Chap. I - Gas Analyser
1. INTRODUCTION
• The gas analyser is a PC based four (plus optional NOx) gas analyser.
• The gas analyser is intended for the maintenance and inspection of spark ignition engines.
• Gas data is transmitted from the gas analyser to the PC (or Laptop) for processing and printing.
• The gas analyser is part of the modular Multi-Diag system.
2. SAFETY PRECAUTIONS
a) The apparatus meets requirements for operation according to the EN 61010-1.
b) The device shall be powered using only the power supply provided.
c) Removing covers from the apparatus is not allowed, as this would cause an electric shock risk.
d) The device must be operated higher than the withdrawal probe inlet due to the risk of the analyser
becoming filled with a large quantity of water, coming from condensate in the exhaust system.
e) The device is intended for operation in the vertical position only. It should in no case be tilted
even when switched off. The reason is the dangeur that moisture condensed within the rough filter F1
can flood the sensitive elements within the analyser.
f) For emission control working sites and for service working sites, relevant safety regulations should be
applied. The operator must organise appropriate safety training courses for service staff of the measuring
apparatus. This can include training for working on vehicles while the engine is running.
Therefore, safety precautions must be observed according to the manufacturers of the car and of the
engine, that are valid for testing the engine while it is running. Sufficient ventilation must be provided for
exhaust fumes and outlet gases from the analyser.
g) The device should be protected against ambient water in any form (rain, sprayed water, etc.)
