1. Set the top (small) "o" ring located on the plunger rod on zero, down against the instrument's flange, or on desired maximum force.
2. Holding the instrument firmly, press slowly against a given door at a point approximately handle-high and 30 inches toward the handle from the door's hinges.
3. Read the amount of force required to open the door on the plunger scale closest to the bottom of the small "o" ring.
