43.2 Menu >Alert< / >Level<
Fig. 43-2 Level
The >Level< subsection permits to specify up to five different limit values by using the “+” and
“-” keys in
>Upper threshold Entries< and in >Lower threshold Entries< each of which is
used to trigger an alarm e-mail.
Define the threshold values by clicking the fields and by entering numerical values. The
measurement transmitter will sort the specified threshold values in decreasing order. This is
made independent from the input sequence.
In >Hysteresis (abs.)< and >Hysteresis (rel.)< values can be specified by clicking and typ-
ing. The measurement transmitter evaluates both values and sends an e-mail on reaching
the highest top limit (highest possible value) and the lowest bottom value (lowest possible
value). This mail includes the information that the alert is cancelled.
Default settings:
Hysteresis (abs.): values and units depend on the language settings previously adjusted
Hysteresis (rel.): 5,0 %
Moreover, the >Alert on error< option can be checked causing an active ongoing alert to
send an alarm e-mail. Possible errors are cable breaks, interruptions, short circuits etc.
