What does a Weight Tester do?
Tends machine that records variations in weight along sample strip of paper or other material: Inserts end of sample strip into testing machine to obtain reading on graph of basic weight of sample. Turns dial to bring weight indicator to center line on graph to calibrate machine for weight of material tested. Starts feed rolls that carry sample strip through machine to record variations in weight of material on graph. Calculates percentage of variation in material weight, using formula or chart. Fills machine ink reservoir, using dropper.
