1. Overview
The 702902 is a 10:1 passive probe that provides high-voltage measurement when used together
with an isolated input measuring instrument. It can be used over a wide temperature range (–40°C
to +85°C). Except for the tip of the probe, the probe and BNC connector are isolated so that
dangerous voltages are not accidentally exposed. Make sure you also fully understand the correct
use of the measuring instrument when using the probe.

1.
Connect the probe connector to the input of the isolated-input measuring instrument, and
connect the tip of the probe to the signal output terminal for phase adjustment (CAL or COMP
terminal) of the measuring instrument.
2.
Control the vertical and time scales on the isolated-input measuring instrument, and adjust to
obtain the correct waveform (square waveform) as shown below by turning the groove of the
phase adjustment knob with an off-the-shelf Phillips screwdriver (#0)*.
* A driver is not included. Use a ceramic screwdriver or other non-metallic screwdriver.

6 The instrument is for measurement category II (CAT II). Do not use it with measurement
category III (CAT III), nor measurement category IV (CAT IV). The measurement category varies
depending on the accessory. When using devices or accessories with different measurement
categories, the lower measurement category applies.
Measurement Category Definition
Measurement category “O” (Other) It applies to measurement of a circuit that is not
connected directly to the main power source.
Measurement category II (CAT II) It 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) It applies to measurement at the distribution level, that
is, building wiring, fixed installations.
Measurement category IV (CAT IV) It applies to measurement at the primary supply level,
that is, overhead lines, cable systems.
7 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
(usually with only non-conductive pollution).
8 For conformity to environmental regulations and/or standards other than EU, contact your
nearest Yokogawa office (PIM 113-01Z2).

• EN 61010-031 is a safety standard that applies to the probe alone. For the actual
compliant safety standards and operating conditions, observe the conditions for the
measurement instrument. Failure to observe them may cause accidents, such as electric
shock and damage to the instrument.
• When the measuring instrument’s input coupling is AC, DC voltage of the same electric
potential as the probe’s input is applied to the measuring instrument’s input. Make sure
not to exceed the measuring instrument’s maximum input voltage.
• After use, turn off the power to the device under measurement, disconnect the probe
from the device under measurement, and then disconnect the probe from the measuring
instrument.
CAUTION
• When using optional tip accessories (such as alligator clip adapters) sold separately,
make sure to use the 4Φ conversion adapters sold separately in between. Optional tip
accessories are unavailabe without the 4Φ conversion adapters.
• The product is not dust proof or water resistant. Do not use the product in areas with a lot
of dust or where water may be spilled.
• Avoid using or storing the product in an environment that does not meet the specifications
such as under direct sunlight, high temperature, high humidity, or where condensation
may form. Deformation and insulation deterioration can occur to cause the probe to no
longer meet the specifications.
• Avoid vibration, shock, and static electricity when handling the probe. Do not bend or pull
the cables excessively. Doing so may damage or disconnect the probe.
• When cleaning the probe, wipe with a piece of soft cloth to prevent damaging the probe.
Do not immerse the probe body in liquid. Do not use abrasive cleaners or volatile solvents
such as benzine on the probe.
French
AVERTISSEMENT
• Utilisez la sonde uniquement avec l’instrument de mesure à entrée isolée de
YOKOGAWA. Et la sonde ne peut être utilisée que lorsqu’elle est spécifiée comme
accessoire pour l’instrument de mesure à utiliser.
• Lors de la connexion de la sonde à l’objet faisant l’objet de la mesure, faire attention au
choc électrique, aux brûlures et aux gelures.
• Ne pas appliquer une tension dépassant un pic de 1000 V entre une pointe de pince et
un fil de terre de sécurité ou entre un fil de terre de sécurité et la terre.
• EN 61010-031 is a safety standard that applies to the probe alone. For the actual
compliant safety standards and operating conditions, observe the conditions for the
measurement instrument. Failure to observe them may cause accidents, such as electric
shock and damage to the instrument.
• Lorsque le couplage d’entrée de l’instrument de mesure est en CA, la tension en CC du
même potentiel électrique que l’entrée de la sonde est appliquée à l’entrée de l’instrument
de mesure. S’assurer de ne pas dépasser la tension d’entrée maximum de l’instrument
de mesure.Observe the maximum input voltage.
• Après utilisation, coupez l’alimentation de l’appareil en cours de mesure, déconnectez la
sonde de l’appareil en cours de mesure, puis déconnectez la sonde de l’instrument de
mesure.
ATTENTION
• Lorsque vous utilisez des accessoires de pointe en option (tels que des adaptateurs
de pince crocodile) vendus séparément, assurez-vous d’utiliser les adaptateurs de
conversion 4Φ vendus séparément entre les deux. Les accessoires de pointe en option
ne sont pas disponibles sans les adaptateurs de conversion 4Φ.
• Le produit n’est pas étanche à la poussière ni à l’eau. N’utilisez pas le produit dans des
zones très poussiéreuses ou dans lesquelles de l’eau pourrait être renversée.
• Évitez d’utiliser ou de stocker le produit dans un environnement qui ne répond pas aux
spécifications, par exemple sous la lumière directe du soleil, à des températures élevées,
à une humidité élevée ou là où de la condensation peut se former. Une déformation et
une détérioration de l’isolation peuvent survenir, faisant que la sonde ne répond plus aux
spécifications.
• Évitez les vibrations, les chocs et l’électricité statique lors de la manipulation du produit.
Ne pliez pas et ne tirez pas les câbles de manière excessive. Cela pourrait endommager
ou déconnecter la sonde.
• Lors du nettoyage de la sonde, essuyez avec un morceau de chiffon doux pour éviter
d’endommager la sonde. Ne plongez pas le corps de la sonde dans un liquide. N’utilisez
pas de nettoyants abrasifs ni de solvants volatils tels que la benzine sur la sonde.
How to Connect
1.
Connect the probe connector to the input of the isolated-input measuring instrument.
2.
Depending on the object under measurement or the situations, connect the attached pincher tip
and safety ground lead to the tips of the probe, or connect the optional accessories by putting
the optional 4Φ conversion adapters (signal end / ground) in between. See Connecting the
Optional Accessories for details.
3.
Adjust the phase of the probe using the screwdriver. See Phase Adjustment for details.
Connecting the Optional Accessories
If you use the optional 4Φ conversion adapters (signal end B8099NL / ground B8099NM, 1000
Vpeak CAT II) instead of the attached pincher tip (B8099NJ) and safety ground lead (B8099NK),
you can connect to the following optional tip accessories. We offer a variety of combinations.
Contact your nearest YOKOGAWA dealer for details.
• Optional pincher tip (B9852MN/B9852MM, 1000 Vrms CAT III)
• Alligator clip adapter (758929, 1000 Vrms CAT II)
• Fork terminal adapter (758921, 1000 Vrms CAT II)
