Mixed-fleet stations need more than two instruments. They need one clear workflow that sends each vehicle to the correct procedure while protecting traceability and throughput.
Route vehicles by procedure
Use vehicle identity, fuel type, category and applicable rule to select the test sequence before the operator begins measurement.
Define how hybrids, alternative fuels, unavailable data and visibly unsafe vehicles are handled.
Share infrastructure without mixing evidence
Power, ventilation, network and operator work areas may be shared, but each test must retain its own zero, calibration, environmental and result records.
Place probes, hoses and optical heads so that cross-contamination and vehicle movement do not create avoidable delays.
Standardize exceptions and retests
Document abort conditions, invalid measurements, equipment alarms and authorization for retests.
The final report should identify the procedure, instrument, time, operator and any approved exception.
What should the project team confirm?
- Vehicle identity and fuel
- Procedure decision rules
- Instrument readiness
- Probe and work-area layout
- Calibration traceability
- Abort and retest rules
- Final report fields
Share the applicable procedure, vehicle scope and operating environment.
