Basic Operations
The dial indicator can be used in many ways and
the magnetic base can be positioned on flat or
round surfaces. The list below detail guidelines
for use:
1. Use the ON/OFF switch on the magnetic
base whenever moving the unit to help avoid
marring the surface that it is resting on and to
prevent sudden jarring which could damage
the internal components of the indicator.
2. Make adjustments to the support assembly
only with the base magnetically secured to
a steel or iron object. This will help guard
against damage to the indicator should the
base fall.
3. Loosen the lock knobs to adjust the height
and angle of the support boom. Trying to
defeat the locks to move the indicator a small
amount will cause premature wear on the
system.
4. Gently, try to rock the base after turning the
switch to the ON position to ensure that the
setup is secure.
Adjusting the Assembly
The magnetic base and indicator can be posi-
tioned in many ways. The bottom of the magnetic
base is notched to allow for mounting to curved
surfaces as well as having a ground, flat surface.
The back of the base is ground flat for mounting
as well.
Care must be taken to secure the base
to a suitable surface. Hanging the base upside-
down or from the side of a machine may cause
the unit to fall. Also, sheet metal may not have the
mass need to properly support the unit. Dropping
the dial indicator will reduce its accuracy and may
make it unusable.
Figure 5. The support assembly can be posi-
tioned in any fashion by loosening the 2 pivot
joints.
Figure 6. The indicator can be oriented in any
direction by loosening the mounting stud, loos-
ening the boom and raising the boom along the
column.
