5.6 Setting the Probe Attenuation
Procedure
1.
Press one of the
CH1
to
CH4
keys to select the channel.
2.
Press the
Probe
soft key.
3.
Press the soft key corresponding to the desired type (attenuation ratio).
Set the attenuation
using the rotary knob.
Explanation
The following probe types can be selected for each channel:
AUTO, 1 : 1, 10 : 1, 100 : 1, 1000 : 1, 10 A : 1 V, 100 A : 1 V.
• 1 : 1 to 1000 : 1 are probe attenuation settings.
• 10 A : 1 V and 100 A : 1 V are probe output current rates.
• If AUTO is selected then the attenuation is automatically selected when the probe is
connected to the corresponding probe interface.
In addition to using the soft keys, you can now select the probe attenuation using the
rotary knob. When using the rotary knob, you can select from the choices below. The
menu corresponding to the attenuation that you select with the rotary knob is highlighted.
Auto, 1:1, 2:1, 5:1, 10:1, 20:1, 50:1, 100:1, 200:1, 500:1, 1000:1, 1A : 1V,10A:1V, or 100A:1V
Note
If the probe type is not set correctly, the voltage and scale values of the input signals will not be
displayed correctly. For example, if you set the attenuation to 1 : 1 when you are using a 10 : 1
voltage probe, the automatically determined waveform amplitude will be displayed as 1/10th the
actual value.
