A lower value averages fewer elevation measurements, allowing the system to react more quickly to smaller
grade changes. This makes the system more susceptible to fluctuations in temperature or small obstructions.
A larger value averages more elevation measurements, preventing the system from reacting to undesirable
items close to the reference. This also makes the system less susceptible to fluctuations in temperature or small
• Averaging value range – 1 to 100
• Factory preset – 50
Figure 58: Averaging
Elevation Deadband is the area of the Working Window that is On-Grade. While the reference is within that area,
the paver’s valves are idle (closed). Therefore the wider the Elevation Deadband (On-Grade area), the more a
reference can move up or down without a correction being initiated. Once the signal from the reference is out
of the deadband, your Topcon P-32+ or P-32 System drives the hydraulics to place the reference back in the
center of the deadband.
• Elevation Deadband value range – 1 mm to 30 mm
• Factory preset – 3 mm (0.01 ft or 1/8 in)
Figure 59: Elevation Deadband
Select the amount of Elevation Deadband carefully. Too small of an Elevation Deadband causes the
tow point cylinder to constantly hunt up and down while the sensor tries to find On-Grade. Too large
of an Elevation Deadband does not allow the sensor to send grade corrections to the values, causing
unwanted variations in mat thickness.
