The units and resolution of the differential thickness are the same as those selected for
the thickness measurement.
When you press
[SAVE/SEND]
while in
NORMAL
or
% RATIO
differential modes,
the 38DL PLUS saves the actual thickness value along with the “D” flag, indicating
that the
Differential
mode is active.
To activate and configure a differential mode
1.
While in the measurement screen, press
[SETUP MENU]
.
2.
In the menu, select
DIFF
.
3.
In the
DIFF
screen (see Figure 8-2 on page 115):
a)
Set
DIFF ENABLE
to
ON
to activate the differential function.
b)
In
DIFF MODE
, select one of the three differential modes:
○
NORMAL
: Shows the actual thickness along with the difference between
the actual thickness measurement and the
REF VALUE
that you entered.
○
% RATIO
: Shows the actual thickness along with the percent difference
from the
REF VALUE
that you entered.
○
REDUCTION RT
: Shows the actual thickness as well as the percent
difference between the actual thickness and the former value. The former
value is the thickness of the metal prior to the bending process. Use this
mode for metal bending or other application in which you need to track
the percentage of wall thinning.
c)
When
DIFF MODE
is set to
NORMAL
or
% RATIO
, in
REF VALUE
, enter
the reference value.
