When Alarm Continues
If abnormal measurement value status (alarm) occurs, the alarm is determined
when it occurs continuously for 10 sampling cycles. When the alarm is d e-
termined, the alarm indicator lights and the alarm output is ON.
If the alarm occurs less than 10 sampling cycles, the measurement value is
"+999.9999". The judgment result immediately befor e is held and the alarm
output is OFF.
