ENGLISH

do.L : down/low alarm set-point with latch function. The alarm func-

tions as per “do” and can be reset only manually when the F key

is pressed for at least 2 seconds during the measuring phase.

Lo.S : minimum set-point value, which is programmable within the

range: Lo (Hi) < Lo.S < Hi (Lo). This limit to the set-point’s amplitude is

very useful when the set-points are managed outside the programming

phase.

Hi.S : maximum set-point value, which is programmable within the

range: Lo.S < Hi.S < Hi (Lo). This limit to the set-point’s amplitude is very

useful when the set-points are managed outside the programming

phase.

SEt : value of the alarm set-point to be programmed within the

following range: Lo.S < SEt < Hi.S.

HYS : hysteresis value of the set-point. The hysteresis is a numerical

value included within the range: 0 < HYS < 3999 and represents the

difference between the value of the ON alarm status and the value of the

OFF alarm status. The hysteresis modifies the value of the OFF alarm

status not only with regards to the set alarm value, but also with regards to

the alarm type: the hysteresis value is summed to the set value if the alarm

type is “do” and subtracted from the set value if the alarm type is “uP”.

Example:

“do” alarm, “SEt”=2200 (value of the ON alarm status), hysteresis

“HYS”=12⇒ resulting OFF value (end of alarm status): 2212 (resulting

from 2200 +12).

“uP” alarm, “SEt”=2200 (value of the ON alarm status), hysteresis

“HYS”=12 ⇒ resulting OFF value (end of alarm status): 2188 (resulting

from 2200 - 12).
