Data logger view
Press Data Logger to access the data logger.
Items Description
1 Trace controls Identifies the voltage or current trace that will be displayed. √ indicates the trace is on. Dashes (----) indic-
ate the trace is off. Select the trace and press [Enter] to turn it on or off.
2 Data bar The data bar represents all of the logged data. The yellow part indicates the portion of the data that is vis-
ible on the display. The black part represents the data that is not visible.
3 Time/Div Identifies the horizontal time-base setting. This can be adjusted using the Horizontal knob after pressing
Knob Sc.
4 Offset time Indicates the time that the right gridline is offset or away from the end of the data log. When this value is
zero, it means that the right gridline is positioned at the end of the data log. Adjusting the offset will move
the grid away from the end of the data log, as indicated by the Offset Time. The offset can be adjusted using
the Horizontal knob after pressing Knob Ofs.
5 Trigger source Indicates the trigger source for the data logger.
6 Time elapsed Indicates the time elapsed during the data log and the total duration. The values match when data logging
finishes.
7 Filename Indicates the filename of the data that is being logged.
8 Ground reference The ground reference of the trace. Ground references are offset so that they do not overlap. The ground ref-
erence offset value is referenced to the horizontal center line of the grid.
9 Data traces Voltage trace labels appear on the left side of the grid (V1 and V2) as shown in the display.
Current trace labels appear on the right side of the grid (I1 and I2).
Power trace labels appear on the center of the grid (P1 and P2).
Press Auto Scale to auto-scale the data traces.
10 Grid time Displays the time on the gridline.
11 Out of view arrows Indicate that the trace, V2 in the figure, is out of view. Press Knob Sc or Knob Ofs and use the Vertical
knob to bring the trace into view. Press Auto Scale to autoscale the data traces.
12 Trigger point indicator Indicates the trigger position in the data log. In this example the trigger point was offset by 0%, and the pre
trigger and post trigger data was logged. The time at the trigger point is always zero. Change the trigger
offset in the Data Logger Logging Settings.
