Energy use as a control signal
Compare equipment consumption with appointments to identify differences that deserve investigation, without surveillance or assumptions.
The idea: equipment leaves a measurable operating trace
A repeated treatment on the same device may produce a broadly comparable pattern of runtime and energy use. The pattern will vary with settings, maintenance, operator technique and treatment area, so it is a signal to investigate — not proof of a missing session.
Illustrative example: if a device log suggests more operating cycles than the appointment diary records, review the date and time window. The difference may come from an unrecorded treatment, testing, cleaning, a longer session or a technical issue. The data narrows the question; a person establishes the cause.
The method: deviation review in three steps
- Build a profile: record consumption or runtime for comparable treatments on the same device. Use enough observations to account for normal variation; one week is a starting sample, not a universal guarantee of accuracy.
- Compare: review measured device use against the appointments completed with that device and the treatment settings recorded that day.
- Investigate sustained differences: repeated gaps deserve a documented review. Possible explanations include unrecorded use, extended sessions, maintenance activity or an equipment fault.
✎ Practical exercise · Build an initial energy profile
- 1Confirm with the manufacturer or a qualified technician that the proposed meter is safe and suitable for the device before connecting it.
- 2For one week, record the device consumption, runtime and number of matching appointments, together with any relevant setting changes.
- 3Review differences with the team and document the explanation. Treat the result as an operating signal, not as evidence of misconduct.
