4.0 WORKING WITH TEST RECORDS
The TTRA software can be used to retrieve test records from the ATRT or from the PC hard
drive. Once a test record is retrieved, you can change the record header settings, print the test
results, change the H Voltage, X Voltage, H Tap, and X Tap values, and save the record to the
hard drive.
NOTE
If the H Voltage and/or X Voltage values are changed, the TTRA software will
automatically re-calculate the calculated ratio and deviation. Make sure to save
the test record after making any changes. See section 4.3 for information on
