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]
・ Calorific value [*CALRY]
Press the [YES] key to enter the desired mode when it is indicated.
(b) Set the upper/lower limits.
・ Physical density [*L_DNS], [*H_DNS]
Configure range:
00.0000 to 60.0000 (kg/m
3
),
0.00000 to 4.00000 (lb/ft
3
)
・ Compensated density [*L_CP.D], [*H_CP.D]
Configure range:
0.0000 to 6.0000 (kg/m
3
),
0.00000 to 0.40000 (lb/ft
