MAINTENANCE

Routine maintenance of the OdaLog® instrument is an extremely important factor affecting the reliability
of the instrument. Optimum instrument performance and reliable operation will only be achieved if a
dedicated maintenance program is followed (refer to Section 7 for sensor limitations).
To ensure reliable measurements, the OdaLog® should be checked at regular intervals with test gas as
described in the Calibration Section of the user manual.
Before you use the OdaLog®, inspect the instrument for signs of misuse or damage and cracks or missing
parts. Do not use the OdaLog® instrument if it is damaged. Please contact your closest authorised Thermo
Fisher service centre if the instrument is damaged or missing parts.
To ensure that Ex certifications and performance approvals are not invalidated, accredited workshops
should only perform any service, repair, or overhaul with full instructions and drawings from the certificate
holder. To ensure that any service, repairs, or overhaul are carried out in such a manner, it is preferable
that the OdaLog® instrument be sent to the closest authorised Thermo Fisher service centre.
Do not attempt to disassemble or perform maintenance on the OdaLog® unless instructions for that live
maintenance procedure are contained in the manual and the part is listed as a replacement. Only use
Thermo Fisher Scientific replacement parts.
The OdaLog® should be switched off when not in use and stored in a clean and dry environment, as usually
found in a normal office.
Ensure the OdaLog® exterior is kept clean with a soft damp cloth. Do not use solvents, soaps, or polishes.
It is recommended that OdaLog® instruments are returned to an authorised Thermo Fisher service centre
every six months for calibration and service.
