Reviewed by
  • Confirm the intended source voltage is present
  • Confirm common/reference is identified consistently
  • Confirm polarity-sensitive devices are oriented correctly
  • Confirm expected resistor values are installed
  • Confirm resistor wattage is appropriate for expected dissipation
  • Confirm no obvious shorts exist across the intended load
  • Confirm the circuit matches the latest drawing revision

If measured values differ materially from the expected values, stop and re-check the circuit before continuing.
