To Use the Probe
Before using the current probe, make sure to refer to
Safety Precautions
.
Preparation for Measurement
1.
Evaluate the amplitude of the voltage under test and check whether it is
within the voltage range of the probe. If it is beyond the max. range of the
probe, please replace a proper probe. Otherwise, the measurement would
be incorrect or the probe may be damaged. Even worse, this may lead to
safety accidents.
2.
Prepare one power adapter (DC 5 V, 1 A).
3.
Connect the probe to power source and have a 20-minute warm-up at
least. Meanwhile, prepare one measuring instrument (e.g. an
oscilloscope).
4.
Please ensure that the device under test is powered off or the output is
disabled.
Measurement Steps
Check and ensure that the measurement system is safe. Make sure that the
above preparation for measurement is ready.
1.
Connect the output cable of the probe to the input terminal of the
measuring instrument.
2.
Use the USB Type-C cable to connect its one end to the specified power
adapter and the other end to the power interface of the probe. Insert the
power adapter into the socket to provide power to the probe. If the
indicators on the panel light on normally, it indicates that the probe has
been launched normally.
3.
Select a proper range for the probe based on the measuring voltage.
4.
Select the proper attenuation ratio of the measuring instrument based on
