4. Configuració
4.1. Carregant la bateria
The ALD-200 PRO HP is powered by a built-in 3000mAh rechargeable Lithium-Ion battery. Before first use, fully charge the device.
- Connect the provided USB-C charging cable to the USB port on the device.
- Connecteu l'altre extrem del cable USB-C a un adaptador de corrent USB compatible (no inclòs).
- The battery indicator on the display will show charging status. A full charge typically takes approximately 4 hours with a standard 2.1W charging block, or less with a 5W block.
- Desconnecta el carregador un cop la bateria estigui plena.

4.2. Encès / apagat
Premeu i manteniu premut el botó d'engegada (normalment marcat amb un símbol d'engegada) per encendre o apagar el dispositiu.
4.3. Escalfament
After powering on, the device will undergo a warm-up period, typically lasting about 30 seconds. During this time, the display may show a "WARM UP" indicator. Wait for the warm-up to complete before beginning leak detection.
5. Funcionament
Follow these steps for effective refrigerant leak detection:

5.1. Ajust de sensibilitat
The device has three sensitivity levels: High, Medium, and Low. The default sensitivity level is typically the lowest (L). Press the SENS button to cycle through the sensitivity modes. Higher sensitivity is suitable for detecting very small leaks, while lower sensitivity helps to narrow down the leak source in areas with higher background refrigerant levels.
5.2. Leak Detection Procedure
- Turn on the detector and allow it to complete its warm-up cycle (approximately 30 seconds).
- Ensure the area is free of known refrigerant concentrations before starting. If necessary, move to a fresh air environment and press the GAS/RSET button to reset the baseline.
- Slowly move the sensor probe at a distance of approximately 0.25 inches (6mm) per second near the suspected leak area.
- Observe the display and listen for audible alarms. The alarm frequency and visual bar graph will increase as the probe approaches a leak source.
- Once a leak is detected, move the probe away briefly and then return to confirm the location.

5.3. Understanding Alarms (Audible & Visual)
When a leak is detected, the device provides both audible and visual feedback:
- Alarma sonora: A buzzer will sound, increasing in frequency as the concentration of refrigerant gas rises.
- Visualització visual: The color graphic display features a bar graph that indicates the leakage level. The bars will illuminate and change color (e.g., from green to yellow to red) as the leak concentration increases, helping to visually pinpoint the source.

Image 5.3: The device provides clear audible and visual alarms, with a bar graph indicating the intensity of the detected leak.
5.4. Peak Function
Premeu el botó PIC button to activate the peak function. This feature records and displays the maximum leakage value detected during continuous operation. This is useful for identifying the most significant leak point in complex environments.

5.5. Automatic Reset (GAS/RSET)
El GAS/RSET button allows you to automatically reset the sensitivity benchmark. Press and hold this button for 3 seconds to reset the device's baseline. This is particularly useful when moving from an area with a high concentration of refrigerant to a cleaner area, ensuring accurate detection of new leaks.
5.6. Funció de silenci
Premeu el botó MUT button to turn the audible buzzer on or off. This allows for discreet operation in noise-sensitive environments while still relying on the visual display for leak indications.
6. Manteniment
6.1. Sensor Probe Care
The 16-inch flexible sensor probe is a critical component. Handle it with care to prevent damage. Avoid bending it sharply or exposing it to excessive force. Keep the probe tip clean and free from debris.
