Model 520 HT UCA

 

D01157216 

Revision A, October 2015

2.

 

Apply compressed air pressure of 60-180 psi to the cell. 

3.

 

Insert the cell into the instrument and connect the top transducer and 
thermocouple cables. 

 

 

4.

 

In Instrument Setup, select CALIBRATE TRANSIT TIME from the touch 
screen menu.  When the calibration screen appears, press the CALIBRATE 
button.  If the waveform appears acceptable, press DONE to save the new 
calibration values.  In general, the peak amplitude should be 600 or greater 
with water.  If an acceptable waveform is not displayed, check the 
transducers and cables and recalibrate. 

Transit time calibration is different from older UCAs.  The steel calibration bar is 
no longer required.  The unit is now calibrated with water.  It is imperative that 
there be no air in the water during calibration or while a test is in progress.  

Incorrect or improper calibration values are the most likely reason for the UCA to 
report incorrect strength values.  The calibration should be checked whenever the 
transducers are removed or if the compressive strength values become suspect.
