(3) Simple Adjustment to a Known Thickness
It is sometimes desirable to adjust the Gage to a
known thickness, such as a shim, rather than
adjusting it to zero.
Measure the object. If the expected reading is not
obtained (within tolerance), lift the probe from the
surface and adjust the displayed reading down (-) or
up (+) to the expected thickness. Hold the button
down to increase the rate of adjustment.
(4) Average Adjustment to a Known Thickness
On rough or curved surfaces a preferred method is
to take several readings on the known thickness and
average the result.
1.Select
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. The Gage will wait 2 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 .
2-point Calibration Adjustment
-Preferred for very unusual substrate materials,
shapes or conditions. Provides greater accuracy
within a limited, defined range.
This method requires taking two readings at known
thickness values: a thin value (often zero) and a
