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 is shown as follows:
(1) Press the CH1 MENU button to show CH1 SETUP menu.
(2) Press the H3 menu selection, the Probe menu will display at the right of the
screen, then press the F2 button to select X10 for the probe.
The Fig.5-3 illustrates the setting and the vertical scale factor when the probe of
the attenuation coefficient of 10:1 is used.
Fig. 5-3 Regulation of the Attenuation Ratio of the Probe
A list of the probe attenuation coefficient and the corresponding menu settings:
Attenuation Coefficient of the Probe Corresponding Menu Setting
1:1 X1
10:1 X10
100:1 X100
1000:1 X1000
3. 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 MENU button to show the CH1 SETUP menu.
(2) Press the H2 menu selection button and select ON for Inverted item. The
waveform is inverted as it is shown in Fig.5-5.
(3) Press the H2 menu selection button again and select OFF for Inverted item.
