Set the graduated container on a level surface
and note the fluid volume (
Important:
When you are reading the
graduated container, you must set the
container on a level surface.
Important:
When you are reading the
graduated container, read the fluid volume in
the graduated container at the lowest point
of the fluid-surface curve.
Important:
Small errors reading the fluid
volume in the graduated container will
significantly impact the accuracy of the
sprayer calibration.
