After receiving your oscilloscope, please perform the following checks:

Check the shipping package: Inspect for any damage caused by transportation. If the packaging cartons or protective foam are seriously damaged, keep them until the entire machine and accessories have passed electrical and mechanical testing.

Check the accessories: Refer to Appendix A in the user manual to ensure all accessories are present and undamaged. If anything is missing or damaged, contact your dealer.

Check the machine: If you find that the instrument is damaged, not working properly, or fails its performance test, contact the dealer responsible for the sale.

Follow these steps to prepare your oscilloscope:

1. Adjust the Supporting Legs: The HANTEK HRDO4254D has a bracket at the bottom. Adjust it to tilt the oscilloscope slightly upwards for better placement stability and easier viewing.

2. Connect to AC Power: Use the provided power cord to connect the oscilloscope to a power supply. The required input is 47-440Hz, 90-264VAC/127-320VDC, 80Watts MAX. Ensure the instrument is correctly grounded to avoid electric shock.

3. Turn-on Checkout: Press the power button on the lower left of the front panel. During startup, all button lights will illuminate briefly, and the oscilloscope will perform self-checks. The startup screen will appear upon completion.

To ensure your oscilloscope is functioning correctly, follow these steps:

1. Click [Default Setup] in the button area to restore the oscilloscope to factory settings.

2. Connect the grounding crocodile clamp wire of the probe to the grounding terminal on the front panel.

3. Connect the probe tip to the input terminal of channel 1 AND the compensation signal output terminal (marked with a square wave symbol).

4. Set the probe attenuation ratio to X10 and click the [Auto Scale] button.

5. Observe the waveform on the screen. A stable square wave should be displayed. If not, you may need to perform probe compensation.

6. Repeat the process for channels CH2, CH3, and CH4 to verify their functionality.

When connecting a probe to any input channel for the first time, you must perform this adjustment to match the probe to the channel. An uncompensated probe can cause measurement errors.

1. Perform the first four steps of the “Function Inspection” procedure (connect the probe to the compensation signal output).

2. Compare the displayed waveform with the following compensation types:

• Over compensated: The square wave overshoots.

• Under compensated: The square wave is rounded.

• Perfectly compensated: The square wave has flat, horizontal tops.

3. Use a non-metallic screwdriver to adjust the variable capacitor on the probe until the waveform is “Perfectly compensated”. Repeat if necessary.

The front panel provides access to all major controls and inputs. The key areas are:

The rear panel provides connectivity for power, networking, and other peripherals.

The HANTEK HRDO4254D features a multi-touch capacitive screen supporting several gestures:

1. Tap: Tap a menu or function on the screen with one finger to operate menus, use the pop-up numeric keyboard, set file names, or close pop-up windows.

2. Drag: Press and hold a target, then drag it to the desired position. This can be used to change a waveform’s displacement/offset or to move a window.

3. Pinch & Stretch: Bring two fingers together or apart on the screen. Pinching horizontally adjusts the horizontal time base (zoom in/out), while pinching vertically adjusts the vertical scale.

4. Rectangle Drawing: Click the Hantek icon, then click AreaSel to enter this mode. Drag your finger to draw a rectangle on the screen. A menu will appear allowing you to select functions like “Histogram,” “Enlarge Level,” “Enlarge Vertical,” or “Enlarge Waveform” for the selected area.

For example, clicking [Help] and then [QuickAction] will pop up an explanation menu for the QuickAction function.

To Enable an Analog Channel (e.g., CH1):

• Click the channel status label at the bottom of the screen. The label will light up, and the corresponding front panel button [CH1] will also light up.

• Alternatively, press the [CH1] button on the front panel directly. The button and the light on the corresponding channel knob will turn on.

To Disable an Analog Channel:

• If the channel is currently selected, press its front panel button once to close it.

• If the channel is open but not selected, press its button once to select it, then press it again to close it.

• Use the touch screen to click the channel number on the channel menu at the bottom of the screen to close it.

To Adjust the Vertical Scale (V/div):

• Rotate the vertical gear knob for the corresponding channel. Rotate clockwise to decrease the V/div setting (zoom in) and counter-clockwise to increase it (zoom out).

• Alternatively, use the touch screen to click the channel menu at the bottom of the screen and set the vertical gear in the pop-up menu.

To Adjust the Vertical Offset:

• Rotate the vertical offset knob for the channel. This moves the waveform up or down on the screen. Press the knob to quickly reset the offset to zero.

• Use the touch screen’s drag gesture to move the waveform vertically.

• Click the channel menu at the bottom of the screen and set the offset value in the pop-up menu.

• Start Frame/End Frame: Define the range of frames to be played back.

3. Use the navigation keys in the horizontal control section to play, reverse, or stop the playback of the recorded waveform frames.

If the waveform appears “ladder-like,” try the following:

1. The horizontal time base might be set too slow. Increase the horizontal time base (faster sweep speed) to improve the display resolution.

2. If the display type is set to “Vector,” the lines drawn between sample points can sometimes cause this effect. Check the display settings.

Follow these troubleshooting steps:

1. Check if the main power switch of the oscilloscope is turned on.

2. Check if the fuse is intact. If the fuse needs to be replaced, ensure you use a replacement that meets the product’s specifications.

3. If the button board still does not light up, please contact Hantek technical support for assistance.

If you don’t see a signal, check the following:

1. Ensure the probe is correctly connected to the BNC connector of the signal input channel.

2. Check if the channel you are using (CH1-CH4) is turned on via the menu buttons.

3. Verify that the circuit you are testing is actually outputting a signal.

4. If it is a DC signal with a large amplitude, you may need to increase the vertical scale (V/div) to bring it into view.

5. Press the automatic measurement button ([Auto Scale]) to have the oscilloscope automatically detect and display the signal.

If a waveform is still not displayed, contact technical support.

If the touch screen is unresponsive, try these steps:

1. Check if the touch screen function has been disabled. Click the [Touch Lock] key in the button area to re-enable it.

2. Check for any dirt or debris on the screen or your fingers. Clean the screen if necessary.

3. Check if the oscilloscope is near a strong magnetic field, which can interfere with touch functionality. If so, move it away.

If the touch screen still does not work, please contact Hantek technical support.

If your USB drive is not recognized, check the following:

1. Ensure the USB drive itself is functioning correctly by testing it on another device.

2. Confirm the capacity of the USB flash drive. It is recommended to use a drive that does not exceed 16GB.

3. Confirm that the USB drive is formatted with the FAT32 file system.

4. Power cycle the oscilloscope and reinsert the USB drive to see if it is detected.

If the issue persists, contact Hantek Technical Support.
