Setting Audible Limit Alerts - Check-line DC**-3000PS series Operating Instructions Manual

4.4 Zero Offset
In this menu item, a constant positive or negative value can be set. This value is
automatically added to the measured value or subtracted from the measured value
every time a measurement is carried out. The display then shows the addition or the
difference. Moreover, the zero offset setting is always indicated below in the display
as a reminder.
This measuring mode is useful when determining the upper coating layer of a multi-
layer system. If the lower layer(s) is (are) known and show an adequately uniform
thickness, the coating thickness of this (these) layer(s) can be set as a negative
offset value. The display then only shows the thickness of the top layer.
When measuring coated rough metal surfaces, this mode can also be selected. In
this case, the roughness effect, which is determined on the basis of the uncoated
rough metal surface, is set as a negative offset value. The instrument will then
display the coating thickness above the peaks of the rough surface.
