8. Using Special Functions
This chapter describes how to use special 38DL PLUS functions and modes. The
38DL PLUS has many thickness measurement features. Although the features
outlined in this section are not required for basic thickness operation, they can make
the gage a more versatile instrument.
8.1 Activating and Configuring a Differential Mode
The 38DL PLUS includes differential modes to easily compare the actual
measurement with a reference value that you enter. The actual thickness
measurement appears on the thickness display and the differential value appears in
the differential display area (see Figure 8-1 on page 113).
