Dynometer operating procedure



Dynometer type: Automotive, Brake, Chassis & Suspension dynometer.

1. Turn ON  computer on control panel.
2. Turn ON pneumatic supply.
3. Ensure there is no object/obstacles from dyno entry to the roller.
4. Position car perpendicular to the roller (dyno machine).
5. Retract roller jack so car tyres touches dyno roller and can run freely.
6. Align car position by running car slowly while adjusting car position to be exact perpendicular to dyno roller.( Take note that car position is really crucial because its involving safety)
7. Setup dyno environment according to car specifications and situation:
      i- Firing cable number ( Either 1 or 2 )
     ii- NA or Forced Induction
     iii- Calculating methodology : SAE/JAS/ISO
     iv- Working temperature
     v- Maximum speed ( Currently just refer to maximum speed on your odometer )
8. Plug in timing sensor to cable plug and check response from engine to computer
                                                            or
    Plug in OBD II cable to OBD port ( usually located under the driver dashboard - varies for every                   manufacturers ) and then check response from engine to computer.
9. Plug in oil temperature sensor.
10. Plug in air/oxygen sensor.
11. Press continue on control panel computer.
12. Fix safety belt on both rear and front of vehicle - tie belt in cross sectioned and fasten tightly.
13. Run car slowly until control monitor shows " accelerate in test gear".
14. When control monitor indicate "test gear acceleration", step down fuel pedal in moderate rate until control monitor show release fuel pedal. ( Take note that when stepping down on fuel pedal, the rate need to be in computer tolerance otherwise if the rate is slower or faster the analysis will fail and control monitor will show "release fuel pedal".
15. Take analysis and reading.

* Caution: Do not brake when the car still running, let the car stop itself.
