Section 1 General Information
1.0 Caution
• Remember, only charge your Indicator when the battery symbol is shown on
the display.
• Avoid extreme temperatures, direct sunlight or below freezing for extended periods.
• Avoid dropping the Indicator. Avoid shocks to the contact point and spindle. Do not
apply any radial force to the spindle.
• If the indicator is stem-mounted, protect the indicator from being struck or bumped
to prevent stem/case mechanical alignment damage.
• Do not over-tighten the mounting mechanism and use clamp mounting rather then set
screws, if possible, to prevent damage to the spindle.
• Frequently clean the spindle using a dry cloth or a chamois to prevent sluggish or
sticky movement. Isopropyl alcohol may be used to remove gummy deposits on metallic
parts. Do not apply any type of lubricant to the spindle and do not use solvents.
• Avoid any disassembly or modification of the indicator, other than what is outlined
in “Accessories”.
• Avoid using anything that might damage the buttons when pressing the buttons.
• Use the appropriate gage stand or indicator holder for the job intended.
1.1 Basic Operating Instructions
1. Turn on your tool, check the lower left of the display to see if the battery
symbol is showing, Fig.1A. If the battery symbol is showing then go to the
“Rechargeable Battery Care and Maintenance” section. If there is no battery
symbol visible then the battery is charged.
2. Lightly clean the contact point.
3. Fasten the indicator into the appropriate holding device.
4. You can turn the indicator on by pressing any button.
5. If applicable, pick the unit of measure, inch or millimeter by pressing the IN/mm
button. Note: standard metric indicators do not have this function available.
6. Place the indicator perpendicular to the reference surface being measured. Allow
enough movement to be able to take a higher or lower measurement. Note: This is one
of many possible ways to use the tool.
7. Zero Sequence: Zero the tool by pressing the ZERO Button. When you press the
ZERO button the display will show a dashed line as seen in (Fig.1B).The dashed line will
incrementally disappear from left to right (Fig.1C); Make sure not to move the spindle
during this time.This is a visual reminder to wait for the tool to zero out.This will happen
each time the tool is zeroed, and takes less than a second to complete.
8. Lift the spindle to remove the reference surface, and carefully place the piece to
be measured under the spindle making contact with the surface. The value measured
on the display will be the difference between the reference and the measured piece.
9. The indicator can be turned off by pressing and holding the ON/OFF button for 3
seconds.
Note: the unit will automatically enter sleep mode in 30 minutes, if left unattended.

Section 3 Rechargeable Battery
3.0 Rechargeable Battery Care and Maintenance
The rechargeable battery in your tool will last far longer when maintained properly.
When the charge on the battery is getting low, a battery symbol will be visible on the
middle left side of the display (Fig.13C). When you see this icon, charge the battery at
the next opportunity. Fig.12 shows where to attach the USB Micro B side of the cable
into the tool. The USB cable is keyed to plug in only one way, check the orientation of
the cable end and the USB port before plugging in the cable. The tool may be used
while it is plugged in. See Fig.13A-E for information about the changes to the battery
icon and what they mean.
If you wait too long to recharge the battery, the tool will automatically shut down
completely to conserve the remaining charge on the battery. The battery must have a
minimum charge to be recharged. If the tool will not turn on with the on/off button, then
you must charge the tool. When the tool is plugged in after being completely shutdown,
the tool will go through an initialization startup phase, See “Startup Sequence” in this
manual, Pg. #. We recommend that the tool only be charged when the battery icon is
visible to help prolong battery life. Depending on use, the time between charges could
be weekly under heavy use or monthly under light use.

ENGLISH
3.1 Startup Sequence
1. After the tool has shut down completely, and you have plugged it in to charge,
the tool will flash a sequence of information on the display, see the examples below
(Fig’s.14-17).This is normal for the indicator and a description of the screens is shown.
2. At the end of the sequence you will re-initialize the measurement system. When
“CAL” is displayed (Fig.18), move the spindle slowly in and out, until the display starts
to show measurements. This movement will calibrate the indicator.
3.2 Calibrate
1. If you don’t move the spindle, “Cal” will stay on the display for about 10 seconds
and the display will go blank.
2. To return to “Cal” mode move the spindle or quickly press the on/off button.
3. If you move the spindle to fast it will take longer for the tool to initialize

Note: Remember, to ensure the specified IP67 performance, the following items will
need to be intact and securely assembled onto the indicator.
• Spindle Bellows
• Back lug with Gasket
• Stem Cap
• Data Output Cover or Data Cable with Gasket
Note: All items that have screws will need to be secured at least finger tight.
4.1 Accessories
The 2900 series comes standard with a Lug-
On-Center back. The back is easily removed
by unscrewing the four screws as shown in
Fig.19.
Do not touch any of the inner workings of the
indicator, and protect them from liquids, dust,
and any other foreign matter. Replace the
back-lug as soon as possible. Some examples
of the different back-lugs are listed below.
The Contact Point is another one of the parts
on your indicator that is interchangeable. The
contact point can be removed by carefully
while holding the spindle firmly with one hand
and then unscrewing it counter- clockwise
with your other hand. Replace the contact point
the same way, turning the tip on clockwise.
Remember to tighten the tip finger tight.
Excessive radial rotation of the spindle shaft
may cause your indicator to stop functioning
properly. Special contact points are listed on
the next page.
These backs, contact points and all of the available indicator accessories can be found
in your Starrett catalog or online at www.starrett.com/catalogs.
