AUTOMATIC AMBIENT RESET FEATURE:
The Refrigerant leak detector features an Automatic Ambient Reset function
that sets the unit to ignore ambient concentrations of refrigerant.
• Automatic Ambient Setup - Upon initial power on, the unit automatically
sets itself to ignore the level of refrigerant present at the tip. Only a
level, or concentration greater than this will cause an alarm.
CAUTION!
Be aware that this feature will cause the unit to ignore any refrigerant
present at turn on. In other words, with the unit off if you place the tip up to a
known leak and switch the unit on, no leak will be indicated!
• Ambient Reset Feature - Resetting the unit during operation performs a
similar function, it programs the circuit to ignore the level of refrigerant
present at the tip. This allows the user to "home-in" on the source of the
leak (higher concentration). Similarly, 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.
• After the unit is warmed up, the default sensitivity level is set at "High"
and Auto Reset function is "ON".
• Auto Reset function is best used initially when user is moving around
trying to identify leakage source. Once the leak source is determined,
cancel the Auto Detect function to proceed with leakage measurement.
• Auto Reset function should be turned OFF when use in fixed position
leakage detection.
FEATURE SENSITIVITY ADJUSTMENT:
The instrument provides two levels of sensitivity. When the unit is switched
on, it is set to the high sensitivity level.
• To change the sensitivity, press the "Lo" key. When this key is pressed,
the visual display will momentarily show the two left LED's (green)
indicating low sensitivity level is selected.
• To switch back to high sensitivity, press the "Hi" key. The two right LED's
(red) will light momentarily indicating high sensitivity level is selected.
