Once familiar with the calibration series of setups, the calibration time may be sped up by
using the command "CAL OFF". This command allows the instrument to automatically
go to the next logical step in the series. The last column in Table 3-18 identifies which
steps in the series can be run automatically. For example, all of the Open steps can be run
by entering:
Another example is automatically running the ACV zeros from step 3 through step 12 in
Table 3-18 with:
Using the CAL? command without an argument turns off the single step
feature.
AC linearity steps must be run with AC Gain steps to complete the AC
calibration.
