Question 1 of 34
A digital pressure transmitter has a calibrated input range of 0 to 75 PSI, and a 14-bit output (0 to 16383 “count” range). Complete the following table of values for this transmitter, assuming perfect calibration (no error).
For Counts, round down to the nearest whole value.Input Pressure (psi) Percent of Span (%) Counts (dec) Counts (hex) 0 36 62 89 95 Reveal answerInput Pressure (psi) Percent of Span (%) Counts (dec) Counts (hex) 0
