3.2.8 Alarm set up
This allows an alarm threshold to be set, and the alarm type to be defined as absolute high or absolute low. The default
threshold setting is 0.000 and this can be edited using the up and down arrow keys and cursor as described in section
3.2 above.
Figure 3.2.8 shows the keystrokes necessary to set the threshold of Channel 2, alarm 1, and how to define it as abso-
lute low.
An alarm can be disabled only by setting its threshold outside the range of the input signal.
See also CREL (section 3.2.11) for details of how to use the relay associated with channel 1 alarm 1 as a global alarm
indicator and HySt (section 3.2.11) for how to set a hysteresis value for all alarms. (See glossary for a description of
hysteresis.)
