Chapter 5 Operating Functions
You can select up to eight basic measurement parameters and display fluctuations in their respective
measured values as a graph. The generated screens can be saved as screenshots.
Press and key to display the [Trend] page.
Graphed parameters
The graph number, graphed parameter, and scale setting are shown.
[SEMI AUTO] is shown if a scale factor has been set, while [AUTO] or
[MANUAL] is shown if using the AUTO or MANUAL setting, respectively.

play method
The displayed graph waveforms are generated by graphing virtual D/A output wave-
forms on the screen. Consequently, some combinations of display parameters may
result in unusually shaped graphs based on the D/A output rules.
• D/A output rules
See: "8.3.3 Output Level" (p.169), "8.3.4 D/A Output Examples" (p.170)
• Integration scale and frequency full scale settings
See: "8.3.2 Output Item Selection" (p.166)
On the Trend screen, measured values that fall outside the display range (see "10.5 Mea-
surement Item Details" (p.207)) are clipped in principle to the maximum display value.
This functionality applies to the following displays:
• Graph waveforms
• Icons that indicate present measured values
To save fluctuations in measured values, use the auto-saving function (p.141) together.
