It is not necessary to unlock the counter to perform Auto-Cal. However, any
signals routed to the Channel input connectors should be turned off or
disconnected. Also, see the CAUTION below.
A successful ACAL will result in the automatic update of the compensation
factors that a previous ACAL has measured and stored. Since ACAL changes
these compensation factors, if there is a case where the user is making a
measurement (or a series of sequential measurements) and doesn’t want
these compensation factors changed, the user may not want to run ACAL or
Self Test.
See Figure 2-3 for a summary of the front panel calibration procedures.
