Problems and Solutions

Reading the wrong scale on a multi-scale asset

GageHand switches the asset to the scale AutoCalibrator specifies before the setpoint is applied - the range selection is made by the sequence, not chosen by hand at the bench.

Writing the measurement unit wrong

GageHand sets the instrument to the range and unit the sequence specifies, so the value it produces and the unit recorded against it are never a mismatched pair.

Automatic recording left turned off

Because GageHand executes the sequence AutoCalibrator sends it, the setpoints it applies are logged the same way regardless of any separate recording setting - there's nothing on the instrument side to leave switched off.

Wrong range or span configured before calibration

GageHand applies the range and span that the sequence specifies to the instrument itself, so the physical setting always matches what was defined for that job, not a value carried over from the last one.

Zero and span errors corrected separately, compounding the error

GageHand applies each zero and span setpoint as part of the same automated sequence, one after the other, so the two adjustments are made under the same conditions instead of as two separately judged steps.

Outdated manufacturer specs used as the reference

GageHand sets the calibrator to the tolerance the current specification defines, taken from the same file AutoCalibrator reads - there's no separate, possibly older, spec sheet on the bench to work from.

Wrong number of test points selected

GageHand steps through exactly the test points AutoCalibrator sends it, in the same sequence every time - there's no point where a technician decides to skip one or add an extra.

Different technicians using different methods for the same measurement

GageHand applies each setpoint exactly as AutoCalibrator sends it, so the physical adjustment is made the same way every time, not according to whatever method a given technician is used to.

Calibration setup still done by hand - setpoints, ranges, connections

GageHand changes the setpoint, range, and connections the same way, every time - it doesn't depend on "how we always do it." GageHand coordinates the calibrator side and the asset side together, so the connection is made correctly as one sequence, not as two separate judgment calls.

Equipment not verified before it goes back into service

Verification is part of the automated sequence GageHand runs - it isn't a step that depends on someone remembering to do it last.

Every manual hand-off is one more chance for a mistake

GageHand receives its setpoints directly from AutoCalibrator and reports back the same way, so there's no manual hand-off between "what should be set" and "what was actually set."
