3.4.3
Power on
When switching the power on for the first time, the flowmeter will run automatically
according to the parameters you put last time (the meter is calibrated before leaving factory).
After the flowmeter is installed and powered on, you can check its status in M04 menu; if it
displays “*R”, it indicates that the flowmeter is running normally.
If you use the flowmeter in a new environment, you need to input related parameters.
Any parameters you input would be kept in its memories forever till you correct them again.
If you need to adjust its installation position or the position of the transducer, you need to
input and set related parameters again of the flowmeter to ensure normal use.
DO always finish all tasks when running. No matter in any displays, tasks including
measurement and output should be finished as usual.
