MarTest. Test Indicators
Applications
The test indicator serves as an instrument for comparative
measurements. It can be used in any type of measuring stand.
Due to the swivelling feature of the probe and the reversal of its
sensing direction, the Mahr Test indicator is suitable for many
measuring and checking tasks.
Areas of application i.e.:
• run-out and concentricity checks of shafts and bores
• checks of parallelism and alignment of flat faces in engineering
and tool making
References to application:
90°

90°

α
For accurate measurements the axis of the contact point must
be perpendicular to the measuring direction. If this is not
possible, it is necessary to multiply the reading on the dial with a
correction factor, which depends on angle a. The correction
factor is negligible for angles below 15°.

• Mahr Federal’s leveling table, TE-20, permits you to quickly
bring the surface of a part into alignment with a surface
plate in both planes. Completely eliminates shimming. Saves
so much time that, used only occasionally, it will pay for
itself in two weeks.
• The top plate is stress-relieved steel providing about 67
square inches of work area. It is drilled and tapped for fixtures. Fine pitch screws and large knobs assure precisely
controlled adjustments. Works with any type of height
gage.

How to order
How to Order Your Dial Indicator and Accessories —
1. Select the type of Indicator you require. Check the
specialized types as well as regular ANSI/AGD models.
2. Choose the Model best suited to the magnification,
range and viewing needs of your job.
3. Accessories. These are important because they greatly
increase the speed, efficiency and convenience of
obtaining desired results. A wide selection of Mahr
Federal dial indicator accessories are shown in this catalog.
4. Options. You are not restricted to the normally furnished equipment mentioned above. A wide choice of
optionally available points, backs or dial arrangements
can be specified at little or no extra cost. We maintain
the most extensive stock of indicators and gages for
dimensional measurement available anywhere. Items
which are in stock are normally shipped within five
working days. If you need them sooner, inquire when
ordering. We can often make next-day deliveries.
Understandably, some of the items in this catalog are
not always in stock or are special order items, which
take a little longer to ship.
If you need help in determining what Indicators right
for your application, just ask us. Contact Mahr Federal
Customer Resource Center:
1-800-333-4243
One of our experienced professionals will give you courteous, professional advice that can save you time and
money.
Replacement indicators
Although Mahr Federal dial indicators are known for
their lifetime service, it is not uncommon to change an
indicator back, contact point, dial or to even add an
accessory to suit your latest application.
When ordering a replacement dial indicator for a
specific application, always verify the configuration
of the indicator. Ordering a replacement using the
standard model number shown on your indicator
may not provide you with the configuration or
accessories you desire.

Dial Indicators
Selecting the right ANSI/AGD type
Since modern manufacturing involves a wide
range of tolerances, choosing a dial indicator
might be difficult, especially since the number
of indicators available is so vast. The following
guidelines were prepared to assist you in
selecting the right model for your application.
If your tolerance spread is .006in (±.003in), then, the most suitable
minimum graduation value is .0005in.
Consider four characteristics when selecting a dial indicator:
• Minimum Graduation Value — value of the smallest
graduations marked on the dial. From several different
values available from Mahr Federal, select the one which
is closest to 10% of the tolerance spread of the work
you are measuring. This assures that the tolerance will
span about ten divisions of the dial
• Size — represents the bezel diameter. Make your selection on the basis of space available for the indicator and
the distance from which it will be viewed. The Indicator
photograph shown on the first page of each ANSI/AGD
Group is full scale. Simply place the page which illustrates the Indicator at the expected viewing distance,
and choose the size that offers you the best readability
and is the proper size for your fixture. Mahr Federal's "C"
size bezels (ANSI/AGD Group 2), which have a diameter
of 2-1/4in, are the most popular.
• Range per Revolution — represents the
distance the spindle travels with one
complete revolution of the dial hand. From the
dials available in the size and minimum graduation
value you chose, select the range per
revolution which allows the tolerance spread
to occupy 1/10 to 1/4 of the dial.
• Total Range — the maximum distance over which the
indicator spindle can travel. Usually, this represents 2-1/2
revolutions of the hand, which is adequate for most
needs. Sometimes, however, this may not be adequate
for your application and a special total range may be
necessary.
Your tolerance spread is .006in. You have chosen an ANSI/AGD Group
2 (Mahr Federal "C" Size) dial with a minimum graduation value of
.0005in. Mahr Federal offers four indicator types in this size and minimum graduation value. Of these, type C5M has a range per revolution
of .030in which is about midway between your tolerance extremes.
You selected a C5M indicator. Your total range, however, needs to be at
least .200in so the spindle can clear the lip of your part. But, the longest
range available in the C5M indicator you need is only .075in.
Special ranges up to .400in are available for this
indicator type. Select the closest range for your
application (for Model C5M, you would select .250in).
If the range you need is not listed under the "Special
Ranges" category, contact Mahr Federal. Chances
are we can supply the range you need.

Dial Indicators
Easy Reading, Single Revolution Dial Indicator
... assure correct readings every time.
A practical solution for inspectors and machine operators who need to
eliminate the potential for indicator misreadings. No matter how far
out of tolerance a part may be, the needle of a one revolution indicator will always stay in the red, non-read zone — no passing zero again —
no reading errors.
• No limited contact travel
• Shockproof “Following Movement” always keeps the hand within a
single revolution.
• Alternate contact points, backs and other accessories are optionally
available.
• Metric dials are yellow
• One-piece case design
• Inserted precision bearings
• Available in ANSI/AGD Group 2 size

Dial Comparators —
Design Features
• Built-in compression spring assures constant
measuring force over entire
range.
• Shockproof movement.
The precision ball of the first transmission lever rest on the
lapped sapphire plane surface of the upper end of the measuring spindle. If the spindle is subject to severe impact, the plane
surface is automatically raised, thus preventing transmission of
the shock to the movement.
• One-piece housing encloses the movement and provides maximum protection against shock and damage.
• Lockable fine adjustment screw.
• Self-contained movement permits unit to be removed and
replaced quickly and easily for repair or maintenance.
• Corrosion-proof, hardened,
stainless steel mounting shank
and measuring spindle.
• Maximum sensitivity and accuracy are ensured
by jewelled bearings of movement in conjunction with precision gears and pinions.
• Sleeve seal ring offers ball guide
protection against contaminants.
• Waterproof option available — features rubber bellows at
measuring spindle, sealed screws and splash guard cover.
• High-precision ball guide construction for the measuring
spindle prevents tilting and virtually eliminates friction and
play assures high measurement accuracy and minimal hysteresis.
• Dial comparators with ball guide are particularly insensitive
to lateral forces acting on the spindle (Dial Comparators
1010 and 1050 feature high-precision sleeve bearings for the
spindle).
• Adjustable tolerance
markers facilitate setting
and observing tolerance
limits.
• Measuring spindle retraction with either a screw-in cable or
lifting knob.
• Fine-line scale for easy reading.
• Pointer moves over limited sector.

Testing Test Indicators, Dial Indicators and Dial Comparators per DIN
All test indicators, dial indicators and dial comparators are
inspected per ANSI or DIN Standards.
Optimar 100 is a bench-top unit with a measuring range of
100mm/4in. A high resolution measuring system, Optimar
100 complies with the Abbe principle to insure the most precise measurements possible. For more details see Catalog
3754921, Dimensional Metrology, Length, Form, Gear and
Surface Texture Measuring Systems.
The following defined parameters, are tested:
• DIN 2270 (test indicators)
• DIN 878 (dial indicators)
• DIN 879 (dial comparators)

Dial Indicators
Indicator Calibrator with Digital Readout
Model 400B-50
• A precision, benchtop instrument, providing a convenient
means for calibrating a wide variety of precision measuring
instruments, including dial indicators, test indicators,
AirProbes®, electronic gage heads, or any other device that
magnifies the linear displacement of a contact point or
measuring spindle – user selectable for either inch or metric
units.
• Two calibration stations provide high magnification and
long range in a single unit. Incorporated within the micrometer-style control is a rotary encoder which senses the
amount of movement and displays the actual displacement
on a digital readout.
• Digital readout consists of six high visibility, LED digits and
operator-accessible controls for inch/metric units, range
selection, zero reset, and polarity/direction.
