Dynamic Load Testing / Pile Monitoring (PDA)

Can PAX sensors be used with a PDA-8G unit? What additional equipment is needed? What are the associated disadvantages?
What is the maximum diameter of a pile on which we can perform a dynamic test with two sets of strain transducers?
I’m observing that the forces are of different magnitudes in a PDA test. Should I use the "Replay Factors" to adjust the data?
I need to order sensors from PDI, and am being asked if my connection is threaded or twistlock. How can I tell?
Why does the “DFN” value sometimes not match the actual set measured on site?
What is the hole pattern for PDA sensor attachment?
How can I check the calibration of the Pile Driving Analyzer® (PDA)?
Is a PDA test required during the test pile period to establish driving criteria, as well as during the production pile period?
How many PDA-8G tests are typically required in the USA?
Can uplift be estimated from dynamic testing?
How is the pile weight accounted for in dynamic testing?
