Manual test procedure
1. Place the PoCo-Plate on the cylinder head by inserting positioning pins into the fitting bores.
2. Screw in the PoCo-Gauge into the thread for the spark plug and tighten with a torque wrench (e.g. 5 Nm).
3. Read the position of the spark plug on the scale.
Inspection of positional accuracy of the PoCo-Gauge
The PoCo-Gauge and the PoCo-Gauge Master are preset by EMUGE. For a self-check of the PoCo-Gauge the PoCo-Gauge Master is required.
The PoCo-Gauge is screwed into the PoCo-Gauge Master and tightened with a torque specifi ed by the customer. Once both lateral marking lines match, the PoCo-Gauge is set correctly.
In case of deviations, the PoCo-Gauge and PoCo-Gauge Master must be returned to EMUGE for readjustment and certification.
Automatic inspection procedure with the PoCo-Gauge 3D
During testing in a 3D measuring machine a PoCo-Gauge 3D is screwed into each spark plug thread and tightened with a specifi ed torque (recommended 5 Nm).
The angular position is measured in the combustion area. The positional angle is determined by scanning the orientation surface.
