How to do a Gap Study

When you are ready to begin a Gap study, select Count from the Main

Menu, then select New and then select GAP.

You are then prompted to select a site code type and assign a site code.

Refer to page 2-5 for information on selecting a site code.

Interval

Once you have selected the site code you’ll be prompted to select an

interval length.

You are given the choice of 1, 5, 15, 30, or 60 minute intervals. An In-

terval is the amount of time the TDC Ultra collects data before it stores

the accumulated totals in memory. You are barely aware of intervals

changing when you do a study with the TDC Ultra (it beeps at the end

of each interval to let you know it may be time to go home). The TDC

Ultra automatically keeps track of the time and stores the data at the

end of the interval. You only have to concentrate on collecting the data.

This is one of the major features of the TDC Ultra.

The most common intervals for Gap studies are 5 and 15. We rec-

ommend that you use these unless you have special requirements.

Press DO once you have selected the interval length you wish to use.

Start Study

After you have selected an

interval to use, you are ready

to start the study. The display

shows the current count num-

ber and the interval number. In

the example shown, this is the

ﬁrst count done, and it is at the ﬁrst interval.
