How To Use The Probe Safely - Owon XDS3204E User Manual

select the proper value corresponding to the probe.
This setting will be valid all the time before it is changed again.
Caution:
The default attenuation coefficient of the probe on the instrument is preset to
10X.
Make sure that the set value of the attenuation switch in the probe is the
same as the menu selection of the probe attenuation coefficient in the
oscilloscope.
The set values of the probe switch are 1X and 10X (see Figure 3-9).
Caution:
When the attenuation switch is set to 1X, the probe will limit the bandwidth
of the oscilloscope in 5MHz. To use the full bandwidth of the oscilloscope,
the switch must be set to 10X.
Identify the Probe Attenuation Coefficient Automatically
The oscilloscope can identify the probe attenuation coefficient of the 100:1 (impedance
5K±20%) or 10:1 (impedance 10K±20%) probe with the identifying pin. When you
attach the probe, the oscilloscope set the attenuation automatically on the oscilloscope
vertical menu for the channel to match the probe.
For example, if you attach a 10:1 probe with the identifying pin, the screen will prompt
"The probe attenuation factor is X10", and set the attenuation to 10X automatically on the
oscilloscope vertical menu for the channel.

How to Use the Probe Safely

The safety guard ring around the probe body protects your finger against any electric
shock, shown as Figure 3-10.
