Entering Skan/Measure Parameters (cont.)
1. The first prompt asks for the Percent of Peak, which is used to
calculate the transit times and Delta-T. The default value is 50,
and values from 1 to 100 are acceptable.
a. Press
[ENTER] to enter the text box.
b. Use the numeric keys to enter the recommended value.
c. Press
[ENTER] to confirm the entry.
2. The next prompt asks for Skan-T Offset, a time measurement
offset that compensates for any shift resulting from cross-
correlation. The default value is 12.6 µsec, and values from
-500 to 500 µsec are acceptable.
a. Press
[ENTER] to enter the text box.
b. Use the numeric keys to enter the recommended value.
c. Press
[ENTER] to confirm the entry.
3. The next prompt, M>S Switch, causes the meter to switch
from Skan to Measure Mode when Delta-T is less than the
M>S Switch value. The default value is 5.0 µsec and values
from 0 to 250 µsec are acceptable.
Note: Do not change this value without consulting GE
Panametrics. If you wish to use Skan only, set the M/S
Switch to a value of 0.
a. Press
[ENTER] to enter the text box.
b. Use the numeric keys to enter the recommended value.
c. Press
[ENTER] to confirm the entry.
4. The program now asks if you wish to Limit the Measurement
Delta. (The default is unchecked or off.)
a. Press
[ENTER] to enter the text box.
b. Use the numeric keys to enter the recommended value in
µsec.
c. Press
[ENTER] to confirm the entry.
