• Paina AUTO/MANUAALINEN button to switch between modes. The display will indicate the currently active mode.
• In Automaattinen tila, the meter will continuously measure and update readings.
• In Manuaalinen tila, measurements are initiated by the user. The recommended test interval in Manual Mode is at least 30 seconds between measurements to ensure accurate readings and prevent overheating.

3.3. Näytön lukeminen

The large, backlit display shows the following parameters:

• Pmax: Maximum Power (in Watts)
• VMP: Voitage at Maximum Power (in Volts)
• Imp: Current at Maximum Power (in Amperes)
• voc: Open Circuit Voltage (voltteina)
• ISC: Short Circuit Current (in Amperes)

3.4. Tiedonpitotoiminto

• Paina PIDÄ button to freeze the current readings on the display. This is useful for recording stable measurements.
• Paina PIDÄ button again to release the hold and resume live measurements.

3.5. Overload and Overheat Warnings

The meter is equipped with safety features to protect the device and the user:

• Ylikuormitusvaroitus: If the input power exceeds the maximum capacity (800 W), an "Overload!" message will appear on the display. Disconnect the solar panel immediately to prevent damage.
• Ylikuumenemisvaroitus: If the internal temperature of the device becomes too high, an overheat warning will be displayed. Allow the meter to cool down before resuming operation.

4. Huolto

4.1. Puhdistus

• Ensure the meter is powered off and disconnected from all solar panels and test leads before cleaning.
• Pyyhi laitteen ulkopuoli pehmeällä, damp kangas. Älä käytä hankaavia puhdistusaineita tai liuottimia.
• Avoid getting moisture into the input terminals or any openings.

4.2. Pariston vaihto

When the battery indicator on the display shows low power, replace the 9V battery as described in the "Battery Installation" section (2.1). Always use a fresh 9V (6F22) battery.

4.3. Varastointi

• If storing the meter for an extended period, remove the battery to prevent leakage.
• Säilytä laitetta viileässä, kuivassa paikassa, poissa suorasta auringonvalosta ja äärimmäisistä lämpötiloista.
