When the setpoint reaches the specified Stop temperature, the next pulse will
reset the setpoint back to the Start temperature. The setpoint cannot exceed the
Stop temperature, and any attempt to step beyond the Stop temperature will
instead reset the setpoint back to the Start temperature.
Trigger Out
The sixth page of the system menu allows the user to set up the trigger out delay
time..
The Trigger Out feature allows the user to determine if the instrument is
controlling a TEC within a specific tolerance window. This window is defined by
the setpoint +/- a user specified tolerance. (See the Limits portion of the
Parameter Section later in this chapter for details on how to set this tolerance
value.) If the measurement for the selected control mode (e.g. Temperature) is
within this tolerance window, the Trigger Out TTL level will be high, if out of
tolerance, the level will be low. The Trigger Out signal is output from the TRIG
OUT BNC connector. (See the Rear Panel Overview section earlier in this chapter
for connector location.
The delay time determines how long the measurement must remain within the
tolerance window before Trigger Out is asserted high. If the measurement goes
out of tolerance during this delay period, the delay time interval is restarted when
the measurement goes back into tolerance.
