REFRIGERANT LEAK DETECTOR SEGO DTCTR
3. Battery installation
3.1 Installing batteries:
Open the battery cover, then install the batteries to the battery compartment of leak detector. Please pay
attention to the direction during installation. (see Fig 2)
4.Functions and Feat
The product is easy to operate and simplifies 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. If the indicator is off, the
batteries are in full power;
If the indicator is on, the batteries have enough voltage for operation;
If the indicator is fast flashing, low batteries, need to change batteries at the soonest to prevent unstable
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, LED
displays "8" about three seconds to provide a visual confirmation of the reset action.
4.3 Sensitivity Adjustment
The unit provides six 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, LED screen will display the corresponding sensitivity
level. Six level sensitivity could be real-time adjusted in circulation.
4.4 Sensor Status Indicator
The product has the ability to automatically diagnose and indicate the sensor's Status. Whenever the product is
turned on, the circuit automatically senses the condition of the sensor and can detect a failed or missing sensor.
Failed Sensor Indication:
