Frequently Asked Questions
Question:
How do I justify skidding a vehicle to determine drag factor?
Answer:
- Newton’s second law of motion says so.
- SAE Standard J2505 says so (June 2003).
- Drag sleds do not give the same number as the Vericom. The best you can expect with a drag sled is a number within 20% to 30%.
Question:
Can I prove the Vericom is accurate?
Answer:
Yes, by comparing the calculated speed of the Vericom with any known speed. The VC3000DAQ and the VC4000DAQ have appendage speed devices available.
Question:
Can I prove I used the Vericom correctly?
Answer:
Yes, by comparing the calculated speed of the Vericom with any known speed. The VC3000DAQ and the VC4000DAQ have appendage speed devices available. By confirming the speed you have proven the Vericom is accurate and you used it correctly.
Question:
Why is the Vericom better than other SAE recommended devices?
Answer:
The Vericom is the only device with Run Duration Protocol (RDP)™. This is an important part of the firmware program because RDP produces an objective calculated drag factor (f). All other devices produce a subjected f because the elapse time of the skid test is estimated by the user.
= Run duration protocol (RDP) ™
= Point of activation threshold
= Point of termination recognition
Question:
What are the advantages of Profile Professional software?
Answer:
Profile Professional software is a powerful graphic software that does tables, line graphs, analog meters, overlays and does calculations with range tables. It allows you to analysis, compare and store the data. Profile Professional software is designed for courtroom presentations. It is an essential requirement for comparing ABS to standard brakes and lateral G applications. Profile Professional software is included with the VC3000PC, VC3000DAQ and VC4000DAQ it is not licensed and may be installed on several computers at no extra cost.
