The units and resolution of the differential thickness are the same as those selected for
the thickness measurement.
When you press
[SAVE]
(with the optional datalogger) while in the
NORMAL
or
% RATIO
differential modes, the 45MG 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.
In the measurement screen, press
[SETUP]
, and then select
DIFF
.
2.
In the
DIFF
screen (see Figure 7-2 on page 129):
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
entered.
•
% RATIO
: Shows the actual thickness along with the percent difference
from the
REF VALUE
entered.
•
REDUCTION RT
: Shows the actual thickness, in addition to 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 any other application in which you need to
track the percentage of wall thinning.
c)
When
DIFF MODE
is set to either
NORMAL
or
% RATIO
, enter the
reference value in the
REF VALUE
text box.
