Operating Tips - CPS LS780B Manual De Usuario

• WINDY CONDITIONS:
Do not attempt to find a leak in windy areas. Even
very large leaks may be impossible to find as the
escaping gas is quickly dissipated into the
atmosphere. If necessary, fabricate a gas trap using
aluminum foil around joints or fittings or otherwise
shield the search area from the wind.
• RECOMMENDED SENSITIVITY SETTING:
When the instrument is turned ON the alarm tone
will indicate whether the instrument is in high
sensitivity or low. NOTE: The sensitivity range you
have selected is too high when the highest audible
tone is continually achieved or visual LEDs are
constantly lit. Select a lower sensitivity setting and
try again.
• EVAPORATOR FILTER HOUSING:
The presence of moisture in a leak test area will
cause corona leak detectors to false alarm. When
searching for leaks around evaporators or other
areas where high moisture content is present,
replace the standard aluminum housing with the
patented Evaporator Filter Housing included in the
accessory pack. This filter will eliminate false alarms
caused by the presence of moisture.
• LEAK VERIFICATION:
If a suspected leak is indicated, verify several times
by moving the sensor away from the leak area,
allowing the alarm to clear and then back to the
suspected leak. If the instrument indicates a leak
three consecutive times, you have found a leak.
