3 Operation
WARNING
• Use this probe only with YOKOGAWA’s oscilloscopes. Even with YOKOGAWA’s
oscilloscopes, this probe can be used only when specified as an accessory.
• 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.
• When the oscilloscope’s input coupling is AC, a DC voltage is applied to the
oscilloscope’s input at the same electric potential as the probe’s input. Make sure not to
exceed the oscilloscope’s maximum input voltage.
• This probe cannot be used to measure the voltage between two points floating from the
ground potential. Consider using a differential probe.
• When disconnecting the probe BNC output connector, first turn OFF the power to the
circuit under measurement. Then, disconnect the probe from the high voltage parts of the
circuit under measurement.
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 dirt. Prevent damage to the probe. Avoid immersing the
probe, using abrasive cleaners, and using chemicals contains benzene or similar
solvents.

AVERTISSEMENT
• Utilisez la sonde uniquement avec les oscilloscopes de YOKOGAWA. Même avec les
oscilloscopes de YOKOGAWA, la sonde ne peut être utilisée que si spécifiée comme
accessoire.
• S’assurer d’éviter un choc électrique lors de la connexion de la sonde à l’objet de la
mesure. Ne pas retirer la sonde de l’instrument de mesure après avoir connecté l’objet
de la mesure.
• Lorsque le couplage d’entrée de l’oscilloscope est AC, une tension DC est appliquée
à l’entrée de l’oscilloscope au même potentiel électrique que l’entrée de la sonde.
Assurezvous de ne pas dépasser la tension d’entrée maximale de l’oscilloscope.
• La sonde ne peut être utilisée pour mesurer la tension entre deux points flottant du
potentiel de terre. Pensez à utiliser une sonde différentielle.
• Lors de la déconnexion du connecteur de sortie BNC de la sonde, mettre d’abord HORS
tension le circuit faisant l’objet de la mesure. Puis déconnecter la sonde des parties à
haute tension du circuit faisant l’objet de la mesure.
ATTENTION
• Évitez les chocs sur le corps de la sonde. Ne pliez pas et ne tirez pas les câbles de
manière excessive. Cela pourrait endommager ou déconnecter la sonde.
• Utiliser un chiffon doux pour nettoyer la sonde. Faire attention de ne pas casser la sonde.
Ne pas immerger la sonde dans un liquide ni utiliser de nettoyants abrasifs sur la sonde.
Ne pas utiliser de benzène ni d’autres solvants sur la sonde.
How to Connect the Probe
1.
Connect the BNC connector of the probe to the input of the oscilloscope with the input
impedances of 1 MΩ. Set the input impedance of the oscilloscope to 1 MΩ.
2.
The probe ID pin is automatically detected, and the oscilloscope attenuation ratio is automatically
set to 10:1. If it is not set automatically, set it manually.
3.
Use adequate attachment suitable for the point to measure.
How to Adjust the Probe Phase
CAUTION
Do not apply excessive force to the phase adjustment screw. Doing so may damage the
internal variable capacitor.
ATTENTION
N’appliquez pas une force excessive sur la vis de réglage de phase. Cela pourrait
endommager le condensateur variable interne.
1.
Connect the probe connector to the input of the oscilloscope, and connect the tip of the probe to
the CAL signal output terminal.
2.
Change the T/Div and the V/Div to get the display shown below. And tune the trimmer to get the
correct waveform.

Note
Accurate measurement may not be possible near objects with strong electric fields (such as
cordless equipment, transformers, or circuits with large currents).

3 This equipment is for measurement category II (CAT II). Do not use it with measurement category III (CAT
III), nor measurement category IV (CAT IV). When using devices or accessories with different measurement
categories, the lower measurement category applies. See below for definitions of measurement categories.
Measurement Category
Definition
Measurement category “O
(Other)”
Measurement category O (Other) applies to measurement of a
circuit that is not connected directly to the main power source.
Measurement category II
(CAT II)
CAT II applies to measurement of electrical equipment that is
powered through a fixed installation such as a wall outlet wired to
a distribution board and measurement on such wiring.
Measurement category III
(CAT III)
CAT III applies to measurement at the distribution level, that is,
building wiring, fixed installations.
Measurement category IV
(CAT IV)
CAT IV applies to measurement at the primary supply level, that
is, overhead lines, cable systems.
4 Pollution degree applies to the degree of adhesion of a solid, liquid, or gas which deteriorates withstand
voltage or surface resistivity. Pollution degree 2 applies to normal indoor atmospheres (with only non-
conductive pollution).
