digital indicator capable of interfacing directly to a low level strain gage load cell transducer. An internal, high gain, fully-differential amplifier and a 4 1/2 digit analog-to- digital converter combine to accurately digitize the input signal. A 5V @ 60mA or 10V @ 120mA, short circuit protected, transducer excitation supply is also provided.

  • Page 15: Calibration Instructions

    CALIBRATION INSTRUCTIONS The Interface Model 9820 can be calibrated using (2) different methods. 1. The first method uses actual or simulated ZERO and FULL SCALE (FS) inputs. Actual inputs may come from a strain gage transducer loaded with calibrated weights. Simulated inputs may come from a strain gage bridge simulator.

S3 has a 3 second delay feature to prevent inadvertent loss of calibration. Interface Inc, www.interfaceforce.com 13-60 Rev. D 9820 Installation & User Manual...
  • Page 17 Example: If the RCAL resistor supplied with the instrument creates an output equivalent to 80% of a full scale 500 pound load, set the CAL NUMBER to 400.00, 0400.0 or 00400. Interface Inc, www.interfaceforce.com 13-60 Rev. D 9820 Installation & User Manual...
