Description
Zoom Zooms in the current curves with a specified scale
Zooms out the current curves with a specified scale
Restores curves in the chart
File operation Opens an existing .trc file for curve display in the chart
Saves the current recording of values in the following file formats:
• .trc: trace curve files
• .png: time domain charts or frequency domain charts
Reset scaling Displays the selected curves with the same scale, that is, the biggest scale of all
selected curves
Note:
In frequency domain chart, horizontal cursor button
is unavailable.
④
Chart
• Time domain chart:
Displays the time chart in curves and records measured values of parameters
• Frequency domain chart:
Available for mathematically computed curves and displays the Fourier trans-
formation
• Bode diagram:
Available for mathematically computed curves
⑤
Time domain chart
T Coordinate T (time):
• t1: Real-time value of coordinate t1
• t2: Real-time value of coordinate t2
• dt: Automatically calculated duration
Formula: dt = t2 - t1
Y Coordinate Y:
• y1: Real-time value of coordinate y1
• y2: Real-time value of coordinate y2
• dy: Automatically calculated value range
Formula: dy = y2 - y1
Y(T)
• y(t1): real-time value at the cross point of coordinate t1 and selected curve
• y(t2): real-time value at the cross point of coordinate t2 and selected curve
• dy(t): automatically calculated real-time value range
Formula: dy(t) = y(t2) - y(t1)
Note:
You can select a coordinate by clicking its designation, then the selected coordinate is displayed yellow.
