Taking the Channel 1 for example, the operation steps are shown as below:

(1). Press the CH1 MENU button and call out the CH1 SETUP menu.

(2). Press the F3 menu selection button and select the Channel as OFF, with

Channel 1 switched off.

(3). Press F3 menu selection button again, select the channel as ON, with

Channel 1 is switched on.

Note: In FFT mode, both CH1 and CH2 are not allowed to be ON when F3 is

pressed. See Fig.5-4.

Fig. 5-4 Channel CH1 is disable under FFT mode

4. Regulate the Attenuation Ratio of the Probe

In order to match the attenuation coefficient of the probe, it is required to adjust
the attenuation ration coefficient of the probe through the operating menu of the
Channel accordingly. If the attenuation coefficient of the probe is 1:1, that of the
oscilloscope input channel should also be set to 1X to avoid any errors presented
in the displayed scale factor information and the measured data.

Take the Channel 1 as an example, the attenuation coefficient of the probe is 10:1,
the operation steps is shown as follows:

(1). Press the CH1 MENU button, access CH1 SETUP menu.

(2). Press the F4 menu selection button and select 10X for the probe.

The Fig.24 illustrates the setting and the vertical scale factor when the probe of
the attenuation coefficient of 10:1.is used.
