Operation
The Gas Tracer has three operating modes within Normal Mode:
Measuring Mode, Display Mode, and Calibration Mode. This section
describes using the Gas Tracer in Measuring Mode during normal
operation.
In Measuring Mode the Gas Tracer 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 LCD Back
Light Time Setting” on page 167 to program backlight duration. If
BEEP. SET
menu item in Maintenance Mode is turned on, the Gas
Tracer beeps once every 5 minutes to confirm that it’s operating. See
“Updating the Confirmation Beep Setting” on page 160 for
instructions to update the setting.
Monitoring an Area
1. Start up the Gas Tracer as described above in “Start Up, Normal
Mode” on page 20 or “Turning On the Gas Tracer in Normal Mode
With All Modes Active”. It is now in Measuring Mode.
2. Take the Gas Tracer to the monitoring area.
If the tapered rubber nozzle is used, put the nozzle tip in the area to
be monitored.
If the hose and probe is used, put the probe tip in the area to be
monitored.
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.
