5. Setup

5.1 Battery Installation and Charging

The HDS2202S is powered by an 18650 lithium battery, providing approximately 6 hours of continuous operation on a full charge.

1. Battery Installation: If the battery is not pre-installed, open the battery compartment cover on the rear of the device. Insert the 18650 lithium battery, ensuring correct polarity. Close the cover securely.
2. Charging: Connect the supplied USB Type-C cable to the device's USB-C port and the other end to the power adapter or a compatible power bank. The charging indicator will illuminate. A full charge typically takes several hours.

5.2 Initial Power On

Press and hold the Power button until the OWON logo appears on the screen. The device will boot into the last used mode or a default mode.

5.3 Probe Compensation (Oscilloscope)

Before taking accurate measurements with the oscilloscope, it is recommended to compensate the probes.

1. Connect an oscilloscope probe to one of the BNC input channels (CH1 or CH2).
2. Connect the probe tip to the 1kHz calibration signal output terminal and the probe ground clip to the ground terminal.
3. Press the Auto button. The device will display a square wave.
4. Adjust the compensation screw on the probe until the square wave corners are flat (neither overshot nor undershot).

6. Operating Instructions

The HDS2202S offers three primary functions: Oscilloscope, Multimeter, and Waveform Generator. Use the Mode button to switch between these functions.

6.1 Oscilloscope Function

The oscilloscope mode allows for visual analysis of electrical signals.

• Connecting Probes: Connect oscilloscope probes to CH1 or CH2 BNC inputs.
• Auto Setup: Press the Auto button for automatic scaling and positioning of the waveform.
• Manual Adjustments: Use the navigation keys and function buttons (F1-F4) to adjust vertical scale (Volts/Div), horizontal scale (Time/Div), trigger level, and position.
• Measurement: The device supports 7 types of auto measurements (frequency, period, amplitude, max, min, mean, PK-PK) and cursor measurements.
• Acquisition Modes: Supports Normal, Peak Detect, and Average acquisition modes. Peak Detect is useful for capturing glitches.
• XY Mode: For displaying Lissajous figures, useful for phase comparisons.
