8.2.4 Setting of Inverted Waveform
Inverted waveform: The displayed signal reverses 180 degrees relatively to the ground potential.
Press F4 to set Inverted as ON to start Invert; as OFF to close Invert.
8.3 Make the Math Function Menu Setting
The WAVE MATH functions in showing the result of adding, subtracting, multiplying or
dividing calculation on CH1 and CH2 channel waveforms. Also, the result of arithmetic operation
can be measured with grid or cursor. The amplitude of the calculated waveform can be adjusted
with CHM VOL, which is displayed in the scale factor form. The amplitude ranges from 0.001
through 10 and steps in the 1-2-5 form, that is, it can be expressed as 0.001X, 0.002X, 0.005X…
10X. The position of the calculated waveform can be adjusted up and down with the CHM ZERO
key used.

Setting Description
CH1-CH2 CH1 waveform minus CH2 waveform.
CH2-CH1 CH2 waveform minus CH1 waveform
CH1+CH2 Add CH1 waveform into CH2 waveform.
CH1*CH2 Multiply CH1 waveform and CH2 waveform.
CH1/CH2 Divide CH1 waveform by CH2 waveform
To perform the CH1+CH2 waveform calculation, do the following:
1. Press the MENU key and the function menu appears at the right of the screen.
2. Press the MENU ▲ or MENU ▼ key to select WAVE MATH and 5 options are displayed
at the bottom of the screen.
3. Press the F3 CH1+CH2 key and the obtained waveform M appears on the screen.
4. Press OPTION until left bottom display as
— CHMath Volts/Div
— CHM Zero
