Use the navigation keys and select the appropriate behavior for the TRIG OUT
signal. See Figure 25 for a detailed explanation.

Description
1 μs output pulse occurs at the
end of the signal acquisition (a/d
integration period), before the
reading is actually complete.
Push  (Polarity) to select a
Pos (high) or Neg (low ) pulse.
See Figure 25.
Square wave output with a high
or low level during the signal
acquisition (integrate) period.
Push  (Polarity) to select a
Pos (high) or Neg (low) level.
1 μs output pulse occurs after a
specified number of readings is
completed. Push 
(Polarity) to select a Pos (high)
or Neg (low ) pulse.
The number of readings is
determined by the Count
parameter in Trigger Setup. See
Triggering Measurements.
1 μs output pulse occurs when a
Limit is exceeded. Limits are set
in the Analyze function.
1 μs output pulse occurs after
each reading for any
measurement function. For ACV
and ACI, which are sampled
measurements, a pulse is output
after each computed reading, not
after each sample in the
measurement process. Push
 (Polarity) to select a Pos
(high) or Neg (low ) pulse.
Reference Multimeter and 8 ½ Digit Multimeter
Typical Usage
Trigger an external scanner
to the next channel. If the
scanner is a slower, relay
type, this setting advances
the channel sooner than the
Reading Complete event
below.
To minimize noise pickup
synchronizes external
equipment to only be active
when the Product A/D is not
acquiring a signal.
Synchronize an external
scanner to the Product when
making multiple readings
per scanner channel.
Advance an external
scanner to the next channel
when a voltage set by the
Limit Math function is
exceeded.
Synchronize an external
scanner to the Product when
making one reading per
scanner channel.
