5. Operating Instructions

The tester's display will automatically activate upon connection, showing real-time measurements.

5.1 Understanding the Display

The LCD screen displays various parameters simultaneously, including voltage (V), current (A), power (W), accumulated capacity (mWh), timing (T), and more.

Description: Examples of the tester's display, showing functional interface readings for voltage, power, current, time, and capacity. It also illustrates warning pages that appear when measured voltage or current exceeds or falls below set thresholds, such as 'Greater than setting voltage warning page' (50.0V) and 'Less than setting current warning page' (000.A).

5.2 Multifunction Button Operations

• Short Press: Briefly press the multifunction button to cycle through different display interfaces or to turn the screen on/off.
• Triple Press (Quickly): Press the button three times quickly to reset the accumulated power (mWh) and timing data for the current group to zero.
• Long Press (2 seconds): Press and hold the button for 2 seconds to switch between accumulated data storage groups (NO.X). This allows you to store and view different sets of measurement data.

6. Applications

This tester is ideal for evaluating the performance of various Type-C compatible devices and accessories.
