6. Betjeningsvejledning

6.1 Indstilling Voltage og Nuværende

1. Vælg justeringstilstand: Tryk på Voltage/Strøm button to toggle between voltage (V) and current (A) adjustment modes. The corresponding display will show the value to be set.
2. Vælg ciffer: Brug < og > buttons to select the digit you wish to adjust. The selected digit will blink.
3. Juster værdi: Drej på Juster knap clockwise to increase the value and counter-clockwise to decrease it.
4. Aktiver output: Når den ønskede voltage and current limit are set, press the Til/Fra button to activate the output. The OUT indicator will illuminate.

6.2 Hukommelsesfunktioner (M1-M4)

• Gemmer indstillinger: Indstil den ønskede voltage and current. Press and hold one of the M1-M4 buttons for approximately 2 seconds until a beep confirms the setting is saved.
• Genkaldelse af indstillinger: Tryk kort på en af M1-M4 buttons. The stored voltage and current values will be loaded. Note that recalling a setting does not automatically activate the output; you must press the Til/Fra knap.
