Jumps to zero at low flow.
L-Series Meters and LC-Series Controllers feature a programmable zero
deadband. The factory setting is usually 0.5% of full scale. This can be adjusted
between NONE and 3.2% of full scale. See page 22.
MAINTENANCE AND RECALIBRATION
General: L and LC-Series Water Flow Meters and Controllers require minimal
maintenance. The primary cause of damage and/or long-term inaccuracy in
these devices is contamination and/or corrosion damage. Water should be
filtered for particulates or biological materials that may grow in the device.
When removing these units from the line for any extended period of time,
make an effort to remove all of the water from the device, as deposits of
calcium or other soluble minerals can affect the accuracy of the device.
Recalibration: The recommended period for recalibration is once every year. A
label located on the back of the device lists the most recent calibration date.
The device should be returned to the factory for recalibration within one year
from the listed date. Before calling to schedule a recalibration, please note the
serial number on the back of the meter. The Serial Number, Model Number, and
Date of Manufacture are also available on the Model Info screen (page 24).
Cleaning: L and LC-Series Flow Meters/Controllers require no periodic cleaning.
If necessary, the outside of the meter can be cleaned with a soft dry cloth.
Avoid excess moisture or solvents.
