8.3 Performing the Visual Inspections
Procedure of Visual Inspections:
• Take a log for visual inspections (Chapter 13.2 on page 267).
• Follow the instructions below for visual inspections of individual components.
• Carry out care and/or maintenance actions when test criteria are not met, and document them in the
care and/or maintenance log (Chapter 8.4 on page 171 and/or Chapter 8.6 from page 185).
• After the check and any care and/or maintenance actions, conclude the documentation of the log(s).
8.3.1 Zero Signal
• Check in the display “Status Screen” (Chapter 7.1.4 on page 91) whether the zero signal is between
0 and 0.1 FSR.
• If the signal is not within the range permitted, please contact your local partner or the Technical
Support of LAR (Chapter 15 on page 283).
• Once the test criterion is met, proceed with the next step.
8.3.2 Carrier Gas
1. Check from the “Status Screen” display (Chapter 7.5 on page 97) using the carrier gas volume flow
at the carrier gas inlet (IN) and carrier gas outlet (OUT) that the carrier gas is being transported
through the system at a rate of approx. l/h (± 5 l/h) .
2. If there is too much deviation, check the individual fittings (hose connections, etc.) or contact LAR

Danger
Risk of injury due to moving parts
During operation parts of the analyser move.
For all measures, switch the analyser to offline operation with the red button
before accessing the analyser.
Notice
If care and / or maintenance measures are taken, document them in the care
and / or maintenance record (Tab. 19, page 171 and / or
Tab. 20, page 185), as careful documentation is the prerequisite for any war-
ranty and warranty claims.
Note that after all visual inspections, care and / or maintenance, you must per-
form some tests before you start the measurements again.
