Level and time used to judge whether alarm
conditions are met (level/time)
• For the module
When the data refresh interval or recording
interval is longer than the value set in Box 8,
the data refresh interval or recording interval,
whichever is longer, will be set.
• For the pulse or waveform calculation
When the recording interval is longer than
the value set in Box 8, the time is set to the
recording interval.
In both cases, the level is calculated as
follows:
(Level) = (Value set in Box 7)
× {(Time) / (Value set in Box 8)}.
