AUTOMATIC CIRCUIT/RESET FEATURE
This item features an Automatic circuit and a Reset function key that set the unit to ignore ambient
concentrations of refrigerant.
Automatic circuit: Upon initial power on, the unit automatically set itself to ignore the level of
refrigerant present at the tip. Only a level, or concentration, greater than this will cause an alarm.
Reset Feature: Pressing the RESET key during operation performs a similar function. When the
RESET key is pressed, it programs the circuit to ignore the level of refrigerant present at the tip.
The unit can be moved to fresh air and reset for maximum sensitivity. Resetting the unit with no
refrigerant present (fresh air) causes any level above zero to be detected.
Whenever the unit is reset, the LED (except the leftmost power indicator) will all turn off.
NOTE
Make a leakage test after any repair or service of climate systems.
SENSITIVITY ADJUSTMENT
The unit features sensitivity adjustment and can be adjusted during the course of detecting.
Press the button (
▲
Sensitivity) causes an increase of sensitivity.
Press the button (
▼
Sensitivity) causes an decreases of sensitivity. It does not mean, when to select,
the higher the flexibility is adjusted, the better the unit will work, because if the air is not fresh,
selecting higher flexibility will cause an improper alarm.
LEAK ALARM
When the leaked gas is detected, the buzzer will respond loudly according to the leaked quantity and
the number of the leak indicators will change as well.
OPERATING INSTRUCTIONS
Switch the unit on by pressing the ON/OFF key. The leftmost indicator will light with intermittent
humming noise.
Verify the battery level by observing the constant power indicator.
Select appropriate sensitivity and the unit can be adjusted at any time, which does not intemupt
detection.
Press RESET key to detect 6 seconds later after the unit is switched on.
Please reset the unit far away from the leak source so as to ensure the unit to detect accurately
with firm reliability.
OPERATING TIPS
Adjust the sensitivity up, only when a leak can't be found. Adjust the sensitivity down only when
resetting the unit does not allow you to "home in" on the leak.
When the buzzer alarms for leak, if the probe is remained at the part being detected long enough,
the circuit will equalize it.
In areas that are heavily contaminated with gas, the unit may be reset to block out ambient
concentrations of gas.
In windy areas, even a large leak can be difficult to find. Under these conditions, it its best to
shield the potential leak area.
Be aware that the detector may alarm if the sensing tip comes in contact with moisture and/or
solvents, therefore, avoid contact with these when leak checking.
