Instruction manual

To adjust using Centurion software select either Test Sensors or Monitor Lanes and select the Set Piezo Button. The

display will show the following:

These are the default settings:

GAIN feature, key in #1 key. Gain has a range of 1-8

THRESHOLD press the #2 key; range is 5-255

TIME press the #3 key; range is 5-10K

PERCENTAGE press #4 key; range is 5-95%

When you have the desired feature displayed on the screen, key in the new desired number value. The TIME

value is a dead time during which circuitry will not accept input from a sensor after the last axle has left the sensor.

This helps to eliminate ghost signals. If ghosting is a problem, enter value up to 40 for traffic speeds of 60 mph, 25-

30 for traffic speeds of 70-80 mph (default is 30).

4.g. Time of Shutdown

Time of Shutdown will give the last shutdown time of the system. Press the number ”5” from the menu and the display

will show:

Press ENTER to see the time of shutdown

The last time and date of shutdown are displayed. Note the date will be

displayed in the format selected in the configure system option.

Note that the time of shutdown is either the time the power was shut off on the counter or the time the counter shut itself

off due to a weak battery. It is NOT the time the counter stopped collecting data.

4.h. Configure System

Configure System will give the last shutdown time of the system. Press the number “5” from the main menu and the

display will show:

Press ENTER to begin system configuration.

This asks which storage mode you require. The choices are Raw, Binned,

Count or Sensor.

This asks which format you require for the date. Options are: MM/DD/YY, DD-

MM-YY, and YY-MM-DD.

You must have the following software version in your computer to access these features: Centurion 1.28
