Use Mathematical Manipulation Function - Owon SDS1000 User Manual

below:
(1) Push the CH1 button to show the CH1 SETUP menu.
(2) In the right menu, select Coupling as DC. Both DC and AC
components of the signal are passed.
(3) In the right menu, select Coupling as AC. The direct current
component of the signal is blocked.
2. 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) Push the CH1 button to show the CH1 SETUP menu.
(2) In the right menu, select Inverted as ON, the waveform is inverted.
Push again to switch to OFF, the waveform goes back to its original
one.
3. 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 Coefficient" on P11). If the
attenuation coefficient of the probe is 1:1, the menu setting of the input
channel should be set to1X.
Take the Channel 1 as an example, the attenuation coefficient of the probe
is 10:1, the operation steps are shown as follows:
(1) Push the CH1 button to show the CH1 SETUP menu.
(2) In the right menu, select Probe. In the left menu, turn the M knob to set
it as 10X.
4. To measure current by probing the voltage drop across a resistor
Take the Channel 1 as an example, if you are measuring current by
probing the voltage drop across a 1Ω resistor, the operation steps are
shown as follows:
(1) Push the CH1 button to show CH1 SETUP menu.
(2) In the right menu, set MeasCurr as "10.0V/A / 100.0mV/A", select the
10.0 A/V radio menu. Turn the M knob to set the Amps/Volts ratio.
Amps/Volts ratio = 1/Resistor value. Here the A/V radio should be set
to 1.
