Upper limit value :
Sets the upper limit value (concentration) of alarm by range.
Lower limit value :
Sets the lower limit value (concentration) of alarm by range.
Contact action :
(1) Upper limit value
Alarm contact operates only when the upper limit value is exceeded (1
point).
(2) Lower limit value
Alarm contact operates only when the measurement falls below the lower
limit value (1 point).
(3) Upper limit/Lower limit value
Alarm contact operates when measured value exceeds the upper limit
value, or it falls below the lower limit value (1 point).
(4) Upper limit value + Lower limit value
Aalarm contact operates when measured value exceeds the upper limit
value, or falls below the lower limit value (2 points).
(5) Two-step upper limit value
Alarm contact operates alarm only when measured value exceeds two
kinds of upper limit values.
(6) Two-step lower limit value
Alarm contact operates only when measured value falls below two kinds
of lower limit values.
ON/OFF: Alarm function becomes valid with ON, and invalid with OFF.
* The upper limit value cannot be set below the lower limit value, and the lower limit value cannot
beset above the upper limit value.
If you want to set the upper limit value below the lower limit value already stored in the memory,
decrease the lower limit value first, and then make the setting. In the case of lower limit value,
increase the upper limit value before making the setting.
Description of setting items
