CT4432 10 kV High-Voltage Oscilloscope Probe User Manual
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 confirming 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
le fil de la pince de masse crocodile.
Do not exceed 60 seconds of contact between the probe and the circuit-under-test
when measuring voltages ≥8 kV DC, ≥5 kV ACrms, or ≥15 kVpk-pk AC. It is recom
-
mended to wait 5 minutes between measurements.
