CHECKPOINT
• When the Time Gate setting is Absolute Time, both the starting and ending times must
be specified. The following table describes the relationship between the absolute
starting and ending times.
(3) Action ........................ This parameter selects whether the specified operation will be triggered only once
or repeatedly.
Single : The specified operation is triggered once and then the trigger is disarmed.
Repeat : Until the STOP key is pressed, the specified operation is repeatedly
performed whenever its trigger condition is satisfied.
(4) Start Condition .......... The Start Condition parameters specify the trigger condition that must be met in
order to initiate measurement.
• Source .................... Selects the trigger type to be used for initiating measurement.
Off : When the Source setting is Off, no trigger is used. Instead, measurement
is initiated by pressing the Start key.
Internal : When the Source setting is Internal, after the Start key has been pressed,
measurement is initiated when the specified trigger condition is satisfied.
Manual : When the Source setting is Manual, press the Trigger key to satisfy the
trigger condition and initiate measurement.
• Combination ........... This parameter can only be set when the Source setting is Internal. It selects how a
trigger condition is satisfied and the target channel(s).
LEVEL OR : The start of measurement is triggered when one channel satisfies the
trigger condition.
