Change the Advanced Time Graph Settings (optional)
DataMate contains default time graph settings for each sensor. You can change the
"window" in which the collected data is graphed, and you can change the type of
triggering used in the experiment.
Follow the steps below to change advanced time graph settings:
If you press  ADVANCED on the Time Graph Settings
screen, the Advanced Time Graph Settings screen appears.
YMIN and YMAX refer to the "window" in which the
collected data is graphed. YMIN refers to the lower bound
of the graph, and YMAX refers to the upper bound of the
graph. The YMIN and YMAX values shown on the screen
are the default range of the sensor in channel 1. (This will vary depending on
the sensor being used. For example, for the Temperature sensor, the range is
.20 to 125.)
1.
To change the window range to be graphed,
press Á CHANGE GRAPH SETTINGS.
A list of the connected sensors appears.
2.
Press the number beside the sensor you want.
3.
To change the type of triggering, press  CHANGE
TRIGGERING.
In the example shown, there are two types of triggering:
♦
For option 1 or 2, the CBL 2™ will trigger the start of
data collection based on a change in the data being
collected. (This is called threshold triggering.)
♦
For option 3, MANUAL TRIGGER, the CBL 2 will start collecting data when the
START/STOP button is pressed.
♦
For option 4, NONE, no special triggering will be set.
4.
Press the number beside the type of triggering you want.
If you select NONE, the Advanced Time Graph Settings screen appears.
or
If you select MANUAL TRIGGER, the triggering option is changed and the
Advanced Time Graph Settings screen appears.
or
If you select threshold triggering, DataMate asks you to
choose the trigger type.
♦
INCREASING means that the values of the data being
collected (such as light intensity or temperature) will
be increasing.
