Turn the M knob to set the Amps/Volts ratio. The
range is 100mA/V ~ 1KA/V.

1. 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 MENU button to show CH1 SETUP menu.
(2) Press the H1 button, the Coupling menu will display at the screen.
(3) Press the F1 button to select the Coupling item as "DC". Both DC and AC
components of the signal are passed. The waveforms are shown as Figure
5-2.
(4) Then, press F2 button to select the Coupling item as "AC". The direct current
component of the signal is blocked. The waveforms are shown as Figure 5-3.
