2. Packing List

Please verify the contents of your package upon receipt:

• 1 x ET828PRO 2-in-1 Oscilloscope Multimeter Unit
• 1 x Pair of Test Leads (Red and Black)
• 1 x Cloth Carrying Bag
• 1 x Instruction Manual (this document)

3. Setup

The ET828PRO is designed for immediate use. Follow these steps for initial setup:

1. Power On: Press and hold the power button (usually integrated with the rotary switch) to turn on the device. The 2.4-inch color display will illuminate.
2. Connect Test Leads: Insert the red test lead into the 'VΩCx' input jack and the black test lead into the 'COM' input jack for most voltage, resistance, and capacitance measurements. For current measurements, use the 'mA' or '10A' input jacks as appropriate. Ensure connections are secure.
3. Initial Check: The device will typically power on in multimeter mode. You can switch between modes as described in the Operating Instructions section.

4. Operating Instructions

4.1. Oscilloscope Function

The oscilloscope mode allows for the visualization and analysis of electrical waveforms. The ET828PRO features a 50 Msps sampling rate and 10 MHz analog bandwidth for accurate waveform capture.

• Entering Oscilloscope Mode: From the multimeter interface, long press the 'R' key to switch to oscilloscope mode.
• Automatic Waveform Capture: The device includes a one-touch automatic waveform capture function, simplifying the process of acquiring stable waveforms.
• Waveform Scanning Modes: Three scanning modes are available:
  • Automatic Mode: Automatically adjusts settings to display a stable waveform.
  • Normal Mode: Captures a waveform when a trigger signal is detected.
  • Single Mode: Captures a single waveform when a trigger signal is detected and then stops.
• Parameter Adjustment: Waveform parameters such as time base and amplitude can be set independently using the function keys (F1-F4) and rotary switch.

4.2. Multimeter Function

The multimeter function provides precise measurements of various electrical parameters. It supports both automatic and manual range switching.

• Measurement Types: The ET828PRO can measure:
  • AC and DC Voltage
  • AC and DC Current (mA, 10A ranges)
  • Resistance
  • Capacitance
  • Frequency
  • Duty Cycle
  • Diode Detection
  • Continuity (On/Off Test)
• Data Display: Real-time measurement data and stored data can be displayed simultaneously on the screen.
• Data Hold: Use the data hold function to freeze the current reading on the display for easier recording.

5. Maintenance

Proper maintenance ensures the longevity and accuracy of your ET828PRO device.

• Cleaning: Use a soft, dry cloth to clean the device. Do not use abrasive cleaners or solvents. Ensure the device is powered off before cleaning.
• Storage: Store the device in a cool, dry place, away from direct sunlight and extreme temperatures. Use the provided cloth bag for protection when not in use.
• Fuse Replacement: The ET828PRO is equipped with a 10A double fuse for protection. If the device fails to measure current or shows incorrect readings in current mode, the fuse may need replacement. Refer to a qualified technician for fuse replacement to ensure proper safety and functionality.

6. Troubleshooting

If you encounter issues with your ET828PRO, refer to the following common troubleshooting steps:

• Device Not Powering On: Ensure the rotary switch is in an 'ON' position. If the device has a rechargeable battery, ensure it is sufficiently charged.
• No Reading or Incorrect Reading:
  • Check that the test leads are securely connected to the correct input jacks for the desired measurement.
  • Verify that the rotary switch is set to the appropriate measurement function.
  • For current measurements, check if the fuse needs replacement (see Maintenance section).
  • Ensure the circuit being tested is within the device's specified measurement range.
• Display Issues: If the display is dim or flickering, the battery may be low. Recharge the device if applicable.
• Overload Protection: The device has built-in overload protection. If an overload occurs, the device may temporarily stop functioning or display an error. Remove the overload condition and restart the device.
