on the outside wheel of the gage. The mean of
these two points is considered one reading.
When the material picked up by the center wheel
is speckled or otherwise poorly defi ned, select
and arbitrary point of 1/3 the distance from „solid
pickup“ to „no pick up“.
If the coating contains solvents which evapora-
te quickly or where the solids content is low, at
least one additional reading should be taken on
a freshly coated sample and the mean of the two
readings calculated.
On units equipped with a rotating scale, the
pointer is placed at the point at which the coating
ceased to be picked up by the center wheel. The
reading is determined by locating the number on
the black scale indicated by the center line of the
triple engraved mark found on the outside body of
the gage. The rotating scale increases accuracy
and precision of reading by minimizing the effects
of parallax.
On Moving Samples:

Measurements on moving surfaces may involve
operations which may be hazardous. These
