Safety Precautions
Make sure to observe the following safety precautions when handling the probe. Yokogawa Electric
Corporation assumes no liability for the customer’s failure to comply with these safety precautions.
Before you use the probe, read the measuring instrument’s manual to fully aware of its specifications
and handling.
The following symbols are used on this instrument.
Warning: handle with care. Refer to the user’s manual or service 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.
Risk of electric shock
Make sure to observe the following safety precautions to prevent electric shock, personal
injury, or damage to the instrument.
WARNING
Ground the measuring instrument
Make sure to connect the protective grounding terminal of the measuring instrument to
ground.
Connect the probe earth cable
Connect the probe earth cable to ground (grounding potential).
Stop use if you suspect damage
If you suspect that the probe is broken, consult your nearest YOKOGAWA dealer.
Observe the maximum input voltage
Do not apply voltage exceeding 7000 Vpeak between an input lead and ground or between
two input leads. The maximum input voltage is 7000 Vpeak regardless of whether 1000:1 or
100:1 attenuation is used.
Ground the probe
Ground the probe by connecting the grounding conductor of the measuring instrument’s
power cable or another appropriate grounding conductor to the BNC shell and an auxiliary
grounding terminal.
Before connecting the probe input terminal to the circuit under measurement, ensure that the
measuring instrument is grounded properly, that the probe output connector is attached to
the BNC connector of the measuring instrument, and that the auxiliary grounding terminal is
connected to a proper ground.
Do not remove the alligator clip’s cover
To prevent electric shock or fire, do not remove the alligator clip’s insulation cover.
Do not use in damp places
To prevent electric shock, do not use the probe in damp places.
Do not use in an explosive atmosphere
To prevent fire and injury, do not use the probe in a flammable or explosive atmosphere or
near steam.
Do not touch exposed circuitry
To prevent injury, remove metallic objects and jewelry such as rings and watches. Do not
touch exposed live connections or components.
CAUTION
Use the correct power supply
Power the probe by using four AA dry cells, by using a 6 VDC/200 mA or 9 VDC/150 mA
external power supply, or by connecting a probe power cable to the DL Series probe power
supply terminal, the 700938, or the 701934. Operating the probe while using a power supply
exceeding the specified voltage may cause damage to the instrument.
Turn OFF the probe when connecting an external power supply
Turn the probe power switch OFF when connecting or disconnecting from the external power
supply.
Do not install AA batteries when using an external power supply.
The following symbols are used in this manual.
Improper handling or use can lead to injury to the user or damage to the instrument.
This symbol appears on the instrument to indicate that the user must refer to the
user’s manual for special instructions. The same symbol appears in the corresponding
place in the user’s manual to identify those instructions. In the manual, the symbol is
used in conjunction with the word “WARNING” or “CAUTION.”
WARNING Calls attention to actions or conditions that could cause serious or fatal injury to the
user, and precautions that can be taken to prevent such occurrences.
CAUTION Calls attention to actions or conditions that could cause light injury to the user or
damage to the instrument or the user’s data, and precautions that can be taken to
prevent such occurrences.
Note Calls attention to information that is important for proper operation of the instrument.
Operating environment limitations
See below for operating environment 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.
Thank you for purchasing the High Voltage Differential Probe (701926) for the DL Series. To ensure
correct use, please read this manual thoroughly before beginning operation.
After reading this manual, keep it in a safe place.

4. Installing or Replacing Batteries
Slide the lid on the back side of the probe, and install or replace the four AA dry cells.
The probe is shipped from the factory without the batteries installed.
5. Procedure
1. Connect the provided high voltage alligator clips to the probe input leads.
2. Supply power to the probe by one of the following methods.
• Install four AA cells.
The power LED blinks if the battery level goes low. If this message appears, replace the dry
cells.
• Connect the appropriate power cable to an external power supply.
• Connect the probe power cable to a probe power supply terminal on the DL Series, the
700938, or the 701934.
3. Connect the BNC output connector to the oscilloscope input terminal, and properly ground the
auxiliary ground terminal. If necessary, use the auxiliary ground extension lead.
4. Turn the power switch ON, and warm up the probe for at least 30 minutes.
5. Select the appropriate attenuation using the attenuation ratio selector.
• For higher resolution and less noise when measuring signals less than or equal to 700 V,
switch the attenuation to 1/100.
• When measuring signals greater than 700 V, set the attenuation to 1/1000.
6. If the offset voltage is large, short the alligator clips, and turn the ADJUST variable resistor (DC
voltage adjustment) using an appropriate flat-head screwdriver to adjust the offset voltage.
7. Connect the two probe input leads to the two points of measurement (differential measurement).
The performance declines if you only connect a probe input lead to a single point. Make sure to
connect both leads.
