After the last measurement, the Gage will calculate a Zero which represents the
average of all the
Zn Zero
readings taken.
N 1 Pt Adjustment
For rough zinc surfaces (i.e. zinc spray metallizing), it may be desirable to adjust the
Gage to a known thickness, such as a shim placed over the zinc, rather than adjusting
it to zero. This ensures the Gage measures the thickness of paint over the metallizing
“peaks”.
1) Select
N 1 Pt Adjust
from the
Cal Settings
menu.
2) Press
(+)
to select the number of readings to be used to obtain an average, typically
3 to 10 readings. The greater the variation between readings, the more readings should
be taken to obtain an average.
3) Repeatedly measure the known thickness reference on the unpainted galvanized
part. The Gage will wait two seconds between readings to allow the user to correctly
position the probe on the surface. After the last measurement, the Gage will calculate
and display the reading which represents the average of all the measurements taken.
If the expected reading is not obtained (within tolerance), lift the probe from the surface
and adjust the reading down
(-)
or up
(+)
to the expected thickness and press .
NOTE:
The reference thickness should be similar to the expected paint thickness.
