Step 5.
Rotate the sampler until the test spots are in a down
position (Figure 4-11). Force the liquid from the four
ampoules through the formed channels to the test spots
to ensure wetting.

over the test spot, with test spot or arrow pointing
down.

Put your thumb over the center test spot and swing the
hinged heater assembly away from the test spot (Figure

WARNING
The heater produces hot vapors and is hot to the touch.
Keep away from bare skin and clothing after ampoules are
broken. As a minimum, protective mask and gloves should be
worn when using the M256A1 Kit.
