Hysteresis
The respective limit value output only switches after the first, second
or third bad analysis (suppression of the first or the second measured
value). This increases the reliability of the analysis evaluation, e.g.
after the measuring point has been switched over or if the sampling
line has not been flushed sufficiently. The hystereses of the two
outputs LV1 and LV2 can be set independently of each other.
With a hysteresis of "2", the next analysis is immediately carried out
when the limit value of this analysis has been exceeded for the first
time. The respective output is only switched after the limit value of
this analysis has been exceeded for a second time. With a hysteresis
of "3", the respective output only switches when the limit value of this
analysis has been exceeded for a third time. This setting is only
reactivated once the value has fallen below the limit value!
(The basic setting for LV1 and LV2 is 1)

Lock out
Analysis monitoring with locking after the first, second or third time a
limit value is exceeded (= hysteresis) is used for
error diagnosis . If a
limit value (programmable: LV1 or LV2) is exceeded as often as
programmed (limit value output switched), the instrument remains in
the analysis position and switches to standby (indicator lamp
"STANDBY" illuminates). In the LOCKING position (display
"STANDBY"), the sample remains in the measuring chamber. This
ensures that the analysis result can be visually checked for faults
caused by external effects (e.g. when measuring the water hardness,
excessive iron or copper content results in brown colouration).
Locking is cancelled via the "STANDBY" key.
