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.
Function: A further analysis is carried out immediately after the limit
value has been exceeded for a hysteresis of 2. The respective output
only reacts if the limit value of this analysis is exceeded again. If a
hysteresis of 3 has been set, the respective output only reacts after
the limit value has been exceeded for the third time in succession.
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 coloration).
Locking is cancelled via the "STANDBY" key.
