Trigger delay. Setting a positive value delays the effect of the trigger
event until the set time has elapsed. Entering negative values allows
pretriggering (limited to a few ms, depending on the sensor).
The trigger delay is set in an editing field with direct entry of values
(see Chapter 3,
Dialog boxes and their controls
).
Tip
Entering a correct value for the trigger delay is absolutely essential for
accurate measurements in the Timeslot mode. For this reason, the
setting should always be checked in the Scope mode
(
T’slots,
p. 4.45).
