GX-6000 Operator’s Manual Measuring Mode, Normal Operation • 30
Monitoring an Area
1 . Start up the GX-6000 as described above in “Start Up” on page 19. It is
now in Measuring Mode.
2 . Take the GX-6000 to the monitoring area.
Put the probe tip in the area to be monitored.
NOTE: If the particle filter or hydrophobic filter become dirty or clogged,
replace them. If water enters the probe, dry out or replace the
particle filter (if installed) and shake any water out of the probe and
off of the hydrophobic filter. If you notice that water has entered the
flow system through the probe, replace the probe’s hydrophobic
filter. See “Replacing the Probe’s Particle Filter and Hydrophobic
Filter Disk” on page 115 for instructions to replace the particle filter
and the hydrophobic filter.
3 . Wait 10 - 15 seconds and observe the display for gas readings. If a
reading is observed, allow the reading to stabilize to determine the gas
concentrations present.
NOTE: Response time increases with the length of the sample hose. Long
sample hoses will require more time to show a response at the
GX-6000. The maximum sample hose length recommended for the
GX-6000 is 50 feet. Consult RKI Instruments, Inc. for longer
sample hose lengths.
4 . If a gas alarm occurs, take appropriate action. See “Responding to
Alarms” on page 38.
