Alarm Tab
In the Alarms tab (
Figure 14 on page 26
), you specify ACMI alarm settings. To
return to the factory default alarm settings, click on the Factory Default button.
After you have set the alarm preferences, click the Apply Changes button to
record your settings in memory.
You can select or deselect the following alarm conditions:
Latch Alarms —
Sets whether the alarm will reset automatically in the
absence of an alarm condition. When this checkbox is unchecked, if an alarm
trigger is corrected, the VSWR alarm will reset after a forty-five second delay
and the power alarms after a one and a half second delay. When the box is
checked, the alarms must be manually reset.
Alarm at Power (Pwr) Up —
At power up, before the instrument is ready to
take measurements, the unit performs initialization tasks. During this period,
the unit’s alarm indicators (LED & TTL output) will activate for ~2ms and the
alarm relays will toggle to the alarm-active state for ~2ms (i.e. change from
activated to deactivated or visa-versa depending on the Relay Energized on
Alarm configuration).
Checking the Alarm at Pwr Up box will cause the unit’s alarm indicators and
alarm relays to remain in an alarm condition from the time power is applied
until the unit begins making measurements. At that time, the relays and
indicators will return to their no-alarm condition until an event activates them.
