EAGLE 2 Operator’s Manual Leak Testing • 285
• 250 ppm increments from 10,000 ppm to 50,000 ppm
As the gas concentration increases from 0 ppm, the alarm LEDs begin to
blink in unison with the buzzer’s pulsing. The blinking/pulsing rate increases
as the gas reading increases. If desired the buzzer can be turned off in Leak
Check Mode.
In a low-light environment, press and release any of the buttons to turn on the
display backlight. See “Updating the Backlight Delay Setting” on page 119
to program backlight duration. If CONFIRMATION BEEP is turned on in the
Setup Mode menu, the EAGLE 2 beeps once every 15 minutes to confirm
that it’s operating.
Locating a Leak
1. Start up the EAGLE 2 as described above in “Start Up, Leak Check
Mode” on page 279.
2. Move the probe 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
to the right, and the beeping and buzzer pulsing frequency will
increase.
4. Use the increasing and decreasing of the reading to locate the leak
point.
5. To exit Leak Check Mode and return to the Mode Select Screen at
any time, press and hold the RANGE ▼ SHIFT button for 5
seconds.
Turning the Buzzer On and Off in Leak Check Mode
The alarm buzzer can be turned off and on when the EAGLE 2 is in Leak
Check Mode. This setting only applies to Leak Check Mode and does not
affect buzzer operation in Normal or Bar Hole Mode. The buzzer setting is
displayed in the lower left corner as BUZZER ON when the buzzer is on or
BUZZER OFF when the buzzer is off. When the EAGLE 2 is turned off or
you exit Leak Check Mode, it remembers the buzzer setting. So when the
EAGLE 2 is turned on again or you return to Leak Check Mode after
operating in Normal Mode or Bar Hole Mode, the buzzer has the same setting
it did the last time it was in Leak Check Mode.
To turn the buzzer off or on while in Leak Check Mode, press and release the
DISPLAY ADJUST NO button.
