A compressor discharge transmitter is ranged 0–10 bar and the PLC input reports 12 mA during a steady test. This page owns that exact calculation job and opens the matching server-graded case rather than a generic calculator.
Follow the workflow
The lower range value is 0 and the upper range value is 10 bar. The engineering span is the difference between those values; it is not automatically zero-based.
Do this in the product
Open the registered Gauge pressure transmitter case so the grader—not the browser copy—owns the expected result.
Open the exerciseSubtract the 4 mA live zero from 12 mA, then divide by the 16 mA measurement span. Keep enough precision until the engineering conversion is complete.
Do this in the product
Calculate the fraction separately before typing the final engineering value into the lab.
Open the exerciseMultiply percent span by the configured engineering span, then add 0 bar. The registered expected result is 5 bar within ±0.01 bar.
Do this in the product
Submit the value and inspect the range, live-zero and tolerance checks returned by the server.
Open the exerciseA calculation mismatch can come from signal measurement, transmitter configuration, PLC card range, program scaling or unit conversion. Preserve the measured current, range, result and timestamp before changing any layer.
Do this in the product
Create an account to retain the attempt, then use a paid workspace to compare cases, keep full history and assign the exercise.
Open the exerciseCore concepts
The simulator creates a repeatable result; these concepts make that result transferable to real vendor software and supervised practical work.
Four milliamps represents the lower engineering value, leaving near-zero current available as fault evidence.
For this Gauge pressure transmitter, the span is 10 bar.
The case records the input, expected value, units and ±0.01 bar acceptance statement instead of returning an unexplained number.

Direct answer
The learner can calculate and inject known points, distinguish range from calibration evidence and trace an incorrect pressure to the first mismatched layer.
Written for instrumentation and PLC learners converting a 0–10 bar measurement into loop current or voltage, raw counts, engineering units, alarms and diagnostic quality.
Lower and upper range values, engineering unit, output standard, live-zero behavior, loop power, input range, raw-count endpoints, accuracy, damping, alarm and safe work state.
Applied pressure through sensor, transmitter conversion, loop signal, input conversion, raw value, PLC scaling, displayed pressure, alarm and independent reference.
Zero, midpoint and span values remain within declared tolerance and the displayed unit and range match the instrument contract.
Under-range, over-range, open loop, short, reversed polarity, wrong input mode, offset, drift, damping, stale value and restored communication.
A pressure reference, sensor, transmitter range, loop, input, raw-count, scaling, unit, alarm, quality or display mismatch.
The loop calibrated and commissioned with approved equipment, traceable references, target cards and site procedures.
Map the transmitter’s output endpoints and the input card’s raw endpoints linearly to 0 and 10 bar, then verify several known points.
For an ideal linear range it represents 50% of span, or 5 bar, before considering calibration tolerance and configured range.
