●Level judgement mode
The alarm is ON when display value exceeds
judgement value (over alarm)
The alarm is ON when display value underruns
judgement value (under alarm)
Over alarm (upper limit judgement)
Condition of comparison
Result
display value>AL1 judgement value AL1
display value>AL2 judgement value AL2
display value>AL3 judgement value AL3
display value>AL4 judgement value AL4
Under alarm (lower limit judgement)
Condition of comparison Result
AL1 judgement value>display value AL1
AL2 judgement value>display value AL2
AL3 judgement value>display value AL3
AL4 judgement value>display value AL4
●Zone judgement mode
The alarm is ON when display value between upper
and lower judgement values (inside of zone alarm)
