Before the probe zero is calculated the cal bars / glass block needs to be
ultrasonically measured. Once the zero value has been calculated, the results will
then need to be documented. This procedure is demonstrated in the next section.
Setting up the
MiniMax
for Measurement
Note:
Check to see if the system was previously calibrated. You should NOT
change the calibration unless the transducer, transducer cable, or instrument
has been changed. In any event, the probe zero calibration should always be
checked prior to changing it and only changed if it’s required. If the MiniMax
has been previously calibrated, open the calibration data saved in the MiniMax
and check the probe zero by simply measuring the bars in an empty location
(columns B – ZZ) in the existing probe zero data group. If the zero is off by a
value greater than .0005”, repeat the two point calibration section and
overwrite/record the values in column A of the calibration group for both the 3”
& 6” bars.
