5. To set channel coupling
Taking the Channel 1 for example, the measured signal is a square
wave signal containing the direct current bias. The operation steps are
shown as below:
1. Press the CH1 button to show channel menu.
2. Select Coupling in the bottom menu.
3. Select DC in the right menu. Both DC and AC components of the
signal are passed.
4. Select AC in the right menu. The direct current component of the
signal is blocked.
6. To adjust the probe attenuation
For correct measurements, the attenuation coefficient settings in the
operating menu of the Channel should always match what is on the
probe (see "
How to Set the Probe Attenuation
attenuation coefficient of the probe is 1:1, the menu setting of the input
channel should be set to X1.
Take the Channel 1 as an example; the attenuation coefficient of the
probe is 10:1, the operation steps are shown as follows:
1. Press the CH1 button to show menu.
2. Select Probe in the bottom menu. Select ×10 in the right menu.

7. To invert a waveform
Waveform inverted: the displayed signal is turned 180 degrees against
the phase of the earth potential.
Taking the Channel 1 for example, the operation steps are shown as
follows:
1. Press the CH1 button to show channel menu.
2. Select ON for Inverted item. The waveform is inverted.
3. Select OFF for Inverted item. The waveform goes back to its
