Note)
"Normal" refers to the volumetric flow rate (CFH) after converting to 32˚F,
1 atmosphere.
Handling Precautions
*1 Be certain to set a flow rate that is less than the display upper limit.
Alarm detection will not operate if flow rate is set above the display
upper limit.
*2 If "lower limit alarm1" has been selected in function setup
C-
, alarm
detection will not operate when the flow rate is less than the lower limit
of the measurement range, even if the flow rate is below the lower limit
alarm value.
