Technical features for HPT testing:
1. HPT used for determine the pile bearing capacity and pile integrity.
2. It can be used for pile driving monitoring and the cast-in-place pile testing.
3. Sampling frequency is optional of 10 kHz, 20 kHz, 30 kHz and 40 kHz.
4. Sampling points are optional of 1024, 2048 and 4096. Maximum sampling time is up to 400 ms
5. Before testing, the two accelerometers and two strain transducers are self-checked automatically, determine whether the system is in normal state.
6. Automatically check the static strain deviation of the strain transducer during installation and adjust to zero before blow.
7. Test data exported through the external u-disk
8. During test every blow can be saved automatically
9. Storage capacity of more than ten thousands blows.
10. HPT data can save as *.X01 (used for PDA-W)
11. The main cable and connecting cable are compatible with the PDA.
12. Built-in lithium battery can be used more than 6 hours continuously.
13. PDAR program is for CASE method analysis.
14. RCAPWAP program is for match analysis automatically.
Technical features for LPT testing:
1. With the imported accelerometer from America with the high precision
2. 24bit high precision AD resolution
3. Sampling frequency 48kHz,96kHz,144kHz
4. Sampling points 4096
5. For the field data collection, it has average function for multi blows
6. It has auto statistical function for test piles quantity
7. The data can be exported by U disk
8. It has small wave analysis function
9. It can save the data by auto or manual method
10. It can do analysis for index amplification and small wave during testing
11. Built-in lithium battery can be used more than 6 hours continuously.
