Enables the USP645 alarm set point value to be adjusted for increased process protection,
i.e. the USP alarm set point value in Table 5.3 is offset by the amount entered (table value
– offset value) to enable the alarm to be triggered early.
Note. The parameter is available only on AX450 and AX455 analyzers and only

Alarm 1 Set Point
Set the alarm set point to a value within the input range being displayed – see Table 5.2
(page 22).
Alarm 1 Hysteresis
A differential set point can be defined between 0 and 5% of the alarm set point value. Set
the required hysteresis in 0.1% increments.
See also Figs. 5.1 to 5.5 (page 33).
Alarm 1 Delay
If an alarm condition occurs, activation of the relays and LEDs can be delayed for a
specified time period. If the alarm clears within the period, the alarm is not activated.
Set the required delay, in the range 0 to 60 seconds in 1 second increments.
See also Figs. 5.1 to 5.5 (page 33).
Alarms 2 and 3 configuration (and Alarms 4 and 5 if option board fitted and

analog features enabled – see Section 7.3) is identical to Alarm 1.
