Using the Traffic Counter Tester II
The front panel of the TCTII has several key components that must be iden-
tified. The first of these is the power switch. The power switch is located
on the lower left corner of the front panel. Sliding this switch to the right
will turn the tester on, and sliding it to the left will turn the tester off. The
next components that must be identified are the two air hose nozzles on
the right side, labelled A and B. These are the output of the TCTII, and are
used to connect it to a counter. The third item is the LCD panel at the upper
left. This panel displays the current configuration of the TCTII, informa-
tion about the last vehicle to pass, as well as the current operating mode.
There are two push-button switches located at the bottom of the front panel.
These buttons, labeled TAB and DO, are used to step through each operating
mode, as well as to activate a mode. There are two LEDs located above the
switches, labelled A and B. These LEDs correspond to the output nozzles,
and give a visual indication of the air pulse. To the left of the LEDs is the
Output dial. This dial controls the intensity of the air pulses generated by
the TCTII.
