2.11 Using LO / HI Thickness Limits (DM4, DM4 DL)
WARNING: If a file containing normal thickness (THK) data is
currently active, changing the LO or HI limit replaces any set-
tings previously stored in the file.
LO and HI limits identify readings that violate user set lower and
upper limits. When LO and/or HI limits are set, a reading that
violates either causes the red LED (front panel) to light.
A flashing plus sign (Figure 2-15) indicates the reading exceeds
the HI limit. A flashing minus sign (Figure 2-16) indicates a read-
ing that is less than the LO limit.
To set and enable LO and HI limits press
until SPEC illumi-
nates.
Figure 2-16
Press or until (lower limit) or (up-
per limit) appears in the display.
Press
to display current status, On or Off. Use or
to turn either alarm mode On or Off.
Setting LO and HI Limits:
With the desired alarm mode On, press
to display the cur-
rent limit setting. Use
or to set the limit (0.020 to 20.00";
0.5 to 500 mm). Press
again to return to or
display. Press to return to THK mode.
2.12 Differential Measurement (DM4, DM4 DL)
Differential measurement mode displays the difference between
the measured thickness and a nominal value set by the user. To
enter dIF mode, press
until SPEC illuminates.
Then press
or until appears in the display.
Press
to display current status, On or Off. Use or
to turn differential mode On and Off
Setting the Nominal Value:
Press
to display the current nominal value setting.
Use
or to set the desired value. Press again to
return to
display.
To perform differential measurement, with dIF mode On, return
to THK mode
and follow the measurement procedure in
Section 2.8.
Figure 2-17
Figure 2-17 shows a differential reading that is 0.059 inch greater
than ( ) the user set nominal value. In Figure 2-18 the actual
measurement is 0.003 inch less than ( ) the nominal.
To disable differential measurement, follow the procedure at the
beginning of this section.
