7.3 Pleje af batterier
For at forlænge batteriets levetid skal enheden oplades regelmæssigt, selvom den ikke bruges hyppigt. Undgå at aflade batteriet helt i længere perioder.
8. Fejlfinding
- Enheden tændes ikke: Sørg for, at batteriet er opladet. Tilslut enheden til en strømkilde, og prøv igen.
- Ingen bølgeform vist: Check the probe connection. Ensure the input signal is within the oscilloscope's measurement range. Try using the AUTO button for automatic waveform adaptation.
- Unstable waveform: Adjust the trigger level and trigger edge settings. Ensure proper coupling (AC/DC) for your signal.
- Skærmen er svag: Adjust the brightness setting via the MENU.
- No sound/beeping: Check the mute mode setting in the MENU.
Hvis du støder på vedvarende problemer, der ikke er dækket her, bedes du kontakte kundesupport.
