6. Kullanım Talimatları

6.1 Automatic MPPT Detection

For quick and easy measurement of the maximum power point:

1. Ensure the multimeter is connected to the solar panel as described in Section 5.
2. Basın [AUTO MPPT] test düğmesi.
3. The multimeter will automatically scan and adjust the test interval time based on the current power value. The display will refresh with the Pmax, Vmp, and Imp readings. For example, for a 100W solar panel, the display refreshes every 5 seconds; for a 350W panel, every 15 seconds; and for a 700W panel, every 30 seconds.

6.2 Manual MPPT Detection

For a more controlled measurement of the maximum power point:

1. Ensure the multimeter is connected to the solar panel.
2. Basın [MANUAL MPPT] test düğmesi.
3. The instrument will initiate a scan for the maximum power point. The display will show the Pmax, Vmp, and Imp readings. The test interval time adjusts automatically based on the power value; higher power may result in a longer interval. The last test results will be retained on the display.

6.3 Açık Devre Cilttage (Voc) Detection

When the multimeter is operating, the LCD will continuously display the open-circuit voltage (Voc) of the solar panel in real-time.

6.4 Arka Işık Kontrolü

Basın [BACKLIGHT] button to toggle the LCD backlight on or off for improved visibility in different environments.

8. Kullanıcı İpuçları

• Understanding Power Readings: The multimeter measures the maximum power point (Pmax) of your solar panel under current conditions. This reading might differ from the panel's rated power, which is typically measured under Standard Test Conditions (STC). Factors like sunlight intensity, temperature, and panel degradation can affect the actual Pmax.
• Kullanım Amacı: This device is specifically designed for testing solar (photovoltaic) panels to determine their MPPT and open-circuit voltage. It is not suitable for measuring the power output of batteries or other electrical sources.
• Optimal Testing Conditions: For the most accurate results, test your solar panels on a clear, sunny day with minimal cloud cover.

9. Bakım

To ensure the longevity and accuracy of your solar panel multimeter:

• Temizlik: Cihazı yumuşak ve kuru bir bezle silin. Aşındırıcı temizleyiciler veya çözücüler kullanmayın.
• Depolamak: Store the multimeter in its EVA tool bag in a cool, dry place away from direct sunlight and extreme temperatures when not in use.
• Denetleme: Periodically check the connecting cables and alligator clips for any signs of wear or damage. Replace them if necessary.
