3. Setup

1. Unpacking: Carefully remove the ET827 device and all accessories from its packaging. Inspect for any signs of damage.
2. Power Source: The device is battery-powered. Ensure appropriate batteries are inserted into the battery compartment, observing correct polarity. (Note: Batteries are not included with the product).
3. Initial Power On: Turn the multi-function dial from the "OFF" position to any desired measurement mode (e.g., V~ for AC Voltage) to power on the device.
4. Self-Test: The device will perform a brief self-test upon power-on. Wait for the display to stabilize before proceeding with measurements.

4. Operating Instructions

4.1 General Operation

The ET827 features a multi-function dial for selecting measurement modes and dedicated function buttons (F1-F4) for specific operations within each mode. The display provides clear readings and waveform visualizations.

4.2 Oscilloscope Function

To use the oscilloscope function, turn the dial to the "OSC" position. The device will display a waveform. The ET827 supports a 40MHz analog bandwidth and 200Msps sampling rate for accurate waveform capture.

• Automatic Waveform Capture: In waveform mode, press the "R" button (often labeled F1 or a dedicated button) to automatically capture and optimize the waveform display.
• Adjustments: Use the function buttons to adjust parameters such as time base (12.5ns/div ~ 10s/div), vertical amplitude (500mV/div ~ 200V/div), trigger level, and gradient.
• Cursor Measurement: Utilize the cursor function to measure dV (voltage difference), dt (time difference), and 1/dt (frequency).
• Automatic Measurement: The device can automatically measure Vp-p (peak-to-peak voltage), Vavg (average voltage), and Vrms (root mean square voltage).

4.3 Multimeter Function

Rotate the multi-function dial to the desired measurement parameter (e.g., V for voltage, A for current, Ω for resistance, C for capacitance, Hz for frequency, °C for temperature, Diode, hFE for triode, Continuity). Connect the test leads to the appropriate input jacks (VΩCx mA°C, 10A, COM).

• TRMS Measurement: The device supports True RMS measurement, providing accurate readings for non-sinusoidal waveforms.
• REL Function: The REL (Relative) function helps eliminate the influence of lead resistance and distributed capacitance for more precise measurements.
• Auto/Manual Ranging: The device supports both automatic and manual ranging for various measurements.

4.4 Scanning Modes

The oscilloscope function offers three scanning modes:

• Auto Mode: Automatically adjusts the time base and vertical amplitude for a stable waveform display.
• Normal Mode: Displays a waveform only when a trigger condition is met. Useful for capturing specific events.
• Single Mode: Captures and displays a single waveform when the trigger condition is met, then stops. Ideal for non-repetitive signals.

4.5 Data and Waveform Storage

The ET827 allows users to save measurement data and captured waveforms for later analysis.

• Saving Data: The device can store up to 100 sets of measurement data. Refer to the specific button (e.g., 'S' or F4) for saving data in multimeter mode.
• Saving Waveforms: Up to 50 waveforms can be saved in oscilloscope mode. Use the designated save function button.
• Recalling Data/Waveforms: Navigate through the saved data and waveforms using the appropriate menu options or buttons (e.g., 'R' or F1 for recall).

5. Maintenance

• Cleaning: Use a soft, damp cloth to clean the device's exterior. Do not use abrasive cleaners or solvents.
• Storage: When not in use for extended periods, store the device in a cool, dry place, away from direct sunlight and extreme temperatures.
• Battery Care: If the device will not be used for a long time, remove the batteries to prevent leakage and damage.
• Fuse Replacement: The device has built-in 500mA/10A fuses for protection. If a fuse blows, replace it with a fuse of the same type and rating. Refer to the device's internal diagram for fuse location if necessary.
