Example 20TK100 | Pre-launch the acquisition of a series of 100 measurements.
The trigger signal is an external logical signal, that must be connected to
the TRIG input located on the rear panel of the LDS1000 Controller.

1 at NBMAX. Number of measurements to be performed
(NBMAX = Max. number of measurements related to the memo-
ry installed).
Possible error
nn outside authorized interval
1 to nn. Number of the measurement synchronized on trigger
pulse (TRIGG input).
Possible error
nn outside authorized interval
Performs an acquisition of nn measurements, as the measu-
rement xx is synchronous with the trigger signal (the acquisi-
tions are stored in a revolving memory of xx values while awai-
ting trigger signal).
The acquisition period is given by SP.
The integration constant set by KI is used.
The number of the acquisition in progress is given by XN.
XN remains equal to zero while the trigger signal is absent,
then Xn directly takes the value xx.
If the trigger signal arrives before xx measurements are stored
in the memory, the first values will be set at MIN, MIN being
the lowest limit of the measurement range of the sensor used.
None.
Parameter out of limit.
Execution not allowed.
Variable is out off range.
Measurements 1 to 19 precede the trigger signal, measurement 20
is synchronous with this signal and measurements 21 to 100
come after it.

Error C.
Error O.
