3. How to Use
•
Turn off the power to the circuit under measurement when you connect or disconnect
the probe from the circuit. Connecting or removing the probe while the power is on
is dangerous. Do not touch the probe after turning on the power to the circuit under
measurement.
•
Do not disconnect the probe's BNC connector from the oscilloscope while the probe is
connected to the circuit under measurement. Before disconnecting the BNC connector,
turn off the power to the circuit under measurement, and disconnect the probe from the
high voltage parts of the circuit.
•
This probe is designed to measure the voltage difference between two points on the
circuit under measurement. It does not electrically isolate the circuit under measurement
from the measuring instrument.
•
Use a soft cloth to clean the probe. Be careful not to break the probe.
Do not immerse the probe in liquid or use abrasive cleaners on the probe. Do not use
benzene or other solvents on the probe.
Preparation
1.
Have the probe and an oscilloscope with the probe IF ready.
2.
Insert the probe interface completely into the oscilloscope input, and confirm that the BNC
connector and interface pin are securely fastened. You will hear the latch click when the
connectors lock into place.
3.
When you connect the probe to an oscilloscope with the probe IF, the attenuation ratio and
input coupling on the oscilloscope are set automatically. If you change the attenuation ratio
of the probe using the attenuation switch, the attenuation ratio on the oscilloscope changes
automatically.
4.
If necessary, attach the provided extension leads, pincher tips, and resistance adapters to the
input leads.
Connecting Accessories
If you are using input leads and pincher tips, use the 100 Ω resistance adapters.

If you are connecting extension leads (1 m) to input leads, use the 150 Ω resistance adapters.

150 Ω resistance adapters (green)
Note
•
Accurate measurements may not be possible near objects with strong electromagnetic fields
such as transformers, large current circuits, and wireless equipment.
•
Before use, flip the attenuation switch back and forth several times. The switch's electrical
contacts can weaken if not used for long periods of time.
•
To take accurate measurements, we recommend that you calibrate the probe once a year.

8 This product is for measurement category II (CAT II). Do not use it for measurement category III
(CAT III) or IV (CAT IV). When using devices with different measurement categories, the lower
measurement category applies. Because the measurement category of the probe is lower than
its accessories, when the probe and its accessories are used together, measurement category II
(CAT II) applies.
