5. Onderhoud

Proper maintenance ensures the longevity and accuracy of your FNIRSI 2C53T.

• Skoonmaak: Use a soft, dry cloth to clean the device. Do not use abrasive cleaners or solvents. Ensure no liquids enter the device.
• Batterysorg: Om die batterylewe te verleng, vermy om die toestel gereeld heeltemal te ontlaai. As dit vir lang tydperke gestoor word, laai die battery tot ongeveer 50% en herlaai dit elke paar maande.
• Berging: Store the device in a cool, dry place away from direct sunlight, extreme temperatures, and high humidity. Use the provided storage bag to protect it from dust and physical damage.
• Sondeversorging: Inspect probes and cables regularly for any signs of wear or damage. Replace damaged components immediately to ensure safety and accurate measurements.

6. Probleemoplossing

If you encounter issues with your FNIRSI 2C53T, refer to the following common troubleshooting steps:

• Toestel skakel nie aan nie: Ensure the battery is sufficiently charged. Connect the device to a power source using the Type-C cable and try again.
• Verkeerde lesings: Verify that probes are correctly connected and not damaged. Ensure the correct measurement mode is selected for the task. Check probe compensation for oscilloscope measurements.
• Onstabiele golfvorm: Adjust the trigger settings (level, mode) in oscilloscope mode. Ensure the input signal is within the device's specifications.
• Functions Not Working Simultaneously: Remember that the oscilloscope, multimeter, and signal generator functions cannot be used at the same time. Switch between modes as needed.
• Probleme met rekenaarverbinding: Ensure the Type-C cable is properly connected. Check your computer's device manager to see if the device is recognized.
