The phrase "due to operator error" is correct and usable in written English.
You can use it to refer to a mistake made by a person who was responsible for the operation of a machine, system, or process. For example, "The power outage was due to operator error, not a mechanical malfunction."
In addition, companies benefit from virtual elimination of downtime due to operator error, significantly improving the quality of their operations.
According to an internal NSA audit report detailing the incidents in the first quarter of 2012, the majority occurred due to "operator error", usually from failure to follow procedures, typographical errors, insufficient research information, or workload issues.
An inaccurate blood glucose value, due to operator error or an inaccurate glucose meter, will cause a calibration error (5).
Machines cannot identify an unsatisfactory scan acquisition due to operator error, insufficient scan speed or patient movement.
Initial invalid results were largely due to insufficient DNA in two batches of tests which may be due to operator error in the extraction process.
In addition to these flow related defects, other geometry related defects also exist, such as lack of penetration and lack of joining, which mainly occur due to operator errors.
This could reduce the variability in temperature measurements due to operator errors, e.g. wrong choice of skin emissivity or incorrect measurement of reflection temperature [ 70].
The time accuracy of the common solution approach is shown, both analytically and numerically, to be limited to first order due to operator splitting errors, low-order time integration of the remap terms, and other postulated first-order errors, even if the Lagrange step is second-order accurate in time.
The limited sensitivity of the Mantoux among culture-positive children (49%) may be due, in part, to operator error in the intradermal administration of tuberculin, as well as the suppressive effect of TB disease on cell-mediated immunity[4].
"Nine times out of ten, lab accidents are caused by operator error," observes Johnson--and operator error, in turn, is often due to operator fatigue, inattention, or haste.
Operator-splitting errors for both the standard two-step and alternating two-step methods are presented, the latter approach being popular as a way to reduce errors due to operator splitting.
