Usage Precautions
The high-voltage probe is designed to prevent accidental shock to the operator when
properly used. This operating note must be read and understood prior to using the
probe. Improper procedure or incorrect analysis of the measurement situation can
result in serious shock.
La sonde haute tension est conçue pour éviter les chocs accidentels à l’opérateur
lorsqu’elle est correctement utilisée. Cette notice d’utilisation doit être lue et comprise
avant d’utiliser la sonde. Une procédure incorrecte ou une analyse incorrecte de la
situation de mesure peut entraîner un choc grave.
This high-voltage probe must only be used by personnel who are trained, experienced,
or otherwise qualied to recognize hazardous situations and who are trained to the
safety precautions that are necessary to avoid possible injury when using such a de-
vice.
Cette sonde haute tension ne doit être utilisée que par du personnel formé, expéri-
menté ou autrement qualié pour reconnaître les situations dangereuses et qui est
formé aux précautions de sécurité nécessaires pour éviter les blessures possibles lors
de l’utilisation d’un tel appareil.
When measuring higher frequency signals, be sure to comply with the Voltage vs
Frequency Derating Curve. Do not apply to the input any potential that exceeds the
maximum rating of the probe.
Lors de la mesure de signaux de fréquence plus élevée, assurez-vous de respecter la
courbe de déclassement tension/fréquence. N’appliquez à l’entrée aucun potentiel qui
dépasse la valeur nominale maximale de la sonde.
This high-voltage probe is designed for use with Measurement Category other than
II, III and IV only (formally CAT I). Do not use the probe for measurements performed
on circuits dened by any other measurement category or transient overvoltages of
more than 1500 V. Refer to IEC Measurement Category Denitions on page 9 for a
denition of measurement categories.
Cette sonde haute tension est conçue pour être utilisée avec des catégories de
mesure autres que II, III et IV uniquement (anciennement CAT I). N’utilisez pas la
sonde pour des mesures effectuées sur des circuits dénis par une autre catégorie de
mesure ou des surtensions transitoires de plus de 1 500 V. Reportez-vous à Déni-
tions des catégories de mesure CEI à la page 9 pour une dénition des catégories
de mesure.
The ground lead is critical to the safe operation of the probe. Failure to make this
connection when making high-voltage measurements may result in personal injury or
damage to the probe or oscilloscope. This connection must always be made BEFORE
the probe tip comes in contact with the high voltage and must not be removed until the
probe tip has been removed from the high-voltage source.

Optional Accessory
For connecting the probe to a Digital Multimeter (DMM) you can use the CT3197B High-Voltage Probe
BNC Converter. The high-voltage probe converter allows impedance matching of the probe’s 1 MΩ out-
put to a DMM’s 10 MΩ input. Usable with most quality DMMs, you can order this converter separately.

Measurement Instructions
Before connecting the probe for your measurement, read all the warnings in this section and all of the
warnings in the section “Safety Information” on page 6.
Frequency compensate the probe to your oscilloscope prior to usage. See “Frequency Compensation”
on page 14.
Steps
1. Whenever possible, turn the high-voltage source off before making any connections.
2. Connect the alligator ground clip lead to a good earth ground or reliable chassis ground.
3. Connect the probe’s BNC connector to the oscilloscope’s BNC output.
4. On the oscilloscope, select the desired volts/division range. If the oscilloscope has probe attenua-
tion ration setting, set it to 1000:1, if available.
Before turning on the high voltage source, make sure that no part of the person holding
the prove is touching the device under test.
Avant d’allumer la source haute tension, assurez-vous qu’aucune partie de la per-
sonne tenant la preuve ne touche l’appareil à tester.
5. After conrming that the probe operator is not touching the device under test, turn on the high-volt-
age source.
6. Measure the voltage under test and observe the waveform on the oscilloscope.
Remember the actual voltage is 1000 times greater than the oscilloscope waveform if
the probe attenuation has not been set to 1000:1.
N’oubliez pas que la tension réelle est 1000 fois supérieure à la forme d’onde de l’os-
cilloscope si l’atténuation de la sonde n’a pas été réglée sur 1000:1.
7. Turn off the high voltage source.
8. Disconnect the probe tip from the high-voltage source.
9. Disconnect the probe’s ground clip lead.
Disconnect the probe tip from the high voltage source BEFORE disconnecting the
alligator ground clip lead.
Déconnectez la pointe de la sonde de la source haute tension AVANT de déconnecter

Frequency Compensation
Use the following frequency compensation adjustments to compensate the probe for the oscilloscope’s
input capacitance. You should preform this adjustment whenever you connect the probe to a different
oscilloscope input channel or to a different oscilloscope.
Low Frequency Compensation Adjustment
1. Connect the probe to the oscilloscope.
2. Connect the probe tip to a square-wave function generator.
3. Adjust the function generator’s output to square-wave, 200 Hz frequency and 10 V amplitude.
4. Adjust the oscilloscope time base for approximately 2 ms/div so that you can see several waveform
cycles.
5. Using supplied trimmer tool, adjust the Low Frequency Adjustment Point (Figure 5) for the attest
square-wave top. Figure 6 shows the correctly compensated waveform.
