GX-6000 Operator’s Manual
Chapter 3: Operation • 35
Measuring Mode, Normal Operation
When the GX-6000 completes its startup sequence, it is in Measuring Mode. In Measuring
Mode the GX-6000 continuously monitors the sampled atmosphere and displays the gas
concentrations present for its target gases. In a low-light environment, press and release
any button to turn on the display backlight. See “Updating the Backlight Time Setting
(BACK LIGHT TIME)” on page 148 to program backlight duration. If
CONFIRMATION
is set to
ON
in the Maintenance Mode menu (see “Updating the
Confirmation Alert Setting (CONFIRMATION)” on page 150), the GX-6000 beeps
periodically to confirm that it’s operating.
Monitoring an Area
1 . Start up the GX-6000 as described above in “Start Up” on page 25. 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 110 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 43.
