4. OPERATING FEATURES:
This unit includes operating features designed to increase usability and simplify user Interface.
Please refer to Fig 1 to familiarize yourself with the indicators and keypad controls as you proceed through this
section.
4.1
Battery Voltage Indicator
:
The Battery Voltage Indicator allows the user to see the battery level at all times.
The first LED from the bottom is an “intelligent” battery status indicator and remains on whenever the unit is
powered on and completes the warm-up. The LED will illuminate in one of three colours to indicate the battery
voltage level:
If the LED is blue, the batteries are fully charged
If the LED is purple, the batteries have enough voltage to operate
If the LED is red, the batteries should be immediately recharged to prevent erratic performance or failure of
detection.
4.2 Automatic Circuit/Reset feature:
The unit features Automatic Circuit and Reset functions that set the unit to ignore ambient concentrations of
refrigerant.
Automatic circuit - Upon initial power-on and completion of the warm-up, the unit automatically sets itself to ignore
the level of refrigerant present at the tip. Only a level, or concentration, greater than this level will cause an alarm.
Note: Since this feature causes the unit to ignore any refrigerant present at the sensor tip after warm-up is
completed, the unit should be powered on and allowed to warm up in fresh air.
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. Each time the Reset key is pressed (and released), the unit sets its threshold
for detection to a level above the current concentration being detected. By moving closer to a large leak, and
pressing Reset each time a full detection is indicated, the user can pinpoint the source of the leakage. 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. If need to reset
the unit, press the Reset key. Each time the Reset key is pressed, all LEDs briefly show purple for about three
seconds to provide a visual confirmation of the reset action.
4.3 Sensitivity Adjustment
The unit provides seven levels of sensitivity adjustment. When the unit is switched on, it is set to the lowest
sensitivity position.
To change the sensitivity of the unit, press the Sensitivity key, and the LEDs light in blue. The number of lighted LED
will indicate the level of sensitivity. For example, if five LED light, it represents that the sensitivity of detector has
been adjusted to the fifth level. Seven level sensitivity could be real-time adjusted in circulation.
The standard beeping tone is also an indication of sensitivity level:
- In HIGH sensitivity, the unit emits high frequency BEEPING, and in LOW sensitivity the unit emits low frequency
BEEPING.
