5.3.3 How to sample
Step 1: Remove a new sampling swipe from a package.
Note: A sampling swipe may be reused several times until any of the following
occurs:
• an Alarm is recorded
• the swipe becomes visibly dirty
• the swipe becomes deformed or damaged
Step 2: Sample in the center of the bottom 1 in. (2.5 cm) square of the swipe as shown
in Figure 5-14.
To sample, apply firm pressure (enough to bruise a tomato) to the back of the
swipe with your index finger while dragging the swipe in a straight line across
the surface being sampled. Lift the swipe when repositioning.
