4. התקנה
4.1 מה בקופסה
- diymore U-18 USB Tester Meter
4.2 חיבור ראשוני
To begin using the U-18 USB Tester Meter, connect it inline between your power source (charger, power bank) and the device you wish to test.
- Connect the USB-A Input (4V-24V) or Type-C Input port of the U-18 to your power source.
- Connect the USB-A Out (0-6.5A) or Type-C Output port of the U-18 to your device (e.g., smartphone, tablet, laptop).
- התצוגה תידלק אוטומטית ותתחיל להציג נתוני מדידה בזמן אמת.
5. הוראות הפעלה
5.1 Basic Measurement Display
Upon connection, the tester will display key parameters on its 1.77-inch TFT screen.
Figure 5.1: The tester's display showing voltage, current, power, energy, capacity, and fast charging protocol information.
- כרך ידtagתצוגה אלקטרונית: מציג את כרך בזמן אמתtagה (V).
- תצוגה נוכחית: Shows the real-time current (A).
- תצוגת כוח: Shows the real-time power (W).
- סטטיסטיקות אנרגיה: Accumulates total energy consumed (Wh).
- Capacity Statistics: Accumulates total charge capacity (Ah).
- Fast Charging Protocol Display: Indicates detected fast charging protocols (e.g., PD, QC2.0, QC3.0).
5.2 Navigating Display Interfaces
The U-18 offers 7 types of display interfaces. Use the KEY - ו מקש + buttons (labeled 2 and 3 in Figure 3.2) to cycle through different display modes and settings.

5.3 Cable Internal Resistance Measurement
This feature allows you to assess the quality of your USB cables.
Figure 5.3: The tester connected to a power source and device, displaying cable resistance measurement.
- Connect the U-18 to a power source.
- Navigate to the "Cable Measurement" interface (refer to Figure 5.2).
- Connect the cable you wish to test between the U-18's output and a load (e.g., a device drawing current).
- The system will automatically calculate and display the cable's internal resistance. A lower resistance indicates a better quality cable.
5.4 כיוון התצוגה
To toggle the display orientation, long-press the מקש + button (labeled 3 in Figure 3.2).
6. תחזוקה
- Keep the device clean and dry. Use a soft, dry cloth to wipe the screen and casing.
- הימנע משימוש בחומרי ניקוי שוחקים או ממסים.
- אחסן את המכשיר במקום קריר ויבש כאשר אינו בשימוש.
7. פתרון תקלות
- אין תצוגה: Ensure the tester is properly connected to a power source and a load. Check if the power source is active.
- קריאות לא מדויקות: Verify that all connections are secure. Ensure the power source and load are functioning correctly. Readings can be affected by poor quality cables or unstable power sources.
- מכשיר לא נטען: Check the connections between the tester, power source, and device. Ensure the power source is providing sufficient power.
- Cable Resistance Reads 9999.9Ω: This typically indicates an open circuit or a very poor connection in the cable being tested. Re-check cable connections.
