) to avoid hazards caused by toxic, ammable, explosive or harmful
to health sample gas components!
ELECTROSTATIC DISCHARGE HAZARD
Working at internal components of electronical and electrical instruments
may cause electrostatic discharge (ESD), destroying components!
Working at open instruments is recommended at special workplaces only!
If no such workplace is available, at minimum perform the following
procedures to not destroy electronic components:
Discharge the electric charge from your body. Do this by touching a device
that is grounded electrically (e.g. instruments with earth connectors,
heating installations). This should be done periodically when working at
open instruments (especially after leaving the service site, because e.g.
walking on low conducting oors might cause additional ESD).
