Operating Instructions

5.1 Main Interface

The main interface displays key measurement information. Key elements are:

• 1. Measurement Range: Indicates the current selected measurement range (e.g., DC Current).
• 2. Measurement Parameter: Displays the measured value (e.g., 600 A).
• 3. Unit: Shows the unit of measurement (e.g., A for Amperes).
• 4. Minimum Value: Displays the minimum value recorded during the measurement session.
• 5. Maximum Value: Displays the maximum value recorded during the measurement session.
• 6. Range Switching: Short press the [HOLD] and [V-A] buttons to switch between measurement ranges (DC Current, DC Voltage, Resistance, Capacitance, Frequency, and Live/Neutral Line Detection). Short press the [MODE] button to switch between other test functions within the current range (e.g., DC Current/AC Current).
• 7. Data Hold: Long press the [HOLD] button to hold the current test data. When data is held, "HOLD" will be displayed.
• 8. Flashlight: Long press the flashlight button to turn the flashlight on or off. When the flashlight is on, a flashlight icon will be displayed; when it is off, it will not be shown.
• 9. Data Reset: For DC Current measurements only, short press the power button to reset the data. A 'Z' symbol will be displayed when the data is reset.
• 10. Battery Level: When the battery is full, a full battery icon [battery-full] will be displayed. When the battery is low, a low battery icon [battery-low] will be shown. If the battery level becomes critically low, a popup alert will appear, and the device will automatically start a countdown to shut down.

5.2 Waveform Display Interface

Long press the [MODE] button to enter the waveform display interface.

• 1. Measurement Parameter: Displays the current measurement value.
• 2. Unit: Shows the unit of measurement.
• 3. Measurement Range: Indicates the current measurement range.
• 4. Waveform Display: Shows the waveform of measurement data changes.
• 5. Data Saving: Short press the [SAVE/MENU] button to save data. This section can store up to 8 sets of data. For more data, check the historical records in the settings interface.
• 6. Minimum Value: Displays the minimum recorded value.
• 7. Maximum Value: Displays the maximum recorded value.

5.3 Power Measurement Interface

Long press the [V-A] button to enter the power measurement interface. In this mode, AC and DC are automatically recognized.

• 1. Current Data: Displays the measured current.
• 2. Power Calculation: Shows the calculated power (in Watts).
• 3. Voltage Data: Displays the measured voltage.

5.4 Settings Interface

Long press the [SAVE/MENU] button to enter the settings interface.

• 1. Settings Options: Navigate through History Records, System Settings, Factory Reset, and About.
• 2. Specific Settings:
  • [History Records]: Short press [SAVE/MENU] to save data during measurements. Up to 30 sets of data can be saved in history records.
  • [System Settings]:
    • Language: Select between Simplified Chinese / English.
    • Brightness: Adjust brightness across 10 levels.
    • Temperature Unit: Select between °C / °F.
    • Auto Power Off: Configure auto power off for OFF, 5 min, 15 min, or 30 min.
  • [Factory Reset]: Restore factory settings.
  • [About]: View brand information and version number.

Firmware Upgrade

To upgrade the firmware:

1. With the device powered off, press and hold the [HOLD] and [SAVE/MENU] buttons, then press the [Power] button to turn it on. The screen will display “Firmware Upgrade.”
2. Connect the device to a computer using a data cable. The computer will detect a "BOOT" disk.
3. Copy the "firmware" file or startup image to the detected disk.
4. Press the [SAVE/MENU] button to start the upgrade process.

Precautions

• Before using the product, check if the insulation near the casing and interfaces is damaged.
• Hold the probes by the protective grips.
• Do not touch any of the input ports when measuring a circuit.
• Disconnect the test probes from the circuit before changing the measurement range.
• When measuring DC voltages above 36V or AC voltages above 25V, exercise caution to avoid electric shock.
• Select the correct range for measurement to avoid damaging the instrument. The screen will display "OL" when the measurement exceeds the range.
• When the battery level is critically low, a popup will alert you. Charge the battery promptly to avoid affecting measurement performance. Do not use the device while it is charging.
