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.
3.Junior User Guidebook
The set values of the probe switch are 1X and 10X (see
Figure 3-9
).
Figure 3-9 Attenuation Switch
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
