5.20 Using AC-Adapter
The optional AC-DTMX AC Adapter can be
used as an alternative to batteries. Plug one
end of the AC-adapter into an appropriate
AC outlet and the other end into the recepta-
cle located on the side of the DTMX.
Note:
1. When using the AC adapter, do not remove the batteries as they are used
to save the data in memory when the power is turned off.
2. If the units of measure were changed while the AC-Adapter was in use, the
units of measure will revert back to the one’s selected prior to the change.

8.10 Checking Calibration
It is important to check the calibration of the DTMX
frequently to insure that the gauge continues to per-
form within factory specifications. Implementing a
periodic calibration check will help identify when
(and if) the gauge goes out of calibration due to
unreported damage, overload, or other unknown
reason.
To check the calibration:
1. Suspend a known weight “W” from the
process material in either a vertical or
horizontal direction, best simulating
the orientation that will be used during
actual measurement. Fix the process
material at one end.When fixing the
process material horizontally, use a
roller (or other free-rotating guide) prior to fixing the known weight. Refer
to sketches. Select a weight within the expected operating tension range of
the application
2. Setup DTMX by inserting sample into Thickness Compensator, setting
Material Rigidity Selector and performing a Gravity Correction (Zero) if
using a horizontal material path. Refer to Quick Start Instructions,
Section 4.0.
3. The DTMX should display a value equal to (or within quoted accuracy
specification) of the known Weight “W”. If not, refer to Field Calibration
Adjustment, Section 8.20.
