    Description the model 9834 is an enhanced performance, microprocessor-based digital indicator capable of interfacing to high-level voltage ( + 5 or + 10vdc) or current (4-20ma) output transducers. A 16-bit analog-to-digital converter accurately digitizes the input signal. A 12vdc@90ma, short circuit...

    Switch definitions (cont) increment or cal switch (s3) this switch serves two functions, depending on the present status of s1. If the instrument is in the mode selection sequence, this switch will increment the flashing digit. If the instrument is in its operating mode, s3 becomes an auto cal switc...

    Function definitions filter value (filter) {00 to 99} the 9830 uses a filter based on exponential smoothing, a digital averaging technique where the recent conversions are given more weight than the older conversions. The weighting factor is the value of (filter). The formula for the exponential fil...

    Calibration instructions the interface model 9834 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 transducer loaded with calibrated weights. Simulated inputs may come from a voltage calibrator....
