Description
Zooms in the current curves with a specified scale
Zooms out the current curves with a specified scale
Restores curves in the chart
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
•
Displays the selected curves with the same scale, that is, the biggest scale of all
selected curves
is unavailable.
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
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
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(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)
