1 Overview
Model 700929 is a dedicated 10:1 safety probe supporting isolated input that enables safer, high-
voltage measurement when used in combination with an isolated input measuring instrument
(waveform measuring instrument). The probe body and the BNC connector, except for the probe tip,
are isolated so that dangerous voltages cannot be accidentally exposed. Make sure that you also
fully understand the conditions for using the measuring instrument when using the probe.
2 Configuration
The 700929 consists of a probe unit and its standard accessories.

3 How to Use
WARNING
• Use this probe only with YOKOGAWA’s isolated input measuring instruments. Even with
YOKOGAWA’s measuring instruments, this probe can be used only when specified as an
accessory.
• Do not apply a voltage exceeding the maximum input voltage or the derating voltage by
frequency to the probe. EN61010-031 is a compliant safety standard that is applied to
the probe alone. For the actual safety standards and operating conditions, comply with
the conditions of the measuring instrument. Failure to follow this precaution may cause
accidents, such as electric shock or damage to the measuring instruments.
• The actual maximum input voltage is limited to the lower of the maximum input voltage of
the probe or the maximum input voltage of the measuring instrument. For the maximum
input voltage of the measuring instrument, see the specifications of the measuring
instrument. Convert the attenuation ratio of the probe and make sure not to apply
excessive input voltage to the measuring instrument.
• When the input coupling of the measuring instrument is AC, a DC voltage is applied to
the measuring instrument’s input at the same electric potential as the probe’s input. Make
sure not to exceed the maximum input voltage of the measuring instrument.
• When disconnecting the probe, turn off the power to the device under measurement,
disconnect the probe from the device, and then disconnect the probe from the measuring
instrument.
CAUTION
• Avoid shock to the probe body. Do not bend or pull the cables excessively. Doing so may
damage or disconnect the probe.
• Use a soft cloth to clean the probe. Do not immerse the probe body in liquid. Do not use
abrasive cleaners or volatile solvents such as benzine on the probe.
