Automatic Circuit/Reset Function:
Automatic Circuit: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 refrigeran 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.
Reset Feature:Pressing the RESET key during operation performs a similar unction. When the RESET key is pressed it programs the circuit to gnore the level of refrigerant present at the tip. This allows the user tc 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 leve above zero to be detected.Whenever the unit is reset, the LEDs (except the leftmost power indicator) will turn Red for 1 second. This provides al visual confirmation of the reset action.
