2. Alarm-point Setting Mode [*ALARM]
Set the upper /lower limits for the measured values of the parameters noted below, for the pur-
pose of raising an alarm.
(a) Select a parameter for which alarms are raised.
・ Physical density [*DENS]
・ Compensated density [*C_DNS]
・ Specific gravity [*SP_GR]
・ Calorific value [*CALRY]
