3. You can only Continue the last study performed. Previous studies
cannot be continued.
4. You can Continue a study any number of times as long as the
first three rules apply.
When selecting the Continue option, the TDC Ultra automatically selects
the same counting interval and site code you used for the previous count.
When the information is downloaded, the analysis software combines
the data from the two sessions into one count, and puts zeros in all of
the data points between the two counts. An option in the software lets
you print just the collected data, so that all of the zeros are not printed
on the report.
Status
Before starting a New study or Continuing a previous study, the Status
menu can be used to determine whether or not there is enough memory
in the TDC Ultra to conduct the next study.
The status screen (shown above) shows you information about the
memory in the counter. The most important number is on the third
line, the percentage of memory left. You want to make sure you have
enough memory to do your study before you bring the TDC Ultra out
to the field.
The Appendix contains a chart which details how much memory each
study uses. If you are not sure you have enough room, you should
download the data in the TDC Ultra to your computer for processing,
and then clear the memory to free up space.
The status information is always shown when you turn on the TDC
Ultra counter, but you can also re-display it from the Count menu if
you didn’t notice it the first time.
