9. Fault Finding
4000 Series analysers are sophisticated devices and any problems necessitating internal repair or adjustment
should only be undertaken by fully trained technicians.
In the absence of any CODEL trained technicians on site, it is strongly recommended that, in the event of a
fault, CODEL or its local service agent be contacted immediately with equivalent current information contained
in Tables 3 and 4.
To obtain current values for data recorded in Tables 3 and 4 follow the procedure described in Section 5.
Commissioning.
The following fault-finding charts are included to enable users to trace the possible root of a problem to assist in
providing information to CODEL or its local service agent and thereby enable a speedy response.
