Final Functional Test Load with functional test rig connected load of 6 kW: a worked example in wearable medical sensors

This worked example runs the final functional test load numbers for a tougher week than the baseline: functional test rig connected load of 6 kW instead of the typical 12 kW. Estimate final functional test load for wearable medical sensors using production-ready inputs so teams can budget energy cost, compare equipment settings, or include electricity in the quote.

The inputs for this scenario

  • Functional test rig connected load: 6 kW (the input this scenario stresses; the baseline uses 12)
  • Test rig runtime: 8 hr (held at the documented default)
  • Blended electricity rate: 0.12 $ / kWh (held at the documented default)
  • Sensors tested during runtime: 1,000 units (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Total final functional test load energy cost = final functional test load connected load × final functional test load runtime × blended electricity rate.
  • Final functional test load energy used works out to 48 kWh at these inputs, and this is the headline figure for the scenario.
  • Total final functional test load energy cost works out to 5.76 $ at these inputs.
  • Energy cost per kWh works out to 0.01 $ / piece at these inputs.
  • Hourly final functional test load energy cost works out to 0.72 $ / hr at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where functional test rig connected load sits at 12 kW and the headline result is 96 kWh, this scenario comes in 50% below the baseline at 48 kWh.
  • Use it when allocating test-station energy into unit cost, or comparing the operating cost of a longer test sequence against a shorter one. A result at this level usually justifies acting on the stressed input before touching anything else, because every other figure in the table is downstream of it.

Results at a glance

  • Final functional test load energy used: 48 kWh (headline result)
