To disable the parameters ("OFF"), press the key four times (see figure
below).
To pause the oscilloscope or scan function, select the "TAB" switch.
To adjust the measurement lines for voltage or current, select the
"Move" switch.
To select parameter "V-Move" (voltage), press the key once.
To select parameter "H-Move" (current), press the key twice.
To select parameter "VH" (voltage and current at the same time), press
the key three times.
To disable parameter "OFF-Move", press the key four times.
Top section of the display: selection of the measurement line for
voltage that can be shifted up or down. To adjust it, use the control knob.
Bottom section of the display: selection of the measurement line for
current that can be shifted up or down. To adjust it, use the control knob.
Left display section: select a left-hand time axis that can be shifted left
or right. To adjust it, use the control knob.
Right display section: select a right-hand time axis that can be shifted
left or right. To adjust it, use the control knob.
In order to adjust the amplitude of the oscilloscope voltage, select the
"V SET" key. Using the control knob, adjust the parameter by increasing
or decreasing it accordingly.
In order to adjust the amplitude of the oscilloscope current, select the
"I SET" key. Using the control knob, adjust the parameter by increasing or
decreasing it accordingly.
In order to adjust the path of the oscilloscope function curve over
time for voltage, select the "OVP" key. Using the control knob, adjust the
parameter by increasing or decreasing it accordingly.
After increasing the oscillogram, adjust the waveform for current (I).
Select the "OCP" key. Move the curve using the knob.
