Zero Adjustment
Introduction Adjust the flowmeter so that the measured instantaneous flow rate will be zero
when the fluid stands still in the detector.
Notes:
• Zero adjustment is very important for accurate flow measurement.
Before operating the unit for the first time, be sure to zero the
flowmeter.
• Before zero adjustment, make sure the detector has proper Class 3
grounding and that the fluid to be measured is charged into the
detector and is standing still. Zero adjustment is possible when the
flow speed is 0.2 m/s or below, but wait until the fluid completely
stops (flow speed: 0.0 m/s) for accurate adjustment. Otherwise,
output errors may result.
