3.2 CARES AND NOTES
- During tests be sure that RPM probe cord is not passing close to the other
cylinders or to the coil to avoid electronic noises.
- Be sure that arrow on the clamp of RPM probe is in the right direction (to the
cylinder).
- Sometimes RPM probe cannot measure RPM. It depends on very special kind of
plug cords strongly shielded. In such cases write manually RPM on printed report
as read from the engine speed indicator.
- Before every test, verify that condensate filter is not full of water to avoid an
unpredictable stop of the test itself for a possible automatic condensate drainage.
In this condition the analyzer must be switched OFF. The water must be removed
from the filter before powering up the device again.
- The internal porous septum of condensate filter must be cleaned periodically to
avoid flow missing. To do this first be sure that pump is off, then remove the small
silicone hose from the drainage valve pinchcock and unscrew carefully but firmly
the plastic glass of filter; the internal septum can be removed by acting on the
screw placed below it. The porous septum can be cleaned by bathing it with
gasoline or trichloroethylene. After a while, blow in compressed air and put it back
in its place. Finally screw the plastic glass, being sure that the o-ring is well
positioned, and put the small silicone hose in the valve pinchcock.
- Replace periodically the paper particle filter.
- If the "Err1"....”Err5” messages appears on FUNCTION display verify that:
- the gas tip and the hose are not blocked up or full of condensate;
- the condensate filter is not full;
- the particle filter is not damaged or blocked up;
- the gas exhaust of instrument is not blocked up. Note that in this case, after
having removed the block, it takes about 5 min. to restore O2 measurement
stability because of possible pneumatic stress of Oxygen sensor.
- for more information see the Troubleshooting chapter on this manual.
- It is advisable to remove, almost every day, water from gas hose by blowing in
compressed air in the direction of particle filter arrow (from the tip to the
instrument) obviously after having removed the hose from the instrument.
