2.4 Selvtjekfunktion
The device includes a self-check feature. By opening the back cover and inserting the included 1.5V AAA battery, the battery's remaining capacity is displayed in the upper right corner of the LCD screen, allowing for quick assessment of the internal battery's charge. This ensures simple, convenient, and durable operation.
3. Pakkens indhold
- Dlyfull B3 Battery Checker x1
- 1.5V AAA Batteries x2 (pre-installed)
- Brugsanvisning x1
4. Opsætning
Before first use, ensure the internal 1.5V AAA batteries are properly installed. These batteries power the tester's LCD display and internal circuitry.
- Locate the battery compartment on the back of the Dlyfull B3.
- Åbn batterirummets dæksel.
- Verify that the two 1.5V AAA batteries are correctly inserted with the correct polarity (+/-).
- Luk batterirummets dæksel forsvarligt.
5. Betjening
Follow these steps to accurately test your batteries:
- Vælg batteritype: Rotate the central dial on the Dlyfull B3 to match the voltage and type of the battery you intend to test. Ensure the selected setting corresponds accurately to your battery (e.g., 1.5V ALK for alkaline batteries, 3.7V Li-ion for lithium-ion batteries).
- Tilslut testprober:
- Tilslut rød test probe to the positive (+) terminal of the battery.
- Tilslut sort test probe to the negative (-) terminal of the battery.
- Læs mål: Hold the probes in place for approximately 2 seconds. The LCD screen will display the following information:
- Voltage (V): Den nuværende voltage af batteriet.
- Internal Resistance (Ω): The internal resistance value of the battery.
- Remaining Capacity (%): An estimated percentage of the battery's remaining charge.
- Fortolk resultater: Use the displayed information to assess the battery's health. A low voltage, high internal resistance, or low remaining capacity may indicate that the battery needs to be recharged or replaced.

6. Vedligeholdelse
- Rensning: Tør enheden af med en blød, tør klud. Brug ikke slibende rengøringsmidler eller opløsningsmidler.
- Opbevaring: Store the Dlyfull B3 in a cool, dry place away from direct sunlight and extreme temperatures.
- Udskiftning af batteri: If the internal 1.5V AAA batteries that power the tester's display are low, replace them promptly to ensure accurate readings and proper device function.
- Probepleje: Keep the test probes clean and free of debris to ensure good electrical contact. If terminals are dirty, clean them before testing.
7. Fejlfinding
- Intet display/svagt display:
- Check if the internal 1.5V AAA batteries are installed correctly and have sufficient charge. Replace if necessary.
- Upræcise læsninger:
- Ensure the rotary dial is set to the correct battery type and voltage.
- Verify that the test probes have firm and clean contact with the battery terminals. Clean terminals if dirty.
- Test the device with a known good battery to confirm functionality.
- Enheden reagerer ikke:
- Remove and reinsert the internal AAA batteries.
- Kontakt kundesupport, hvis problemet fortsætter.
