Alarm operation test
8-1-6.
This function is used to test alarm operations (Alarm1, Alarm2, and three-way valve output signals) in the manual or automatic running state.

under the concentration value measured in the running state.)
When the measured oil concentration exceeds the oil alarm points (Alarm1 and Alarm2),
an alarm state is set and the three-way valve output signal is OFF. AL1, and AL2 alarm
lamps blink. (The alarm test is disabled when the oil concentration of the sample water
exceeds the oil alarm point in the running state.)
Press "Esc" when the alarm operation test ends. "Running" is displayed back.
