Description of Product Functions
On/Off
On/Off: Long press the power button ” ” for 2s to turn off.
Power on preheating: After powering on, the instrument will automatically
preheat. A 30-second countdown will begin, and upon countdown completion,
twill enter the reading mode, allowing for testing to commence.
When the instrument s turned on, it will automatically perform a sensor self-
check (a beep from the buzzer +motor vibration). If the self-check is normal,
the preheating countdown will commence.
If a sensor malfunction occurs, the screen will display “Sensor Malfunction”, requiring the instrument to be returned to the factory for repairs.
Gas Detection
Detectable Gases:
Detection of halogen gases (including chorine and fluorine); Detection of the
medical ethylene oxide, ethanol gas, etc. Detection of the halon gas in fire
extinguishing systems; Detection of the air conditioner, refrigeration
systems, refrigerant recovery units, etc.
- CFCS (Chlorofluorocarbons): R11, R12, R13, R113, R114,R502, R500, R503, R170, R600a, R1270, etc.
- HCFC (Hydrochlorofluorocarbons) R22, R32, R123, R124,R141b, R142b, R402A, R402B, R403A, R409A, etc
- HFCS (Hydrofluorocarbons): R410a, R134a, R404a, R125, R407C, R417A, R507, R23, R1343, etc.
Overrun Alarm:
Gas concentration value < Low-limit alarm, displayed in white font, no
alarm.
Low-limit alarm < Gas concentration value < High- limit alarm, displayed in
white font, intermittent vibration, soft beeping.
Gas concentration value > High-limit alarm, displayed in red font, continuous
vibration, rapid beeping.
Operation Skills:
- In open areas with good ventilation, it may be difficult todetect even largerleaks because the leaked refrigerant dissipates quickly. In such cases, it is recommended to cover the areas where leaks may occur.
- Whenthereare multiple leakage points, itis recommended to firstidentify the more severe ones. Once the major leakage points are located, it will be easier to find the minor ones.
- If the probe comes into contact with methane or other volatile gases, it may trigger an alarm. Therefore, this situation should be avoided during inspection.
Notes:
- During detection, the air conditioner or refrigeration equipment should be filled with sufficient refrigerant.
- Please keep the probe clean to avoid affecting the detection results.
- 1n a refrigeration system, detection should be carried out along a continuous path. When conducting leak detection, the probe should be moved around the component being inspected at a rate not exceeding 25-50mm/s and kept at a distance from the surface not exceeding 5mm. It is essential to fully encircle the component during movement to achieve optimal results. An alarm indicates that a leak has been found
- Please do not exposethe instrument to high concentrations of corrosive gases (such as alcohol, smoke, formaldehyde, toluene, benzene, acetone, lighter gas and paint), as it may cause corrosion or damage to heating materials and sensor wires, and lead to irreversible degradation of the sensitive material’s performance.
Temperature Monitoring
This product utilizes temperature measurement using a thermistor (°C/°F).
When testing the ambient temperature, the instrument needs to be placed in the
environment for at least half an hour.
Setting
After powering on, short press Setting ” “to enter the setting interface.
In the setting interface, press Up/Down ” “to switch between language setting,
alarm setting, unit setting, auto power-off setting, and information about
this instrument.
- Language setting: Switch between simplified Chinese and English.
- Alarm setting: The high-limit alarm value and the low-limit alarm value can be set (Note: The high- limit alarm value must be greater than the low- limit alarm value).
- Unit setting: The refrigerant gas unitis defaulted to be in PPM. : Switch the temperature unit (°C/°F);
- Auto power-off setting: The auto power-offtime can be set (15min, 30min, 60min, never). When the autopower-off time is set, an auto power-off icon” ” willbe displayed in the top left corner of the main interface.
