III.5.6.2.The oil temperature sensor or engine temperature:
Select, according to the mode chosen:

With the 85XX mode or « WIRED » mode, it is necessary to insert
the probe into the gauge. Do not insert it too deep. Adjust the probe
length in order for it to soak into the oil when the sealing cone acts as a
stopper.

With CAP13XX, point out one of the engine hot area

With CAP4XXX, the engine temperature is automatically retrieved
by the vehicle embedded computer.
After inserting the probe and the sensors, with the engine still running, it is necessary to notify
the opacimeter that all is ready. To do this, press the OK key to move on to the following phase.
III.5.7.Preliminary checks
Before undertaking any measurement, the operator must satisfy himself that the engine is
operating correctly. Opacity measurement being a rather demanding procedure for the engines, it
is imperative that this step be carefully followed to avoid engine damage and to obtain a valid
opacity measurement.
The following points are to be observed:

The vehicle exhaust line must be gas-tight. This check can be carried out by
partially blocking the exhaust while the engine is at idle. No leak must be
observed.

The gearbox must be in neutral, with the clutch engaged, for vehicles with
manual or semi-automatic transmissions; the selector should be in neutral
for vehicles with automatic transmissions or in accordance with the
instructions of the vehicle manufacturer.

Accessories and optional equipment that influence the engine speed at idle
must not be activated, barring manufacturer’s instructions or regulation to
the contrary.

The engine must be at normal operating temperature
