If you want to change the measurement conditions
During synchronized measurement sampling, settings such as the time base and
sampling rate cannot be changed.
If you need to change these settings, stop measurement by all of the connected
instruments before making the changes. After making the changes, select the
[SYNC Start… ] button again in the Ext Term Settings Screen on the master
instrument.
When power is restored after a power outage during synchronized mea-
surement
Select the [SYNC Start… ] button in the Ext Term Settings Screen on the master
instrument.
Synchronized measurement does not restart if you do not select the button. Mea-
surement restarts if the Auto-Resume function (⇒ p. 338) is on, but no synchro-
nization is conducted with the connected instruments.
