Preparations for PCS900 Measure-up
Park the paver on a level surface
Ensure the screed is level/flat (ask for assistance if unsure)
If the paver has “Rear Extensions”, set the paver to the paving width
Ask contractor what the typical paving widths will be for the 3D Paving Project
Complete a Measure-up for every width at 1.5’ intervals on each side
E.g.: 12’, 15’, 18’, etc…
If the paver has “Front Extensions”, measure to the Main Screed which is the Trailing Edge
Lower the screed on starter blocks
Move the paver forward to remove any tow arm slack
Zero tow arms
Null screed (e.g.: using screed cranks)
Set screed at normal angle of attack

4. Trimble PCS900 Measure-ups using SPS930 UTS
We have to take 7 measurements on the paver
Using SPS930 & SCS900
1  MT900 – Left (MTL)
2  Outside Tow Arm Left (TAL)
3  Screed Tip Left (STL)
If Dual Masts are installed (highly recommended)
4  MT900 – Right (MTR)
5  Outside Tow Arm Right (TAR)
6  Screed Tip Left (STL)
Using Steel Tape
7  Screed Trailing Edge to Tow Point Cylinder Center

6. Trimble PCS900 Measure-ups using SPS930 UTS
Setting up the SPS930
Prior to setup, ensure the SPS930 can see both sides
If you do not have 4 reflective targets, have a person hold the reflective target on the Tow Arms and Screed Tips
Have a person stand behind the paver and in line with the center of the screed until they can see all points
This is where the SPS930 needs to be setup

8. Trimble PCS900 Measure-ups using SPS930 UTS
Setup the SPS930 Using SCS900
Create a New Site and Work Order
E.g.: PCS900 Measure up DATE
Add two Control Points
First: , 5000, 100
Second: 5200, 5000 (uncheck Elevation)
Set Up Instrument Position
Setup on a known control point
Select Instrument Point (Control1)
Select Reference Point (Control2 which is to the North or top)
Aim towards the center of the paver
CHECK ON “Shooting angle only”
Select “Measure” and Complete Instrument Setup
Select: “Measure control points”

9. Trimble PCS900 Measure-ups using SPS930 UTS
Before measuring with SCS900, you must set the Target Height = 0 (zero)
You will also need to change the Target Types between Measurements!
1  MT900  Left = RMT ID 9
Check ID to ensure the MT900 is connected!
Lock the SPS930 onto the MT900 Left
2 & 3  Acrylic Target (TAL & STL)
4  MT900  Right = RMT ID 10
Lock the SPS930 onto the MT900 Right
5 & 6  Acrylic Target (TAR & STR)
PLEASE NOTE I: You will need to move and connect the MT900 Target prior to measuring the opposite side (i.e.: 4 )
PLEASE NOTE II: Do not use the DR or Autolock (to the Acrylic target) functions to measure the points.

11. Trimble PCS900 Measure-ups using SPS930 UTS
Depending on the MT900 locations vs the Screed Tips, SCS900 should look like this after the measurements are complete:
4 
1 
2 
5 
3 
6 

12. Trimble PCS900 Measure-ups using SPS930 UTS
7  Using the Steel Tape, measure the Screed Trailing Edge to Tow Point Cylinder Center

13. Trimble PCS900 Measure-ups using SPS930 UTS
Measuring Masts Leans
Use a Calibrated SmartLevel or SmartTool
Measure and Record the Mast Lean In or Out from Screed Tip
Place the level against the mast and parallel to the screed trailing edge
Determine the Mast Lean in degrees from Vertical (90o)
Measure the Mast Lean In or Out from Screed Tip
If the mast leans out from the paver, the value is negative (-)
If the mast leans in from the paver, the value is positive

Measuring Masts Leans

15. Trimble PCS900 Measure-ups using SPS930 UTS
Measuring Masts Leans
Use a Calibrated SmartLevel or SmartTool
Measure and Record the Mast Lean Back or Forward from Screed Tip
Place the level against the mast and parallel to the screed trailing edge
Determine the Mast Lean in degrees from Vertical (90o)
Measure the Mast Lean Back or Forward from Screed Tip
If the mast leans forward towards the front, the value is negative (-)
If the mast leans back towards the screed, the value is positive

16. Trimble PCS900 Measure-ups using SPS930 UTS
In SCS900, go to
Volume & COGO > Compute Distance & Area
Use the PCS900 Measure-up Excel Spreadsheet to complete the key-in measurement information

Computed PCS900 Entries (2nd Tab)

19. Trimble PCS900 Measure-ups using SPS930 UTS
Turn on the PCS900 display in Manager Mode
Go to the Installation Menu
Select Machine Settings > Edit Machine
Key-in a Machine name (e.g.: make, model and perhaps machine number)
Follow the instructions carefully and select the appropriate settings

20. Trimble PCS900 Measure-ups using SPS930 UTS
Machine Settings Example:

21. Trimble PCS900 Measure-ups using SPS930 UTS
In the Installation Menu
Select Machine Dimensions > Mast Measurements
Read all Instructions carefully and proceed to the “Mast Measurements”
PLEASE NOTE III: Change “Measure Method” (F3) to “Center of UTS target”

22. Trimble PCS900 Measure-ups using SPS930 UTSF1 F2 F3 F4 F5 F6

23. Trimble PCS900 Measure-ups using SPS930 UTS
Using the “PCS900 Entries” from the excel spreadsheet, key-in the computed values for both the Left and Right sides
Include the Masts Leans and Trailing edge to tow point cylinder values
PLEASE NOTE IV: When using “Center of UTS target”, YOU MUST set the “Height of the starting block” = for both the LEFT and RIGHT sides!!!
The mast height dimensions are being calculated to the screed tips (top of the starting blocks) and not to the ground

24. Trimble PCS900 Measure-ups using SPS930 UTS

25. Trimble PCS900 Measure-ups using SPS930 UTS
When all the mast measurements are keyed-in, go to “Machine Body”
Machine Dimensions menu
Key-in the “tow arm width” and the “Trailing edge to tow point cylinder” dimensions
Go to Installation > Calibrate Sensors
Calibrate both the Left and Right side AS450’s using the Mast Lean values (back/forward; in/out)

26. Trimble PCS900 Measure-ups using SPS930 UTS
PCS900 only saves one “persist” machine file which includes all the dimensions, etc… and “Text Items”
Prior to saving the persist file, set the Text Items

27. Trimble PCS900 Measure-ups using SPS930 UTS
Sample PCS900 Test Items

28. Trimble PCS900 Measure-ups using SPS930 UTS
Go to “Save Settings” and include the screed width and date

29. Trimble PCS900 Measure-ups using SPS930 UTS
If the paving contractor will be paving variable widths with a rear mounted screed
Raise the screed and set the width
Proceed in setting up the machine/screed prior to measure-up and repeat the measure-up process
Save the Machine with the new width and include the date
Please Note V: You do not need to re-impute the Text Items
