5.00 SETUP
5.10 Installing/Replacing Batteries
1. Using a slotted screwdriver or coin,
loosen the battery cover screw located
at the end of the unit by turning the
screw counterclockwise.
2. Insert four (4) AA , 1.5 volt akaline
batteries into the battery sleeve.
Insert them in the direction indicated
on the top of the sleeve. Use of NiCad
rechargeable batteries is not
recommended.
3. Replace battery cover by first inserting
the tab of the cover into the slot of the
housing and pressing the cover into
place. Tighten the screw by turning it
clockwise.
NOTES:
1. If battery cover will not close, confirm that the batteries are inserted in the
proper orientation. Refer to step 2 above.
2. After replacing the battery, make sure the proper units of measure are
selected.

7.10 Checking Calibration
It is important to check the calibration of the DTMB
frequently to insure that the gauge continues to
perform 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
the application
2. Setup DTMB by inserting sample into Thickness Compensator and
performing a Gravity Correction (Zero) if using a horizontal material path.
Refer to QuickStart Instructions, Section 4.0.
3. The DTMB should display a value equal to (or within quoted accuracy
specification) of the known Weight “W”. If not, refer to Field Calibration
Adjustment, Section 7.20.
