If the calculator fails to communicate with LabPro, this error message
appears. Check that LabPro has batteries or is powered by the AC adapter
and that the link cable is properly connected. This screen will appear until
the link problem is fixed.
This is the Main screen. The top half of the screen shows the current sensor
setup and data collection mode. The bottom half displays the menu options.
A low battery icon appears in the lower right hand corner if the LabPro
batteries require replacement.
The program will default to that sensor’s particular Time Graph settings. In
this example, you have a Temperature probe, reading in Celsius, and
collecting data as a function of time for 100 seconds. The Main screen
supports a meter mode displaying readings for active probes every few
seconds, as displayed in the upper right-hand corner. The meter option can
be toggled on and off by pressing
+ on the calculator.
DataMate will automatically identify auto-ID sensors, display the channel each is connected to
and the current reading. Only active channels will be displayed. The screen will update as new
auto-ID sensors are connected to the interface. Older sensors that do not have auto-ID need to be
manually set up. Photogates, graph matching, Rotary Motion sensors, and radiation monitors
require separate programs. These programs are described in the Supplemental Programs section.
You can reset the DataMate program by pressing the
CLEAR button on the calculator. This
reloads the calibration information onto the interface, but it also resets the DataMate program,
which resets the data collection parameters. It is important to press
CLEAR before setting up
DataMate for a new experiment. If you do not want to lose the data collection parameters use the
following method.
The second method only reloads the calibration and does not reset the DataMate program. To use
this method, simply press the
GRAPH button on the 73/82/83/84 or 86 calculator or the 0 button in
the 89/92 or Voyage 200 while on the main screen of DataMate.
If too much time has passed while on the Main screen or on other screens,
the message at right appears. If you do not respond, the calculator and
LabPro will shut down to conserve batteries. If you want to continue after
this happens, turn the calculator back on and select
YES . When you select
YES , the program resumes. If NO is selected, the program quits.
If you select the START option on the Main screen, LabPro will start
graphing your data.
Tip
: If at any time you wish to stop the data collection and view what has
been collected, press the
STO
key.
When the timed data collection is complete, an autoscaled graph of your
data is shown. Using the
and keys on the calculator, you can
move the cursor along the graph and get readings for the x and y axes.
