Safety Precautions
This is an IEC safety class I instrument (with protective grounding).
The following general safety precautions must be taken during all phases of operation,
service, and repair of this instrument. If this instrument is used in a manner not specified
in this manual, the protective features provided by the instrument may be impaired. Also,
Yokogawa Electric Corporation assumes no liability for the customer’s failure to comply
with these requirements.
The following symbols are used on this instrument.
Danger. Refer to the user’s manual.
This symbol appears on dangerous
locations on the instrument which require special instructions for proper
handling or use. The same symbol appears in the corresponding place in the
manual to identify those instructions.
Functional ground terminal (not to be used as a protective ground terminal).

IM 701730-01E
Make sure to comply with the precautions below. Not complying might result in injury
or death.
WARNING
Use the Correct Power Supply
Before connecting the power cord, ensure that the source voltage matches the
rated supply voltage of the instrument and that it is within the maximum rated
voltage of the provided power cord.
Use the Correct Power Cord and Plug
To prevent the possibility of electric shock or fire, be sure to use the power cord
supplied by YOKOGAWA. The main power plug must be plugged into an outlet
with a protective earth terminal. Do not disable this protection by using an
extension cord without protective earth grounding.
Connect the Protective Grounding Terminal
Make sure to connect the protective earth to prevent electric shock before
turning ON the power. The power cord that comes with the instrument is a
three-prong type power cord. Connect the power cord to a properly grounded
three-prong outlet.
Do Not Impair the Protective Grounding
Never cut off the internal or external protective earth wire or disconnect the
wiring of the protective earth terminal. Doing so poses a potential shock hazard.
Do Not Operate with Defective Protective Grounding or Fuse
Do not operate the instrument if the protective earth or fuse might be defective.
Make sure to check them before operation.
Fuse
To prevent a fire, make sure to use fuses with the specified standard (voltage,
current, type). Before replacing the fuses, turn off the power and disconnect the
power source. Do not use a different fuse or short -circuit the fuse holder.
Do Not Operate in an Explosive Atmosphere
Do not operate the instrument in the presence of flammable liquids or vapors.
Operation in such environments constitutes a safety hazard.
Do Not Remove Covers
The covers should be removed by YOKOGAWA’s qualified personnel only.
Opening the cover is dangerous, because some areas inside the instrument
have high voltages.
Ground the Instrument before Making External Connections
Securely connect the protective grounding before connecting to the item under
measurement or an external control unit. If you are going to touch the circuit,
make sure to turn OFF the circuit and check that no voltage is present.
To prevent the possibility of electric shock or an accident, connect the ground of
the probe and input connector to the ground of the item being measured.
See below for operating environmental limitations.
CAUTION
This product is a Class A (for industrial environments) product. Operation of this
product in a residential area may cause radio interference in which case the
user will be required to correct the interference.

Notations Used on Pages Describing Operating Procedure
On pages that describe the operating procedures in Chapter 3 through 16, the following
notations are used to distinguish the procedures from their explanations.
Procedure
Carry out steps in the order shown. The operating procedures are
given with the assumption that you are not familiar with the
operation. Thus, it may not be necessary to carry out all the steps
when changing settings.
Explanation
Describes settings and restrictions relating to the operation. A
detailed description of the function is not provided. For a detailed
description of the function, refer to Chapter 2.
Notations Used in the Procedure
Panel Keys and Soft keys
Bold characters used in the procedural explanations indicate characters that are marked on the
panel keys or the characters of the soft keys displayed on the screen menu.
SHIFT+Panel Key
SHIFT+key means you will press the SHIFT key (causing the green indicator to the left of the
SHIFT key to illuminate), and then press a panel key. The setup menu marked in purple above
or below the panel key that you pressed appears on the screen.
Jog Shuttle & SELECT
Jog shuttle & SELECT indicates selecting or setting parameters and entering values using the jog
shuttle, the SELECT key, and other keys. For details on the procedure, see section 4.1 or 4.2.

V DIV
CH1 to CH4* Keys (Sections 5.1 to 5.10, and 8.9)
Each key displays a menu used to turn ON/OFF the channel’s display and set the
vertical position, coupling, probe attenuation/current-to-voltage conversion ratio, offset
voltage, bandwidth limit, expansion or reduction of the vertical axis, linear scaling, and
waveform labels.
If you press a CH key before operating the V/DIV knob to display the menu for the
channel, the channel becomes controllable using the V/DIV knob.
The indicator to the left of each CH key illuminates when the channel is ON.
* There are two channel keys (CH1 and CH2) on the DL1720E and four channel keys (CH1 to
CH4) on the DL1735E/DL1740E/DL1740EL. The notation CH1 to CH4(2) is used in this
manual to indicate that CH1 to CH2 or CH1 to CH4 can be controlled or configured on the
DL1720E and the DL1735E/DL1740E/DL1740EL, respectively.
Note
The setup menu used to specify whether the offset voltage is applied to the measured and
computed results is located in the menu that appears when the MISC key (see section 1-7) is
pressed.
V/DIV Knob (Section 5.2)
Sets the vertical sensitivity*.
Before turning this knob, press one of the CH1 to CH4(2) keys to show the menu for
the channel and have the channel selected.
If you change the vertical sensitivity setting when waveform acquisition is stopped, the
new setting takes effect when you restart waveform acquisition.
* In the attenuation/current-to-voltage conversion ratio setting of the probe, if the probe
attenuation is specified, the voltage sensitivity is set. If the current-to-voltage conversion ratio
is specified, the current sensitivity is set.
PRESET Key (Section 5.7)
Displays a menu used to automatically set the probe attenuation/current-to-voltage
conversion ratio, V/div, offset voltage, trigger level, and other parameters to the
optimum values for CMOS or ECL signals (or to arbitrary values).
Presets can also be applied to all channels at once.

TIME/DIV Knob (Section 5.11)

Displays a menu used to set the zoom display of waveforms.
SHIFT+ZOOM (SEARCH) Key (Section 10.4)
Displays a menu used to set waveform searches (Search and Zoom function).
