Safety Precautions

Make sure to comply with the safety precautions mentioned hereafter when handling this instrument.
YOKOGAWA ELECTRIC Co. assumes no responsibility for any consequences resulting from failure to comply
with these safety precautions. Also, read the User's Manual of the measuring instrument thoroughly so that you
are fully aware of its specifications and handling, before starting to use the probe.

• General definitions of safety symbols and markings

This symbol indicates the risk of injury, death of personnel or damage to the instrument.
Be sure to refer to the corresponding explanation in the User's Manual.

CAUTION

CAUTION

• Make sure to comply with the following safety precautions in order to prevent accidents such as an
electric shock which impose serious health risks to the user and damage to the instrument.

WARNING • Grounding of the measuring instrument

This symbol calls attention to a procedure, practice, condition or the like, which, if not
correctly performed or adhered to, could result in injury or death of personnel.

This symbol calls attention to a procedure, practice , condition or the like, which, if not
correctly performed or adhered to, could result in damage to or destruction of part of the
product.

Make sure to connect the protective grounding of the measuring instrument.

• Connecting the object of measurement

Make sure to avoid an electric shock when connecting the probe to the object of
measurement. Do not remove the probe from the measuring instrument after the object
of measurement is connected.

CAUTION • Nondestructive input voltage range

Do not apply any voltages exceeding the Nondestructive input voltage range to the probe.

• Maximum input voltage

Do not supply any voltages exceeding the maximun input voltage to the probe.

Overview

The 700929 is a 10:1 probe that provides safer, high-voltage measurement when used together with an isolated
input measuring instrument (waveform measuring instrument or amplifier). The probe and BNC connector are
isolated so that dangerous voltages are not accidentally exposed when the probe is removed from the
measurement terminal. Make sure you also fully understand the correct use of the instrument when using the
probe.

Contents of the Package

The probe, safety clip lead, and safety plug-on clip (B9940WX) should be included in the package.
Ceck that all contents are present and that they are undamaged.

* : Probe alone

• The actual maximum input voltage is limited to the lesser of either the probe's maximum input
voltage or the measuring instrument's input voltage.

• See the specifications of the measuring instrument you are using to determine the maximum input
voltage.

• Convert the probe's attenuation ratio, and be sure not to input an excessive voltage to the
measuring instrument.

• If a voltage exceeding the maximum input voltage or frequency deleting is applied, damage to the
instrument may result.

(greater than –3 dB)

When the input voltage is AC, the maximum allowable input decreases depending on
the frequency as shown by the deleting curve in the chart below.

CAUTION

WARNING

EN61010-031 is the safety rating for the probe alone.
During actual use, you should adhere to the safety ratings and usage precautions of your measuring
instrument. Failure to comply with the correct safety precautions may result in electric shock or
damage to the instrument.

Using the Probe

Fasten the probe's connector to the instrument you are using (such as an oscilloscope), and connect the probe tip
to the CAL or COMP terminal on the instrument. When measuring with the probe, rotate the variable condenser
and adjust it until the correct waveform is generated as shown in the figure below.
