4. Produk Lebihview
The diymore USB C Tester features a compact design with a 0.96-inch IPS LCD color screen for clear display of measurement data. It is housed in a durable CNC metal casing.
Rajah 4.1: diymore USB C Tester with its protective CNC metal housing and compact dimensions (31.8 x 16.1 x 8.1 mm).
The device is equipped with a USB-C input and output, allowing it to be inserted inline between a power source and a load. It features two control buttons (K- and K+) for navigating menus and adjusting settings.
5. Persediaan
The diymore USB C Tester is designed for plug-and-play operation. No external power supply is required for the tester itself.
- Connect the USB-C male connector of the tester to the USB-C output port of your power source (e.g., charger, power bank).
- Connect your USB-C device (e.g., smartphone, tablet, laptop) to the USB-C female port of the tester using a compatible USB-C cable.
- The tester's display will automatically power on and begin showing real-time measurement data.
Rajah 5.1: Example setup showing the USB C Tester connected in-line with a PD3.1 charger and a laptop.
Nota:
- 1. The tester supports peak voltage up to 36V and peak current up to 10A.
- 2. When only the PD charging head is connected without a load, the device may not start. It must be connected to a useful electrical equipment in order to work.
6. Arahan Operasi
The diymore USB C Tester features multiple display interfaces and functions, navigable via the K- and K+ buttons.
6.1. Fungsi Butang
Rajah 6.1: Quick explanation of button functions for navigating display pages and settings.
Use the K- and K+ buttons to switch between display pages, adjust settings, and confirm selections. A short press typically switches screens or values, while a long press activates specific functions.
6.2. Display Pages
The tester offers four main display interfaces:
P1: Large Display (Current/Voltage)
This page provides a clear, large character display of real-time voltage (U), current (I), and power (P). It also indicates the current direction.
- Long press K-: Switch data refresh speed (2nd gear).
- Long press K+: Rotate the screen display direction.
- Short press KEY- KEY+ button: Switch between screens forward/backwards.
Rajah 6.2: P1 interface displaying large voltage, current, and power values.
P2: Fast Charging Protocol Display & Detection
This page displays voltage (V), current (A), power (W), recording capacity (Wh), D+/D- communication line voltage, and detects fast charging protocols (PD/QC/PPS).
- Long press K-: Switch Ah, Wh capacity display unit.
- Long press K+: Switch capacity recording starting current threshold.
- Nota: Only records when current ≥ threshold; less than this current will automatically stop capacity accumulation.
Rajah 6.3: P2 interface for fast charging protocol detection and detailed charging parameters.
P3: Capacity Statistics Screen
This screen provides statistics on charging energy (Wh), recording time (R), maximum recorded values (MAX), and average values (AVG) calculated since power-on.
- Long press K-: Clear capacity records.
- Long press K+: Switch between MAX and AVG display.
Rajah 6.4: P3 interface for monitoring charging capacity statistics.
P4: Data & Cable Test Screen
This page is used for ripple testing and cable resistance measurement. It displays ripple frequency, measurement gear, ripple value, and real-time voltage, current, and power values.
- Long press K-: Enter Cable Submenu.
- Long press K+: Tukar Sampling Kekerapan.
- Nota: Measuring ripple requires a professional commercial load.

8. Penyelesaian masalah
If you encounter issues with your diymore USB C Tester, refer to the following common problems and solutions:
| Masalah | Kemungkinan Punca | Penyelesaian |
|---|---|---|
| Paparan tidak dihidupkan. | No power source or no load connected. | Ensure the tester is connected between a working power source and a device drawing power. The tester requires a load to activate. |
| Bacaan yang tidak tepat. | Faulty cable, unstable power source, or device malfunction. | Try using a different USB-C cable. Test with a known good power source and load. If issues persist, the device may require service. |
| Butang tidak bertindak balas. | Gangguan perisian sementara. | Disconnect and reconnect the tester to reset it. |
| Cannot detect fast charging protocol. | Connected device/charger does not support fast charging, or cable is not compatible. | Ensure both the charger and the device support the desired fast charging protocol (e.g., PD, QC, PPS) and that the cable is rated for it. |
