*Note that the 24-hour totals begin from when you start the count.
If you start the count at 3 pm on Monday, your first 24 hour totals
will be from 3 pm Monday to 3 pm Tuesday, etc.
Hourly option - if you Totalizer was configured to provide hourly
totals, you will see separate totals for each hour of the days you have

record 72 sepearte totals, one for each hour in 3 days.
DT
To access the DT menu, in the Setup Menu press the TAB key until DT
is flashing then press the DO key.
DT, which stands for Dead Time, is the amount of time the counter
will wait before it accepts new data. For normal traffic conditions and
speeds, the 30ms entry should be used. However, if you are counting
low speed traffic (below 15 mph) you should adjust the DT to either 90
or 320, depending on how slow the traffic is moving.
*Note that loop counters have a default DT setting of 320ms.
Other factors, such as tube length and placement will also affect the
accuracy of the data collection at low speed conditions. Generally, a
tube length of no longer than forty (40) feet should be used in low speed
conditions. Refer to Chapter 3 for more information on setting up your
road tubes properly.
Layout
*Note that this option is only available for two input counters.
To access the Layout menu, in the Setup Menu press the TAB key until
Layout is flashing then press the DO key.
There are three layouts available to choose from: L1 (A,B); L2 (A, B
minus A); and L3 (A to B, B to A).
