15.1 Performing Addition, Subtraction,
Multiplication, and Division
This section explains the following settings for performing addition, subtraction, multiplication, and
division.
• Computation
Operator (+, –, *, /), computation source waveform, unit, label, turning the waveform display on and
off
• Scaling
Math waveform to scale (computed waveform), scaling mode, upper and lower limits of the display
range
• Computation start and end points
► Features Guide: “Basic Arithmetic (S1+S2, S1-S2, S1*S2, and S1/S2)”
“Scaling Mode (Scaling Mode)”
“Record Length (Record Length)”
MATH Menu
Press MATH to display the following menu.
Set the computation.
• Select the Math waveform (computed waveform) to scale (1-8).
• Set the upper and lower limits of the display range
(−9.9999E+30-9.9999E+30).
Set this when the scaling mode is Manual.
• Set the scaling mode (Auto, Manual).
Set the scaling.
Set the computation start and end points (−5div to 5div).
The setting resolution varies depending on the display record length.
The end point must be greater than or equal to the start point.
Note that there is a limitation in the number of data points that is used
depending on the number of equations to be computed.
Not all the data points may be used.
Set Mode to ON.
Configuring Computations (Math Setup)
1.
Press the Math Setup soft key.
2.
Press a soft key from Math1 to Math8 to display the following screen.
Select the operation (S1+S2, S1–S2, S1*S2, S1/S2).
Turns the waveform display on and off
Set the label.
Set the unit.
Select the computation source waveform
(U1-U4, I1-I4, P1-P4, AUX3-AUX8, Math1-Math7).
