4 : Operation
After configuration, follow below procedures before operation.
4-1 : Warm-up
Turn ON the power.
For accurate measurement, the electronics needs 30-minute warm-up time to stabilize.
Once turn OFF the power and turn ON the power again, wait for 10-minute for
electronics warm-up.
In this case, remove bubbles and verify no bubbles remain inside of the flowtube.
Bubbles will prevent accurate measurement.
4-2 : Zero adjustment
A zero adjustment is very important for accurate flow rate measurement.
Follow the procedures according to the version of the main unit.
Version 1 (ZERO: Variable resistor)
(1) Fill the fluid inside of the flowtube and verify the fluid stops.
(2) Zeroing the flowmeter.
Connect a digital voltmeter or tester between CHECK+ and CHECK- terminals of
the main unit.
Adjust the variable resistor so that the voltage measured by the digital voltmeter
becomes 0 ±20 mV.
