RKI Instruments Gas Tracer 10,000 ppm - Manual (Page 34)

27 • Leak Testing 10,000 ppm Gas Tracer Operator’s Manual
Setting the Display Range Value
The Gas Tracer Leak Check Mode has 4 display range ppm values to
choose from: 1000 ppm, 2000 ppm, 4000 ppm, and 9990 ppm.
NOTE: The Gas Tracer is always detecting combustible gas up to 9990
ppm. The display range value is only adjusting what part of
the detection range is displayed on the LCD.
To change the display range value:
1. While in Leak Check Mode, press and release the DISPLAY (ADJ)
button. The display range value displayed along the bottom of the
screen will change.
Continue to press and release the DISPLAY (ADJ) button until the
desired display range value is displayed.
2. The unit is now operating with the selected display range.
Locating a Leak
1. Start up the Gas Tracer as described above in “Turning On the Gas
Tracer” on page 16.
2. Move the probe tip or tapered nozzle tip back and forth along the
area where a leak is suspected.
3. Observe the display reading. If the gas level increases, the
numerical reading will increase, the bar graph level will increase,
and the beeping and buzzer pulsing frequency will increase.
4. Your gas reading may exceed your display range. For a description,
see the following section.
5. Use the increasing and decreasing of the reading to locate the leak
point.
Overscale Condition
The Gas Tracer may experience an overscale condition while
operating in Leak Check Mode.
