YOKOGAWA DLM3052 (02) PDF SUMMARY:

What should I prepare to use the instrument according to the workflow?

• The instrument (the DLM3054 is used as an example in the PDF).
• A power cord that complies with the standard specified by the country or region that the instrument will be used in.
• Included passive probe (701937).
• Printed Operation Guide (IM DLM3054-04EN).
• Getting Started Guide (IM DLM3054-03EN).
• PDF data (contained in the CD): Features Guide & Users Manual.pdf, Features Guide (IM DLM3054-01EN), and User’s Manual (IM DLM3054-02EN).
• Adjustment screwdriver (used in the phase correction of probes).

Where can I find handling precautions and warnings of this instrument?

The handling precautions and warnings can be found in the Getting Started Guide (IM DLM3054-03EN).

---

What are the steps for measurement preparation?

1. Turn on the power switch. (See section 2.3, “Connecting the Power Supply and Turning the Power Switch On and Off,” in the Getting Started Guide).
2. Connect a probe to the instrument’s input terminal (CH1). (See section 2.4, “Connecting Probes,” in the Getting Started Guide).
3. Correct the probe phase. (See section 2.5, “Correcting a Probe Phase,” in the Getting Started Guide).

How do I display the waveform using auto setup?

Use the instrument’s probe compensation signal (frequency: approx. 1 kHz, amplitude: approx. 1 V, square wave signal) for the input signal.

1. Press AUTO to execute auto setup.

When auto setup is executed, the voltage scale (V/div), time scale (Time/div), trigger level, and the like are automatically set to values suitable for the input signal.

The auto setup feature may not work properly for signals that include a DC component or high-frequency components. To measure the voltage with high accuracy, adjust the vertical scale so that the input signal is measured with the largest possible amplitude.

How do I change the vertical axis settings?

Change the vertical scale (voltage sensitivity) from 500 mV/div to 200 mV/div to increase the waveform amplitude. Setting the voltage sensitivity means setting the voltage per grid division (V/div).

1. Press CH (1).
2. Use the SCALE knob to change the voltage sensitivity to 200 mV/div.

The waveform is expanded vertically causing a portion of the waveform to go off the screen. Measurements may not be performed correctly in this condition. Lower the vertical position so that the entire waveform can be seen.

3. Use the POSITION knob to move the vertical position down by 2 divisions.

Lowering the vertical position causes the entire waveform to be seen. The ground level also moves along with the waveform.

For details on the vertical axis, see chapter 1, “Vertical Axis (Analog Signal),” in the Features Guide (IM DLM3054-01EN).

---

How do I change the horizontal (time) scale?

Change the horizontal (time) scale from 200 µs/div to 100 µs/div. Setting the time scale means setting the time per grid division.

1. Use the TIME/DIV knob to change Time/div to 100 µs/div.

For details on the horizontal axis, see chapter 3, “Horizontal Axis (Time Axis),” in the Features Guide (IM DLM3054-01EN).

How do I move the trigger position on the screen?

You can move the trigger position on the screen to change the display ratio of the data previous to the trigger point (pre-trigger section) and the data after the trigger position (post-trigger section).

1. Use the POSITION to move the trigger position to the left by 2 divisions. The trigger position is set to 30%.

The waveform moves to the left causing more of the waveform after the trigger (post-trigger section) to be seen.

For details on triggers, see chapter 4, “Trigger,” in the Features Guide (IM DLM3054-01EN).

---

How do I change the edge trigger settings?

Edge triggers are simple triggers that are activated when the trigger source passes through a trigger level. A change in the waveform that causes it to pass through a trigger level is called an edge. When you execute auto setup, the edge trigger is automatically set.

---

How do I change the trigger slope from rising to falling?

Use the slope to set the direction of the edge. There are two edge directions: rising (movement from a low level to a high level) and falling (movement from a high level to a low level). Setting the slope allows triggers to be activated on the rising edge, falling edge, or both.

1. Press EDGE.
2. Press the Slope soft key to select (falling). The instrument will trigger on the falling edges of the trigger source.

---

How do I measure the waveform?

Use vertical cursors (ΔT cursors) to measure the time and voltage of the displayed waveform.

1. Press CURSOR.
2. Press the Type soft key to select (ΔT cursor). Two vertical cursors, the times (T1, T2) and voltages (V1, V2) at the cursor positions, and other measurements are displayed.
3. Turn the jog shuttle to move a cursor. The cursor that the jog shuttle controls switches each time you press SET. You can also select both T cursor 1 and T cursor 2.

How do I save the waveform screen image?

You can save screen captures. The available data formats are PNG, BMP, and JPEG.

1. Press SHIFT + PRINT.
2. Press the Print To soft key to set the output destination to File.
3. Use the Format soft key to set or view the data format, the File List soft key to set or view the save destination, and the File Name soft key to set or view the file name.
4. Press PRINT. A screen capture is saved.

For details on saving screen captures, see chapter 16.5, “Saving Screen Captures to Files,” in the User’s Manual (IM DLM3054-02EN). To use the built-in printer (option), change Print To to BuiltIn.
