3.3. Aflæsning af displayet

The large, backlit display shows the following parameters:

• Pmax: Maximum Power (in Watts)
• Vmp: Voltage at Maximum Power (in Volts)
• Imp: Current at Maximum Power (in Amperes)
• Voc: Open Circuit Voltage (i volt)
• Ise: Short Circuit Current (in Amperes)

3.4. Datahold-funktion

• Tryk på HOLDE button to freeze the current readings on the display. This is useful for recording stable measurements.
• Tryk på HOLDE 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:

• Advarsel om overbelastning: 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.
• Advarsel om overophedning: 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. Vedligeholdelse

4.1. Rensning

• Ensure the meter is powered off and disconnected from all solar panels and test leads before cleaning.
• Tør ydersiden af ​​enheden af ​​med en blød, damp klæde. Brug ikke slibende rengøringsmidler eller opløsningsmidler.
• Avoid getting moisture into the input terminals or any openings.

4.2. Udskiftning af batteri

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. Opbevaring

• If storing the meter for an extended period, remove the battery to prevent leakage.
• Opbevar enheden et køligt, tørt sted, væk fra direkte sollys og ekstreme temperaturer.
